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.

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

Kort 151
Spørsmål
When can you use the zero-product property?
Svar
After rewriting a product equal to zero. If (x − 2)(x + 5) = 0, then x = 2 or x = −5.
Kort 152
Spørsmål
How does an inference differ from a stated fact?
Svar
A fact appears directly in a source; an inference must follow from the sources without an extra assumption.
Kort 153
Spørsmål
Does a higher percentage by itself prove a higher count?
Svar
No. The underlying totals matter. Twenty percent of 1,000 is more than fifty percent of 100.
Kort 154
Spørsmål
What does an “or” compound inequality require?
Svar
The union of the solution sets. A value may satisfy either condition or both.
Kort 155
Spørsmål
What does a blank or omitted value establish?
Svar
Only that the value is not provided. It does not establish zero, no change, or failure.
Kort 156
Spørsmål
How do you recognize an intermediate conclusion?
Svar
It is supported by one claim and supports another. It acts as both a conclusion and a premise in the same argument.
Kort 157
Spørsmål
What should you do before writing equations for a two-quantity word problem?
Svar
Define each variable with its unit, then translate one independent relationship per equation.
Kort 158
Spørsmål
Why should cross-source events be placed in time order?
Svar
Sequence separates prior conditions from later outcomes and prevents using future information as an earlier cause.
Kort 159
Spørsmål
When should candidate solutions be checked in the original equation?
Svar
Always after a step that may introduce solutions, especially squaring both sides or clearing variable denominators.
Kort 160
Spørsmål
How can switching from one measured outcome to another create a gap?
Svar
Evidence about one metric may not support a conclusion about another. More website visits, for example, don't by themselves mean more sales.
Kort 161
Spørsmål
What makes a source relevant to a claim?
Svar
It supplies evidence for a required link in the claim. Related background alone is not enough.
Kort 162
Spørsmål
How do you solve a factored polynomial inequality reliably?
Svar
Find the zeros, split the number line into intervals, and test each interval's sign. Include a zero only when equality is allowed.
Kort 163
Spørsmål
Does happening first prove causation?
Svar
No. The timing may fit a causal story, but coincidence or another cause can still explain the later event.
Kort 164
Spørsmål
How can you spot an unsupported cross-source conclusion?
Svar
Identify the bridge between evidence and conclusion. If the sources never establish that bridge, the conclusion needs an assumption.
Kort 165
Spørsmål
What do 0 = 0 and 0 = 5 mean after simplifying an equation?
Svar
0 = 0 means every allowed value is a solution; 0 = 5 means there is no solution.
Kort 166
Spørsmål
What should you verify before comparing figures from different sources?
Svar
Common units and denominators. Convert first, then compare the same quantity on the same basis.
Kort 167
Spørsmål
How do you interpret |x − a| < r when r is positive?
Svar
x is within r units of a: a − r < x < a + r.
Kort 168
Spørsmål
What can a larger sample improve?
Svar
Precision, if the sampling method is sound. A huge biased sample can still give a confidently wrong picture of the population.
Kort 169
Spørsmål
How should a cross-source recommendation be evaluated?
Svar
Apply the stated decision rule to the combined evidence. Do not substitute a personal preference for the rule.
Kort 170
Spørsmål
If a worker finishes one job in t hours, what is the worker's hourly rate?
Svar
1/t of the job per hour.
Kort 171
Spørsmål
What can an average hide?
Svar
The distribution. Two groups can share an average while differing sharply in range, concentration, or the number of extreme values.
Kort 172
Spørsmål
What should you confirm before submitting a Multi-Source Reasoning answer?
Svar
That every required part is supported by the correct source and scope. One unsupported component can invalidate the whole decision.
Kort 173
Spørsmål
How do you find the amount of a pure component in a mixture?
Svar
Concentration × total mixture amount. A 30% solution with volume 20 contains 0.30 × 20 = 6 units of the component.
Kort 174
Spørsmål
What role does a concession usually play?
Svar
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.
Kort 175
Spørsmål
When can an apparent cross-source discrepancy be resolved?
Svar
When a stated difference in scope or method explains both figures. If no bridge is given, keep the conflict open.
Kort 176
Spørsmål
What is the two-set overlap formula?
Svar
In A or B = in A + in B − in both. Subtract the overlap because it was counted twice.
Kort 177
Spørsmål
What should you identify first in Table Analysis?
Svar
The row unit, column definitions, and any notes. This establishes what one record and each value represent.
Kort 178
Spørsmål
What is the fundamental counting principle?
