GMAT Flashcards: Quant, Verbal & Data Insights Decisions
Build quick recall for the current GMAT with 300 original cards across Quantitative Reasoning, Verbal Reasoning, and Data Insights. The deck focuses on reusable concepts and decisions; full-length practice belongs in official or properly licensed question banks.
What the cards map
- Quant maps numeric forms, terms, rules, and formulas to their meaning, conditions, or use. Short scenarios ask for the operation, equation, or answer check that fits.
- Verbal maps passage and argument cues to purpose, scope, evidence, inference, reasoning flaws, and evaluation moves.
- Data Insights maps targets, constraints, source and display cues, metrics, and evidence states to the interpretation or decision they support. It covers Data Sufficiency, Multi-Source Reasoning, Table Analysis, Graphics Interpretation, and Two-Part Analysis.
Learning order
The mixed sequence keeps all three sections in rotation. Quant foundations come before algebra, models, and strategy checks; passage reading comes before argument evaluation; shared data literacy comes before the five Data Insights formats. Closely related prompts are spaced apart so one card does not cue the next.
Current-format boundary
This deck has no geometry lessons or formula drills, Sentence Correction, or the retired Integrated Reasoning section. It also excludes timing, scoring, test-center policy, full passages, large data sets, and response-pattern tricks.
Every card is an original compact concept or decision prompt. No official or competitor questions, answer choices, explanations, mark schemes, curriculum text, logos, or trade dress were copied or adapted. See the official GMAT exam content and Data Insights preparation guidance for the current exam boundary.

Kartice u ovom špilu
Kartica 1
Pitanje
Which numerator-and-denominator operation creates an equivalent fraction?
Odgovor
Multiply or divide the numerator and denominator by the same nonzero number. The fraction's value stays unchanged.
Kartica 2
Pitanje
What does data sufficiency ask you to determine?
Odgovor
Whether the information guarantees one answer. You usually don’t need to calculate that answer.
Kartica 3
Pitanje
How do you form a passage's main idea?
Odgovor
Combine the passage's central topic with its main claim about that topic. The answer should cover the whole passage at the right level.
Kartica 4
Pitanje
What does multiplying a decimal by 10ⁿ do when n is a positive integer?
Odgovor
It moves the decimal point n places to the right. Dividing by 10ⁿ moves it n places left.
Kartica 5
Pitanje
What makes information sufficient for a value question?
Odgovor
It forces exactly one value for the target. Different values that satisfy all conditions make it insufficient.
Kartica 6
Pitanje
How do you identify the passage's primary purpose?
Odgovor
Name what the author is doing with the topic: explaining, comparing, challenging, defending, or proposing. Keep content and action together.
Kartica 7
Pitanje
How do you find p percent of a quantity q?
Odgovor
Compute (p/100) × q. Translate “of” as multiplication.
Kartica 8
Pitanje
How can two valid cases prove insufficiency?
Odgovor
Make the cases produce different answers to the question. One clean counterexample pair is enough.
Kartica 9
Pitanje
How do you determine a paragraph's role?
Odgovor
Connect the paragraph to what comes before and after it. Decide whether it introduces, supports, qualifies, contrasts, applies, or concludes the larger discussion.
Kartica 10
Pitanje
A total of 45 is split in the ratio 2:3. What are the two parts?
Odgovor
18 and 27. The five ratio units are worth 45 ÷ 5 = 9 each.
Kartica 11
Pitanje
Why can an integer restriction change sufficiency?
Odgovor
It removes noninteger possibilities. A range containing many real numbers may contain only one integer.
Kartica 12
Pitanje
When is a product of signed factors negative?
Odgovor
Provided no factor is zero, an odd number of negative factors gives a negative product, while an even number gives a positive product. If any factor is zero, the product is zero.
Kartica 13
Pitanje
How should two data-sufficiency statements be tested initially?
Odgovor
Test each statement independently against the stem. Do not carry information from one statement into the other.
Kartica 14
Pitanje
What makes an integer greater than 1 prime?
Odgovor
It has exactly two positive divisors: 1 and itself.
Kartica 15
Pitanje
What should you do first on a detail question?
Odgovor
Return to the relevant lines and read their local context. Memory tends to preserve the topic while blurring qualifications.
Kartica 16
Pitanje
What is the divisibility rule for 2?
Odgovor
The last digit must be even: 0, 2, 4, 6, or 8.
Kartica 17
Pitanje
How do you test whether a fact is relevant?
Odgovor
Connect it to the requested target. A true fact that does not narrow the target adds no decision value.
Kartica 18
Pitanje
How far may a reading inference go beyond the text?
Odgovor
Only as far as the text strongly supports. Prefer the smallest justified step and reject claims needing outside knowledge.
Kartica 19
Pitanje
Why is prime factorization useful in GMAT arithmetic?
Odgovor
It exposes divisibility, factors, greatest common factors, least common multiples, and perfect powers.
Kartica 20
Pitanje
What must happen before quantities with different units are combined?
Odgovor
First confirm that their dimensions are compatible, then convert them to a common unit. Keep the unit attached through the calculation to catch mismatches.
Kartica 21
Pitanje
How do you apply a passage principle to a new case?
Odgovor
Extract the principle's required conditions, then test whether the new case has them. Surface similarity isn't enough.
Kartica 22
Pitanje
Which relationship connects distance, rate, and time?
Odgovor
Distance = rate × time. Rearrange only after the units are compatible.
Kartica 23
Pitanje
How do you find a least common multiple from prime factorizations?
Odgovor
Take every prime that appears, using the largest exponent present.
Kartica 24
Pitanje
How do you multiply powers with the same base?
Odgovor
Add the exponents: aᵐ × aⁿ = aᵐ⁺ⁿ.
Kartica 25
Pitanje
How is a weighted average computed?
Odgovor
Divide the total weighted value by the total weight. For groups, use group size as the weight unless another weight is given.
Kartica 26
Pitanje
What should a quick passage map record?
Odgovor
Each paragraph's role and major viewpoint, plus the passage's overall direction. Record structure, not a sentence-by-sentence summary.
Kartica 27
Pitanje
What does the principal square root symbol √x return?
Odgovor
For real x ≥ 0, it is the nonnegative number whose square is x. For example, √9 = 3, not ±3.
Kartica 28
Pitanje
When can bounds replace exact arithmetic?
Odgovor
When the bounds separate the viable decisions. Stop once every value in the interval leads to the same choice.
Kartica 29
Pitanje
How do you keep viewpoints separate?
Odgovor
Attach each claim to its speaker: author, critic, researcher, or group. Track agreement, disagreement, and any later qualification.
Kartica 30
Pitanje
How do “sum,” “product,” and “quotient” translate into algebra?
Odgovor
They mean addition, multiplication, and division, respectively.
Kartica 31
Pitanje
How do you reduce a fraction to lowest terms?
Odgovor
Divide the numerator and denominator by their greatest common factor.
Kartica 32
Pitanje
What evidence should determine the author's tone?
Odgovor
Evaluative words, qualifications, and the treatment of competing views. Topic alone doesn't establish approval, concern, or skepticism.
Kartica 33
Pitanje
When should rounding usually occur?
Odgovor
At the end, unless estimation already settles the decision. Early rounding can move a result across a cutoff.
Kartica 34
Pitanje
How do you convert a terminating decimal to a fraction?
Odgovor
Write the digits over the matching power of 10, then reduce. For example, 0.375 = 375/1000 = 3/8.
Kartica 35
Pitanje
When should you stop calculating in a sufficiency problem?
Odgovor
As soon as uniqueness is proved or disproved. More arithmetic cannot change the sufficiency decision.
Kartica 36
Pitanje
How do you spot an out-of-scope answer?
Odgovor
It introduces a person, period, cause, or consequence the passage doesn't address. Being reasonable doesn't make it textually supported.
Kartica 37
Pitanje
What is the percent-change formula?
Odgovor
For original > 0, percent change = (new − original) / original × 100%. Percent change from zero is undefined; negative baselines require context-specific interpretation.
Kartica 38
Pitanje
What makes information sufficient for a yes-or-no question?
Odgovor
It forces the same yes-or-no answer in every valid case. The underlying value may still vary.
Kartica 39
Pitanje
What preserves a ratio when its quantities are scaled?
Odgovor
Multiplying or dividing both terms by the same nonzero factor preserves the ratio.
Kartica 40
Pitanje
How do you reject a main-idea answer with the wrong scope?
Odgovor
Compare it with the whole passage. A detail-only answer is too narrow; a claim extending beyond the passage is too broad.
Kartica 41
Pitanje
Why should you track whether a variable is positive, negative, or zero?
Odgovor
Sign controls valid cases and operations. Squaring can hide sign, and division requires a nonzero denominator.
Kartica 42
Pitanje
How do you simplify subtraction of a negative number?
Odgovor
Change it to addition: a − (−b) = a + b.
Kartica 43
Pitanje
Whose purpose matters in a primary-purpose question?
Odgovor
The passage author's purpose. A theory or researcher may be described at length without representing what the author ultimately wants to do.
Kartica 44
Pitanje
When is the on-screen calculator most useful?
Odgovor
For tedious arithmetic after the setup is clear. It does not replace choosing the right relationship or denominator.
Kartica 45
Pitanje
In Data Sufficiency, what stem information applies when testing either statement?
Odgovor
Everything in the question stem. Stem facts remain active for each statement and for the combination.
Kartica 46
Pitanje
What is the divisibility rule for 3?
Odgovor
The sum of the digits must be divisible by 3.
Kartica 47
Pitanje
What does a transition paragraph often do?
Odgovor
It closes one line of thought and sets up the next. Its role depends on both sides, not only on its first sentence.
Kartica 48
Pitanje
When is a proxy measure useful?
Odgovor
When evidence shows it reliably tracks the target for the intended decision. Correlation may support prediction, but it proves neither causation nor suitability on its own.
Kartica 49
Pitanje
How do you find a greatest common factor from prime factorizations?
Odgovor
Take each shared prime to the smaller exponent.
Kartica 50
Pitanje
What is the arithmetic mean?
Odgovor
The sum of the values divided by the number of values.
Kartica 51
Pitanje
What units should a rate have?
Odgovor
One quantity per another, such as kilometers per hour. The denominator tells you what the rate is measured against.
Kartica 52
Pitanje
How do you divide powers with the same nonzero base?
Odgovor
Subtract the exponents: aᵐ ÷ aⁿ = aᵐ⁻ⁿ.
Kartica 53
Pitanje
What makes a paraphrase faithful to a passage detail?
Odgovor
It preserves the original meaning, scope, and certainty in different words. Shared keywords alone don't make it accurate.
Kartica 54
Pitanje
How do you recover a total from an average?
Odgovor
Total = average × number of values.
Kartica 55
Pitanje
How do you choose between two plausible reading inferences?
Odgovor
Choose the one with the tighter textual chain and fewer assumptions. Plausibility in the real world is secondary.
Kartica 56
Pitanje
What quick check can catch a calculator-entry error?
Odgovor
Estimate the order of magnitude and direction first. An exact result far outside that range deserves another look.
Kartica 57
Pitanje
How do you simplify a square root with a perfect-square factor?
Odgovor
Factor out the perfect square. For example, √72 = √(36 × 2) = 6√2.
Kartica 58
Pitanje
What makes a new example parallel to one in the passage?
Odgovor
The same logical relationship. Match cause, contrast, exception, or function rather than shared subject matter.
Kartica 59
Pitanje
When can work rates be added?
Odgovor
Add the stated constant rates when the workers operate simultaneously without interfering with one another. At 1/4 and 1/6 job per hour, together they complete 5/12 job per hour.
Kartica 60
Pitanje
What is the denominator in a percent comparison?
Odgovor
The stated reference value. “A as a percent of B” means A divided by B, then multiplied by 100.
Kartica 61
Pitanje
How do you translate “5 less than x”?
Odgovor
x − 5. The phrase “less than” reverses the spoken order.
Kartica 62
Pitanje
In Data Sufficiency, what should you check before testing values?
Odgovor
The full domain. Honor stated restrictions and implicit ones such as positive lengths or nonzero divisors before judging sufficiency.
Kartica 63
Pitanje
How do you add fractions with different denominators?
Odgovor
Rewrite them with a common denominator, then add the numerators. For example, 2/3 + 1/4 = 8/12 + 3/12 = 11/12.
Kartica 64
Pitanje
How do you distinguish description from argument in a passage?
Odgovor
Description presents what happened or what a view says; argument gives reasons to accept, reject, or revise a claim.
Kartica 65
Pitanje
How should you compare decimals with different lengths?
Odgovor
Append trailing zeros and compare place by place. For example, compare 0.47 with 0.4700, which are equal.
Kartica 66
Pitanje
How should combined statements be evaluated?
Odgovor
Intersect their constraints with the stem. The combination is sufficient only if every remaining case gives one answer.
Kartica 67
Pitanje
How do you find common ground between two viewpoints?
Odgovor
Look for the narrow claim both accept, even if they disagree about its cause, importance, or implications.
Kartica 68
Pitanje
How do you solve a proportion such as a/b = c/d?
Odgovor
Cross-multiply to get ad = bc, provided b and d are nonzero.
Kartica 69
Pitanje
How is average speed computed?
Odgovor
Total distance divided by total time. It is not usually the simple mean of the segment speeds.
Kartica 70
Pitanje
What does |x| represent?
Odgovor
The nonnegative distance from x to 0 on the number line.
Kartica 71
Pitanje
Why are strongly emotional tone descriptions often wrong?
Odgovor
They overstate measured academic prose. Match the answer's intensity to the author's actual language.
Kartica 72
Pitanje
What is the divisibility rule for 4?
Odgovor
The number formed by the last two digits must be divisible by 4.
Kartica 73
Pitanje
Can the ordinary percent-change formula be applied directly when the original value is zero or negative?
Odgovor
No. The ordinary GMAT rule assumes original > 0. Change from zero is undefined, and a negative baseline requires context-specific interpretation.
Kartica 74
Pitanje
Why can a true statement still be a wrong answer?
Odgovor
It may not answer the question asked. Check the task—main idea, detail, inference, role, or purpose—before checking truth.
Kartica 75
Pitanje
When must a weighted average lie between its component values?
Odgovor
When every weight is nonnegative and the total weight is positive. The average then lies between the smallest and largest component values.
Kartica 76
Pitanje
How do you express an integer n divided by d with remainder r?
Odgovor
n = dq + r, where q is an integer and 0 ≤ r < d for positive d.
Kartica 77
Pitanje
What does an inequality usually provide?
Odgovor
A range, not a unique value. It can still be sufficient if the question asks whether a threshold is crossed.
Kartica 78
Pitanje
How should you handle an EXCEPT detail prompt?
Odgovor
Verify four statements against the passage and select the one that isn't supported. Keep the reversed task visible while checking each choice.
Kartica 79
Pitanje
How should you set up a unit conversion?
Odgovor
Multiply by a conversion factor equal to 1, placing units so the unwanted unit cancels.
Kartica 80
Pitanje
Can two individually insufficient statements remain insufficient together?
Odgovor
Yes. They may repeat the same limitation or still leave multiple valid answers.
Kartica 81
Pitanje
For a positive base, how do you simplify a power raised to another power?
Odgovor
Multiply the exponents: (aᵐ)ⁿ = a^(mn).
Kartica 82
Pitanje
When can you infer that an author accepts a claim?
Odgovor
When the author endorses it directly or relies on it without distancing language. Merely reporting another person's view isn't endorsement.
Kartica 83
Pitanje
How should successive percentage changes be combined?
Odgovor
Multiply their factors. A 10% rise followed by a 10% fall gives 1.10 × 0.90 = 0.99, a 1% net fall.
Kartica 84
Pitanje
What are compatible numbers in estimation?
Odgovor
Nearby numbers chosen to make mental arithmetic easy, such as 203 ÷ 9.9 ≈ 200 ÷ 10 = 20.
Kartica 85
Pitanje
Which constraints are easy to overlook in a word problem?
Odgovor
Countability, positivity, distinctness, and capacity limits. Translate each noun and rule into a usable constraint.
Kartica 86
Pitanje
How do you state the exact disagreement between two viewpoints?
Odgovor
Identify one claim that one side accepts and the other rejects. Don't substitute a topic that only one side discusses.
Kartica 87
Pitanje
How do you represent three consecutive integers?
Odgovor
n, n + 1, and n + 2 for an integer n.
Kartica 88
Pitanje
How do percentage points differ from percent change?
Odgovor
Percentage points are the direct difference between percentages. Moving from 20% to 25% is 5 points and a 25% relative increase.
Kartica 89
Pitanje
What is a reversed-relationship trap?
Odgovor
It swaps cause and effect, support and conclusion, or the positions of two viewpoints while reusing familiar passage language.
Kartica 90
Pitanje
How do you multiply two fractions?
Odgovor
Multiply numerator by numerator and denominator by denominator, canceling common factors when convenient.
Kartica 91
Pitanje
How do direct and inverse proportion differ?
Odgovor
Direct:
y = kx; inverse:y = k/xforx ≠ 0.Kartica 92
Pitanje
How do you recover an original value after a percentage increase?
Odgovor
Divide the new value by the growth factor. After a 20% increase, original = new ÷ 1.20.
Kartica 93
Pitanje
When should absolute wording raise suspicion?
Odgovor
When the passage is qualified. Words such as always, never, entirely, and impossible require equally strong textual support.
Kartica 94
Pitanje
What should you identify first in Data Sufficiency?
Odgovor
The exact target and answer type. Decide whether the stem asks for a value, a comparison, or a yes-or-no result.
Kartica 95
Pitanje
What ending makes an integer divisible by 5 or by 10?
Odgovor
A last digit of 0 or 5 gives divisibility by 5; a last digit of 0 gives divisibility by 10.
Kartica 96
Pitanje
How should a Data Sufficiency condition be handled?
Odgovor
Translate it into a precise constraint before testing sufficiency. Keep it separate from the conclusion you want.
Kartica 97
Pitanje
How do you reject a half-right answer?
Odgovor
Test every part of it. One accurate clause can't rescue a second clause that distorts the passage or exceeds its scope.
Kartica 98
Pitanje
When you convert a positive measurement to a smaller linear unit, what happens to its numerical value?
Odgovor
It increases. Multiply by the number of smaller units in one larger unit.
Kartica 99
Pitanje
DS example: Is x > 5? Statement: x > 3. Is the statement sufficient?
Odgovor
No. Both x = 4 and x = 6 satisfy the statement, but they answer the stem differently.
Kartica 100
Pitanje
What is a⁰ when a is nonzero?
Odgovor
- The nonzero-base condition matters because 0⁰ is not assigned this rule.
Kartica 101
Pitanje
Which claim is the argument trying to establish?
Odgovor
The main conclusion. Find the claim supported by the other statements, then check that it answers the argument's central issue.
Kartica 102
Pitanje
When should the two statements be combined?
Odgovor
When neither statement is sufficient alone. Use both constraints at once and test the remaining possibilities.
Kartica 103
Pitanje
A positive number rounds to 8.2 to the nearest tenth. What interval contains it?
Odgovor
8.15 ≤ x < 8.25. The lower endpoint rounds up to 8.2; the upper endpoint rounds to 8.3.
Kartica 104
Pitanje
What should you check when the conclusion changes populations?
Odgovor
Whether the evidence applies to the new population. Results from volunteers, specialists, or one age group may not transfer to everyone.
Kartica 105
Pitanje
How should test values be chosen in Data Sufficiency?
Odgovor
Choose valid values that probe boundaries, signs, and distinct outcomes. Random easy values can miss the deciding case.
Kartica 106
Pitanje
How do you translate “A is 30% more than B”?
Odgovor
A = 1.30B. The percentage is based on B.
Kartica 107
Pitanje
When can one equation involving two variables be sufficient for a target?
Odgovor
When every valid solution gives the same target value, even if neither variable is unique. For example, x + y = 10 is sufficient to determine x + y.
Kartica 108
Pitanje
What does a correlation establish by itself?
Odgovor
Only that two things vary together. It doesn't establish which one causes the other or whether a third factor causes both.
Kartica 109
Pitanje
How do you divide by a nonzero fraction?
Odgovor
Multiply by its reciprocal. For example, 3/5 ÷ 2/7 = 3/5 × 7/2.
Kartica 110
Pitanje
Why is a ratio often insufficient for an absolute value?
Odgovor
A ratio fixes relative size but usually leaves the scale free. Many proportional pairs can share the same ratio.
Kartica 111
Pitanje
What is the divisibility rule for 9?
Odgovor
The sum of the digits must be divisible by 9.
Kartica 112
Pitanje
What matters most when applying a sample result to a population?
Odgovor
Representativeness. The sample must resemble the target population on traits that could affect the result.
Kartica 113
Pitanje
What should you check after solving a squared equation?
Odgovor
Check every allowed root. If positive and negative roots produce different target answers, the information is insufficient.
Kartica 114
Pitanje
What does a negative exponent mean?
Odgovor
It takes the reciprocal: a⁻ⁿ = 1/aⁿ for nonzero a.
Kartica 115
Pitanje
Which baseline makes a comparison informative?
Odgovor
The baseline relevant to the claim. Compare the outcome with what would otherwise have happened, not merely with an unrelated earlier figure.
Kartica 116
Pitanje
What risk appears when an equation factors into multiple branches?
Odgovor
Each branch may create valid cases. Test all branches against the stem before deciding sufficiency.
Kartica 117
Pitanje
How can you compare two positive fractions quickly?
Odgovor
Compare their cross-products. For a/b and c/d with positive denominators, compare ad with bc.
Kartica 118
Pitanje
What may be assumed from a Data Sufficiency diagram?
Odgovor
Only marked or stated facts. Do not infer scale, equality, perpendicularity, or midpoint status from appearance.
Kartica 119
Pitanje
What multiplier represents a p percent increase or decrease?
Odgovor
Use 1 + p/100 for an increase and 1 − p/100 for a decrease.
Kartica 120
Pitanje
Which statements count as evidence?
Odgovor
The statements offered as reasons to accept another claim. Evidence may be factual or assumed for the argument, even if it isn't proven in real life.
Kartica 121
Pitanje
Can a mean determine an individual observation?
Odgovor
Not by itself. A mean fixes the total, but different sets can have that total unless more constraints apply.
Kartica 122
Pitanje
What weakens a move from past evidence to a present claim?
Odgovor
A relevant change over time. New technology, prices, rules, or behavior can make the earlier evidence a poor guide.
Kartica 123
Pitanje
A value becomes 96 after a 20% increase. What was the original value?
Odgovor
- Divide the final value by the growth multiplier: 96 ÷ 1.2 = 80.
Kartica 124
Pitanje
How do extreme valid cases help in Data Sufficiency?
Odgovor
They expose whether the target can change. Test the smallest, largest, or boundary cases allowed by the conditions.
Kartica 125
Pitanje
How do you test for reverse causation?
Odgovor
Ask whether the alleged effect could instead cause the alleged cause. Productive teams may meet more because they are productive, not the reverse.
Kartica 126
Pitanje
Must a sufficient statement make every variable unique?
Odgovor
No. It only needs to make the requested target unique, even if other variables remain undetermined.
Kartica 127
Pitanje
A price rises 20% and then falls 20%. Does it return to its original value?
Odgovor
No. The multipliers give 1.20 × 0.80 = 0.96, so the final price is 4% below the original.
Kartica 128
Pitanje
Why can a voluntary survey be biased?
Odgovor
People who choose to respond may differ from those who don't. Strong opinions or extra interest can distort the sample.
Kartica 129
Pitanje
How do you expand a(b + c)?
Odgovor
ab + ac. The outside factor multiplies every term inside the parentheses.
Kartica 130
Pitanje
What should the final Data Sufficiency decision describe?
Odgovor
Which information set guarantees an answer. It should not report the target’s numerical value.
Kartica 131
Pitanje
What is the goal when solving a linear equation?
Odgovor
Isolate the variable by applying equivalent operations to both sides.
Kartica 132
Pitanje
DS example: Is integer n even? Statement: n = 7. Is the statement sufficient?
Odgovor
Yes. It guarantees one answer—no. A statement can be sufficient even when that answer is negative.
Kartica 133
Pitanje
When must an inequality sign reverse?
Odgovor
When both sides are multiplied or divided by a negative number.
Kartica 134
Pitanje
What must be checked before comparing two groups?
Odgovor
Whether they differ in other relevant ways. Age, experience, starting level, or incentives may explain the outcome instead.
Kartica 135
Pitanje
When is substitution preferable to elimination in a two-equation system?
Odgovor
Use substitution when one variable is already isolated or easy to isolate; use elimination when coefficients cancel easily.
Kartica 136
Pitanje
What should you build before analyzing Multi-Source Reasoning material?
Odgovor
A quick source map. Note what each tab or document contains, who produced it, and the relevant date or scope.
Kartica 137
Pitanje
How do you separate background from evidence?
Odgovor
Ask whether the statement supports a claim. Background sets context; evidence does logical work in moving the argument toward a conclusion.
Kartica 138
Pitanje
Which algebraic terms can be combined?
Odgovor
Terms with the same variable part and exponents. For example, 3x² and −5x² combine, but 3x² and 3x do not.
Kartica 139
Pitanje
When should you read the Multi-Source Reasoning question?
Odgovor
Before a deep read of every source. The question tells you which details deserve attention.
Kartica 140
Pitanje
What is a reliable first step for an equation containing several fractions?
Odgovor
Multiply every term by the least common denominator, then solve the simpler equation.
Kartica 141
Pitanje
Why does source provenance matter?
Odgovor
It defines what a claim can support. An internal forecast and an audited result do not carry the same evidentiary weight.
Kartica 142
Pitanje
What should you test when evidence comes from a different setting?
Odgovor
Whether the settings differ in a way that affects the result. A finding from one market, school, or climate may not carry over unchanged.
Kartica 143
Pitanje
What does an “and” compound inequality require?
Odgovor
The overlap of both solution sets. A value must satisfy both conditions.
Kartica 144
Pitanje
What should you compare before combining claims from two sources?
Odgovor
Their population, period, units, and definitions. Matching labels can hide different scopes.
Kartica 145
Pitanje
How can a third factor undermine a causal claim?
Odgovor
It may explain both events, so their correlation no longer establishes a direct causal link by itself. Hot weather can raise both cold-drink sales and pool attendance.
Kartica 146
Pitanje
What do one, zero, or infinitely many solutions mean for two linear equations in two variables?
Odgovor
The lines intersect once, are parallel and distinct, or are the same line, respectively.
Kartica 147
Pitanje
How should records from separate sources be linked?
Odgovor
Use a shared key with the same meaning in both sources, such as product code and month. Do not join on a vague label alone.
Kartica 148
Pitanje
How do you factor 6x + 9?
Odgovor
3(2x + 3). Pull out the greatest common factor.
Kartica 149
Pitanje
When does nonresponse threaten a survey result?
Odgovor
When nonrespondents may answer differently from respondents. A high response count doesn't fix a systematic missing group.
Kartica 150
Pitanje
What is the first step when two sources seem inconsistent?
Odgovor
Compare definitions, dates, units, and aggregation levels. Many apparent conflicts come from mismatched frames.

Kartica 151
Pitanje
When can you use the zero-product property?
Odgovor
After rewriting a product equal to zero. If (x − 2)(x + 5) = 0, then x = 2 or x = −5.
Kartica 152
Pitanje
How does an inference differ from a stated fact?
Odgovor
A fact appears directly in a source; an inference must follow from the sources without an extra assumption.
Kartica 153
Pitanje
Does a higher percentage by itself prove a higher count?
Odgovor
No. The underlying totals matter. Twenty percent of 1,000 is more than fifty percent of 100.
Kartica 154
Pitanje
What does an “or” compound inequality require?
Odgovor
The union of the solution sets. A value may satisfy either condition or both.
Kartica 155
Pitanje
What does a blank or omitted value establish?
Odgovor
Only that the value is not provided. It does not establish zero, no change, or failure.
Kartica 156
Pitanje
How do you recognize an intermediate conclusion?
Odgovor
It is supported by one claim and supports another. It acts as both a conclusion and a premise in the same argument.
Kartica 157
Pitanje
What should you do before writing equations for a two-quantity word problem?
Odgovor
Define each variable with its unit, then translate one independent relationship per equation.
Kartica 158
Pitanje
Why should cross-source events be placed in time order?
Odgovor
Sequence separates prior conditions from later outcomes and prevents using future information as an earlier cause.
Kartica 159
Pitanje
When should candidate solutions be checked in the original equation?
Odgovor
Always after a step that may introduce solutions, especially squaring both sides or clearing variable denominators.
Kartica 160
Pitanje
How can switching from one measured outcome to another create a gap?
Odgovor
Evidence about one metric may not support a conclusion about another. More website visits, for example, don't by themselves mean more sales.
Kartica 161
Pitanje
What makes a source relevant to a claim?
Odgovor
It supplies evidence for a required link in the claim. Related background alone is not enough.
Kartica 162
Pitanje
How do you solve a factored polynomial inequality reliably?
Odgovor
Find the zeros, split the number line into intervals, and test each interval's sign. Include a zero only when equality is allowed.
Kartica 163
Pitanje
Does happening first prove causation?
Odgovor
No. The timing may fit a causal story, but coincidence or another cause can still explain the later event.
Kartica 164
Pitanje
How can you spot an unsupported cross-source conclusion?
Odgovor
Identify the bridge between evidence and conclusion. If the sources never establish that bridge, the conclusion needs an assumption.
Kartica 165
Pitanje
What do 0 = 0 and 0 = 5 mean after simplifying an equation?
Odgovor
0 = 0 means every allowed value is a solution; 0 = 5 means there is no solution.
Kartica 166
Pitanje
What should you verify before comparing figures from different sources?
Odgovor
Common units and denominators. Convert first, then compare the same quantity on the same basis.
Kartica 167
Pitanje
How do you interpret |x − a| < r when r is positive?
Odgovor
x is within r units of a: a − r < x < a + r.
Kartica 168
Pitanje
What can a larger sample improve?
Odgovor
Precision, if the sampling method is sound. A huge biased sample can still give a confidently wrong picture of the population.
Kartica 169
Pitanje
How should a cross-source recommendation be evaluated?
Odgovor
Apply the stated decision rule to the combined evidence. Do not substitute a personal preference for the rule.
Kartica 170
Pitanje
If a worker finishes one job in t hours, what is the worker's hourly rate?
Odgovor
1/t of the job per hour.
Kartica 171
Pitanje
What can an average hide?
Odgovor
The distribution. Two groups can share an average while differing sharply in range, concentration, or the number of extreme values.
Kartica 172
Pitanje
What should you confirm before submitting a Multi-Source Reasoning answer?
Odgovor
That every required part is supported by the correct source and scope. One unsupported component can invalidate the whole decision.
Kartica 173
Pitanje
How do you find the amount of a pure component in a mixture?
Odgovor
Concentration × total mixture amount. A 30% solution with volume 20 contains 0.30 × 20 = 6 units of the component.
Kartica 174
Pitanje
What role does a concession usually play?
Odgovor
It acknowledges a point that weighs against the conclusion, then answers that point or limits its relevance. Don't mistake the conceded claim for the argument's main conclusion.
Kartica 175
Pitanje
When can an apparent cross-source discrepancy be resolved?
Odgovor
When a stated difference in scope or method explains both figures. If no bridge is given, keep the conflict open.
Kartica 176
Pitanje
What is the two-set overlap formula?
Odgovor
In A or B = in A + in B − in both. Subtract the overlap because it was counted twice.
Kartica 177
Pitanje
What should you identify first in Table Analysis?
Odgovor
The row unit, column definitions, and any notes. This establishes what one record and each value represent.
Kartica 178
Pitanje
What is the fundamental counting principle?
Odgovor
Multiply the choices at successive stages when each stage has a fixed number of available choices.
Kartica 179
Pitanje
Why distinguish relative change from absolute change?
Odgovor
Relative change is the percentage change; absolute change is the amount added or lost. A 50% rise from 2 adds 1, while a 10% rise from 1,000 adds 100.
Kartica 180
Pitanje
How should a table filter be translated?
Odgovor
Turn it into an exact inclusion rule. Apply every condition before counting or comparing rows.
Kartica 181
Pitanje
For equally likely outcomes, what is the basic probability formula?
Odgovor
Favorable outcomes divided by total possible outcomes.
Kartica 182
Pitanje
What makes a proposed causal mechanism useful?
Odgovor
It explains how the cause could produce the effect. A plausible, evidence-backed mechanism strengthens the causal link.
Kartica 183
Pitanje
How do you find the median?
Odgovor
Order the values and take the middle value; for an even count, average the two middle values.
Kartica 184
Pitanje
How should numeric values be sorted?
Odgovor
By numerical value, not digit order. For example, 12 comes after 9 in ascending order.
Kartica 185
Pitanje
What is missed when evidence includes only successful cases?
Odgovor
The failures. Studying only surviving firms can make a strategy look safer or more effective than it is.
Kartica 186
Pitanje
Two machines have stated constant rates of 1/3 and 1/5 job per hour and operate simultaneously without interference. May their rates be added?
Odgovor
Yes. The stated rates are constant and the machines do not interfere, so their combined rate is 1/3 + 1/5 = 8/15 job per hour.
Kartica 187
Pitanje
How should a table ratio be built when filters are involved?
Odgovor
Derive the numerator and denominator separately from the question, then apply each filter only where it is relevant. Do not automatically filter both quantities or default to all rows.
Kartica 188
Pitanje
What quantity is conserved when two solutions are mixed without loss?
Odgovor
The amount of the pure component. Set the sum of the starting component amounts equal to the final component amount.
Kartica 189
Pitanje
When may table rows be added directly?
Odgovor
Only when they are disjoint parts of the same measure and use compatible units. Overlapping groups would be double-counted.
Kartica 190
Pitanje
What does n! mean for a positive integer n?
Odgovor
The product of the positive integers from 1 through n.
Kartica 191
Pitanje
Where is the argument's logical gap?
Odgovor
Between the evidence and the conclusion. State what must connect them without merely repeating either side.
Kartica 192
Pitanje
How do you find the number in neither of two sets?
Odgovor
Subtract the number in the union from the total population.
Kartica 193
Pitanje
How should rates from table groups be combined?
Odgovor
Divide the total numerator by the total denominator. Weight a group rate by its group size only when that size is the rate's denominator.
Kartica 194
Pitanje
What is wrong with moving from some cases to all cases?
Odgovor
The conclusion is broader than the evidence. Evidence that some members have a trait doesn't show that every member does.
Kartica 195
Pitanje
When should you use a permutation?
Odgovor
When selecting and arranging items and order matters. The number of ordered selections of r from n distinct items is n!/(n − r)!.
Kartica 196
Pitanje
Why does table granularity matter?
Odgovor
A row-level fact may disappear or change after aggregation. Match the claim to the table’s level of detail.
Kartica 197
Pitanje
How do you find the probability that an event does not occur?
Odgovor
1 − P(event). This is often the quickest route for “at least one” questions.
Kartica 198
Pitanje
Why does a comparable control group help test causation?
Odgovor
It shows what happened without the suspected cause. If the groups differ mainly in that factor, the result is harder to explain another way.
Kartica 199
Pitanje
How should missing table entries be treated?
Odgovor
As unknown unless the notes define another meaning. Exclude or include them only as the question directs.
Kartica 200
Pitanje
What is the mode of a data set?
Odgovor
A mode is any value with the greatest frequency. Under the no-mode convention, there is no mode only when at least two distinct values all have equal frequency.
Kartica 201
Pitanje
What makes a table comparison valid?
Odgovor
The values must have compatible measures, units, periods, populations, and definitions. Normalize only validly convertible differences; reject differences in population, period, or definition that cannot be reconciled.
Kartica 202
Pitanje
What should you check when a prediction extends a past pattern?
Odgovor
Whether the conditions behind the past pattern will continue. A trend alone doesn't show that its causes will remain in place.
Kartica 203
Pitanje
How should a drain or other undoing process enter a work-rate equation?
Odgovor
As a negative rate. Add productive rates and subtract rates that reverse the work.
Kartica 204
Pitanje
How can you avoid losing your place while scanning a table?
Odgovor
Evaluate one condition at a time and mark qualifying rows mentally or on the scratchpad. Count only after the final filter.
Kartica 205
Pitanje
Can evidence that an outcome is possible show it is likely?
Odgovor
No. Possibility only shows that an outcome can occur; probability requires evidence about how likely it is.
Kartica 206
Pitanje
What correction is needed when counting the union of three sets?
Odgovor
Add the three individual counts, subtract all three pairwise overlaps, then add the triple overlap back once.
Kartica 207
Pitanje
When does a filtered table support a decision?
Odgovor
When the qualifying rows satisfy the stated rule. Keep filtering, calculation, and decision as separate steps.
Kartica 208
Pitanje
When should you use a combination?
Odgovor
When selecting items and order does not matter. The number of selections of r from n distinct items is n!/[r!(n − r)!].
Kartica 209
Pitanje
What must support a recommendation?
Odgovor
A link from the proposed action to the stated goal. The argument also needs the action to be feasible and free of costs that defeat the goal.
Kartica 210
Pitanje
How do AND and OR change a table filter?
Odgovor
AND requires every condition; OR requires at least one. Parenthesize mixed rules before scanning rows.
Kartica 211
Pitanje
How do you find the probability that independent events both occur?
Odgovor
Multiply their probabilities: P(A and B) = P(A) × P(B).
Kartica 212
Pitanje
What can make an alphabetical sort misleading?
Odgovor
Labels may contain categories or embedded numbers. Confirm whether the column is text, numeric, or chronological.
Kartica 213
Pitanje
What kind of fact most directly strengthens an argument?
Odgovor
A fact that supports the missing link between evidence and conclusion. Merely repeating a premise adds little.
Kartica 214
Pitanje
What is the range of a data set?
Odgovor
Maximum value minus minimum value.
Kartica 215
Pitanje
What should you check at a filter cutoff?
Odgovor
Whether the boundary is inclusive. “At least 40” includes 40; “more than 40” does not.
Kartica 216
Pitanje
A train covers 150 miles in 3 hours at a constant rate. What is its rate?
Odgovor
50 miles per hour. Rearrange distance = rate × time to get rate = 150 ÷ 3.
Kartica 217
Pitanje
What is the most direct way to weaken an argument?
Odgovor
Undermine a necessary assumption connecting the evidence to the conclusion. The premises can remain true while the conclusion loses support.
Kartica 218
Pitanje
What does a tie in the sorted column imply?
Odgovor
The tied rows share rank on that measure. Their display order does not create a performance difference.
Kartica 219
Pitanje
How do you identify a useful evaluation question?
Odgovor
Test whether opposite answers would push the argument in opposite directions. If both answers leave the conclusion unchanged, the question isn't useful.
Kartica 220
Pitanje
What should you identify first in Graphics Interpretation?
Odgovor
The chart type and what each visual encoding represents. Bars, lines, areas, and points support different readings.
Kartica 221
Pitanje
How do repeated identical items affect arrangement counts?
Odgovor
For n total items, divide n! by the factorial of each repeated count. Identical items do not create new arrangements when swapped.
Kartica 222
Pitanje
What should you read before estimating a plotted value?
Odgovor
Both axis labels, units, and category order. Position has meaning only after the axes are understood.
Kartica 223
Pitanje
How do you test whether a statement is a necessary assumption?
Odgovor
Negate it. If that negation seriously damages the argument, the original statement was necessary.
Kartica 224
Pitanje
How do you find the probability that one of two mutually exclusive events occurs?
Odgovor
Add their probabilities: P(A or B) = P(A) + P(B). Their overlap is zero.
Kartica 225
Pitanje
What should you verify in a chart legend?
Odgovor
Which color, shape, or line maps to each series. Similar styling can otherwise swap the groups in your interpretation.
Kartica 226
Pitanje
What does standard deviation measure?
Odgovor
How spread out values are around the mean. Greater dispersion means a larger standard deviation.
Kartica 227
Pitanje
What standard should an inference meet?
Odgovor
It must follow from the given statements, without extra assumptions. Choose the modest claim the evidence guarantees.
Kartica 228
Pitanje
What does a segment’s share depend on?
Odgovor
The correct whole. A category’s share of one region may differ from its share of the full dataset.
Kartica 229
Pitanje
For motion along the same line, when do you add or subtract two speeds to get relative speed?
Odgovor
Add the speeds for opposite directions; subtract the smaller speed from the larger for the same direction.
Kartica 230
Pitanje
What must a paradox explanation accomplish?
Odgovor
Make both surprising facts plausible at the same time. Rejecting either stated fact doesn't resolve the tension.
Kartica 231
Pitanje
How is a segment in a stacked bar measured?
Odgovor
Subtract its lower boundary from its upper boundary. The upper endpoint alone is cumulative, not the segment value.
Kartica 232
Pitanje
Eight students average 70 and twelve students average 80. What is the combined mean?
Odgovor
- The group sizes are the weights: (8 × 70 + 12 × 80) ÷ 20 = 76.
Kartica 233
Pitanje
What is the difference between a graph’s level and its rate of change?
Odgovor
Level is the plotted value; rate of change is the slope. A high line can still be falling.
Kartica 234
Pitanje
How should you describe a statement's role in an argument?
Odgovor
Describe what it does, not just what it says. It may support the conclusion, present an objection, answer that objection, or illustrate a principle.
Kartica 235
Pitanje
What is P(A given B)?
Odgovor
P(A and B) / P(B), provided P(B) > 0. Restrict the sample space to outcomes in B.
Kartica 236
Pitanje
How should slope be compared across a graph?
Odgovor
Use change in vertical value divided by change in horizontal value. Visual steepness is reliable only on the same scales.
Kartica 237
Pitanje
A driver covers equal distances at 30 mph and 60 mph. Is the average speed 45 mph?
Odgovor
No. Using 60 miles for each leg gives 120 miles in 3 hours, so the average speed is 40 mph.
Kartica 238
Pitanje
What should you identify first when evaluating a plan?
Odgovor
The plan's exact goal and success measure. A proposal can produce benefits yet still fail its stated objective.
Kartica 239
Pitanje
What does a trend in a scatterplot establish?
Odgovor
An association in the displayed data. It does not by itself establish causation or predict every individual point.
Kartica 240
Pitanje
How can you strengthen a causal explanation?
Odgovor
Rule out a credible alternative cause, support the proposed mechanism, or show the effect changes when the proposed cause changes.
Kartica 241
Pitanje
How can an outlier affect a graphical trend?
Odgovor
It can pull a summary line or average away from the main cluster. Check whether the claim concerns all points or the typical pattern.
Kartica 242
Pitanje
Why do probabilities usually change when sampling without replacement?
Odgovor
The sample space changes after each draw. Update both the favorable count and the total before multiplying conditional probabilities.
Kartica 243
Pitanje
One value in an n-value set increases by d. How does the mean change?
Odgovor
It increases by d/n because the total rises by d while the count stays fixed.
Kartica 244
Pitanje
When does a counterexample weaken a claim?
Odgovor
When the claim requires the counterexample not to exist. One genuine exception can defeat an absolute claim, but may barely affect a modest one.
Kartica 245
Pitanje
What is the parity of the sum of two odd integers?
Odgovor
Even. Each odd integer is one more than an even integer, so the two extra ones add to 2.
Kartica 246
Pitanje
What can an aggregate graph hide?
Odgovor
Differences among subgroups or periods. A stable total can coexist with large offsetting changes inside it.
Kartica 247
Pitanje
When is interpolation reasonable on a graph?
Odgovor
When the graph implies continuity between nearby points. Do not interpolate across separate categories.
Kartica 248
Pitanje
What makes information relevant to evaluating an argument?
Odgovor
It bears on the uncertain link the conclusion depends on. Interesting facts about the topic may still be logically irrelevant.
Kartica 249
Pitanje
How precise should a value read from a graph be?
Odgovor
Only as precise as the scale supports. Use a defensible interval when the mark falls between ticks.
Kartica 250
Pitanje
Must a necessary assumption prove the conclusion?
Odgovor
No. It only has to be required for the argument to work; it need not be enough to establish the conclusion on its own.
Kartica 251
Pitanje
How do you multiply positive numbers written in scientific notation?
Odgovor
Multiply the coefficients, add the powers of 10, then adjust the coefficient to be at least 1 and less than 10.
Kartica 252
Pitanje
How should a graph-based decision be made?
Odgovor
Translate the visual into values or bounds, then apply the stated rule. Do not decide from appearance alone.
Kartica 253
Pitanje
When is backsolving from answer choices especially useful?
Odgovor
When the choices are concrete values and direct algebra is slower than testing them in the original conditions.
Kartica 254
Pitanje
How can axis scale distort a visual impression?
Odgovor
Unequal intervals or a truncated baseline can magnify or compress differences. Use tick values, not apparent distance alone.
Kartica 255
Pitanje
When should you combine two statements for an inference?
Odgovor
When they share a term or relationship that creates a guaranteed consequence. Don't combine them through an unstated causal or statistical link.
Kartica 256
Pitanje
When is a product of integers odd?
Odgovor
Only when every factor is odd. One even factor makes the entire product even.
Kartica 257
Pitanje
What often resolves two apparently conflicting results?
Odgovor
A hidden difference in group, time, measurement, or conditions. The results may describe different slices of the situation.
Kartica 258
Pitanje
How should equal distances on a logarithmic axis be interpreted?
Odgovor
As equal multiplicative changes, not equal absolute changes. Read the labeled values before comparing gaps.
Kartica 259
Pitanje
Why start with a middle answer choice when backsolving ordered options?
Odgovor
Its result often eliminates half the choices at once when the relationship is monotonic.
Kartica 260
Pitanje
What makes a Two-Part Analysis response complete?
Odgovor
Both selections must satisfy their own column prompts under the same stem. Treat the pair as one submitted response.
Kartica 261
Pitanje
What is an analogy doing when it supports a claim?
Odgovor
It argues that because two cases share relevant features, a result or principle from one likely applies to the other.
Kartica 262
Pitanje
How do you represent three consecutive odd integers?
Odgovor
n, n + 2, and n + 4, where n is an odd integer.
Kartica 263
Pitanje
What should you identify before solving Two-Part Analysis?
Odgovor
The role of each column. One may ask for a condition while the other asks for a consequence or decision.
Kartica 264
Pitanje
What values should you test first in a claim about an unspecified number?
Odgovor
Test allowed categories that may behave differently: positive, negative, zero, fractional, and boundary values.
Kartica 265
Pitanje
How can an unchanged bottleneck defeat a plan?
Odgovor
Improving a nonlimiting step won't improve the final outcome if another constraint still controls it. Faster ordering doesn't help when production is already full.
Kartica 266
Pitanje
How does the shared stem affect the two parts?
Odgovor
Its definitions and constraints apply to both. Keep them fixed while testing each column’s requirement.
Kartica 267
Pitanje
How do you count the positive divisors of an integer greater than 1 from its prime factorization?
Odgovor
Add 1 to each prime exponent, then multiply those results.
Kartica 268
Pitanje
In Two-Part Analysis, must the two selected entries be the same?
Odgovor
In the current format, the two selected entries may be the same or different. A linkage in the stem determines whether you must reason through them jointly, not whether their values match.
Kartica 269
Pitanje
What makes evidence for a general claim strong?
Odgovor
It should be relevant and reliable and, if case-based, come from representative cases. More evidence isn't automatically better evidence.
Kartica 270
Pitanje
How do you factor a difference of squares?
Odgovor
Use x² − y² = (x − y)(x + y).
Kartica 271
Pitanje
When should the two Two-Part Analysis selections be solved together?
Odgovor
When one shared relationship constrains both. Test candidate pairs against that relationship instead of solving isolated fragments.
Kartica 272
Pitanje
How can one counterexample evaluate a universal claim?
Odgovor
One valid counterexample disproves a claim that is supposed to hold for every allowed value.
Kartica 273
Pitanje
How does an alternative explanation weaken a conclusion?
Odgovor
It shows that the evidence can be true without the proposed explanation being true. The alternative must account for the same result.
Kartica 274
Pitanje
In Two-Part Analysis, how can one column help solve the other?
Odgovor
A valid selection can narrow the remaining candidates when the parts share a constraint. Recheck the final pair in both columns.
Kartica 275
Pitanje
How do you test whether x² + bx + c factors into integer binomials?
Odgovor
Look for integers r and s with r + s = b and rs = c. If they exist, the factorization is (x + r)(x + s).
Kartica 276
Pitanje
Which unknown should you evaluate first in a plan argument?
Odgovor
A condition that could make the plan achieve or miss its goal. Focus on feasibility, response, costs, and side effects tied to that goal.
Kartica 277
Pitanje
How should a trade-off between two measures be evaluated?
Odgovor
Apply the stated priorities or limits. An option is better only relative to the rule, not because one measure is largest.
Kartica 278
Pitanje
How can estimation screen answer choices before exact calculation?
Odgovor
Approximate the expression's magnitude, then eliminate choices that are far too large or too small.
Kartica 279
Pitanje
In a constrained-decision Two-Part Analysis problem, what should you check before comparing candidates?
Odgovor
Check every hard constraint first. Discard any option that breaks a required limit, then compare only the feasible candidates.
Kartica 280
Pitanje
What does a defensive assumption do?
Odgovor
It rules out a threat that would break the argument. For example, a revenue plan may assume that its added costs won't exceed the new revenue.
Kartica 281
Pitanje
What restriction applies when a variable appears in a denominator?
Odgovor
Exclude every value that makes the denominator zero.
Kartica 282
Pitanje
How does an objective differ from a constraint?
Odgovor
A constraint determines what is allowed; an objective ranks the allowed options. Apply them in that order.
Kartica 283
Pitanje
Which quick checks catch many Quant answer errors?
Odgovor
Check the sign, units, allowed range, and rough size against the question's conditions.
Kartica 284
Pitanje
What inference is safe from a statement about most members?
Odgovor
More than half have the stated trait. You can't infer that all do, that any particular member does, or that most have another trait.
Kartica 285
Pitanje
How should a two-part threshold rule be handled?
Odgovor
Translate each threshold with the correct inequality, including its boundary. Then test both selected values against it.
Kartica 286
Pitanje
Where can one negative sign appear in a fraction without changing its value?
Odgovor
Before the fraction, in the numerator, or in the denominator: −(a/b) = (−a)/b = a/(−b), provided b ≠ 0.
Kartica 287
Pitanje
How does an argument choose between competing explanations?
Odgovor
It presents evidence that one explanation handles better than the others, often by ruling out a rival prediction.
Kartica 288
Pitanje
What is an efficient way to handle two linked algebraic targets?
Odgovor
Express both in terms of one variable or invariant. Evaluate candidate values only after the relationship is clear.
Kartica 289
Pitanje
How do you solve x² = c over the real numbers?
Odgovor
If c > 0, x = ±√c; if c = 0, x = 0; if c < 0, there is no real solution.
Kartica 290
Pitanje
What should you check when two selected quantities form a ratio?
Odgovor
Order and scale. The ratio A:B is not interchangeable with B:A, and proportional pairs may all fit.
Kartica 291
Pitanje
How does a positive proper fraction compare with 1?
Odgovor
It is less than 1 because its numerator is smaller than its denominator.
Kartica 292
Pitanje
Which side effects matter when evaluating a plan?
Odgovor
Effects that change the plan's net result or work against its goal. A small unrelated inconvenience usually doesn't matter.
Kartica 293
Pitanje
How should a two-part logical claim be tested?