Svar
Multiply the choices at successive stages when each stage has a fixed number of available choices.
Kort 179
Spørsmål
Why distinguish relative change from absolute change?
Svar
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.
Kort 180
Spørsmål
How should a table filter be translated?
Svar
Turn it into an exact inclusion rule. Apply every condition before counting or comparing rows.
Kort 181
Spørsmål
For equally likely outcomes, what is the basic probability formula?
Svar
Favorable outcomes divided by total possible outcomes.
Kort 182
Spørsmål
What makes a proposed causal mechanism useful?
Svar
It explains how the cause could produce the effect. A plausible, evidence-backed mechanism strengthens the causal link.
Kort 183
Spørsmål
How do you find the median?
Svar
Order the values and take the middle value; for an even count, average the two middle values.
Kort 184
Spørsmål
How should numeric values be sorted?
Svar
By numerical value, not digit order. For example, 12 comes after 9 in ascending order.
Kort 185
Spørsmål
What is missed when evidence includes only successful cases?
Svar
The failures. Studying only surviving firms can make a strategy look safer or more effective than it is.
Kort 186
Spørsmål
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?
Svar
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.
Kort 187
Spørsmål
How should a table ratio be built when filters are involved?
Svar
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.
Kort 188
Spørsmål
What quantity is conserved when two solutions are mixed without loss?
Svar
The amount of the pure component. Set the sum of the starting component amounts equal to the final component amount.
Kort 189
Spørsmål
When may table rows be added directly?
Svar
Only when they are disjoint parts of the same measure and use compatible units. Overlapping groups would be double-counted.
Kort 190
Spørsmål
What does n! mean for a positive integer n?
Svar
The product of the positive integers from 1 through n.
Kort 191
Spørsmål
Where is the argument's logical gap?
Svar
Between the evidence and the conclusion. State what must connect them without merely repeating either side.
Kort 192
Spørsmål
How do you find the number in neither of two sets?
Svar
Subtract the number in the union from the total population.
Kort 193
Spørsmål
How should rates from table groups be combined?
Svar
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.
Kort 194
Spørsmål
What is wrong with moving from some cases to all cases?
Svar
The conclusion is broader than the evidence. Evidence that some members have a trait doesn't show that every member does.
Kort 195
Spørsmål
When should you use a permutation?
Svar
When selecting and arranging items and order matters. The number of ordered selections of r from n distinct items is n!/(n − r)!.
Kort 196
Spørsmål
Why does table granularity matter?
Svar
A row-level fact may disappear or change after aggregation. Match the claim to the table’s level of detail.
Kort 197
Spørsmål
How do you find the probability that an event does not occur?
Svar
1 − P(event). This is often the quickest route for “at least one” questions.
Kort 198
Spørsmål
Why does a comparable control group help test causation?
Svar
It shows what happened without the suspected cause. If the groups differ mainly in that factor, the result is harder to explain another way.
Kort 199
Spørsmål
How should missing table entries be treated?
Svar
As unknown unless the notes define another meaning. Exclude or include them only as the question directs.
Kort 200
Spørsmål
What is the mode of a data set?
Svar
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.
Kort 201
Spørsmål
What makes a table comparison valid?
Svar
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.
Kort 202
Spørsmål
What should you check when a prediction extends a past pattern?
Svar
Whether the conditions behind the past pattern will continue. A trend alone doesn't show that its causes will remain in place.
Kort 203
Spørsmål
How should a drain or other undoing process enter a work-rate equation?
Svar
As a negative rate. Add productive rates and subtract rates that reverse the work.
Kort 204
Spørsmål
How can you avoid losing your place while scanning a table?
Svar
Evaluate one condition at a time and mark qualifying rows mentally or on the scratchpad. Count only after the final filter.
Kort 205
Spørsmål
Can evidence that an outcome is possible show it is likely?
Svar
No. Possibility only shows that an outcome can occur; probability requires evidence about how likely it is.
Kort 206
Spørsmål
What correction is needed when counting the union of three sets?
Svar
Add the three individual counts, subtract all three pairwise overlaps, then add the triple overlap back once.
Kort 207
Spørsmål
When does a filtered table support a decision?
Svar
When the qualifying rows satisfy the stated rule. Keep filtering, calculation, and decision as separate steps.
Kort 208
Spørsmål
When should you use a combination?
Svar
When selecting items and order does not matter. The number of selections of r from n distinct items is n!/[r!(n − r)!].
Kort 209
Spørsmål
What must support a recommendation?
Svar
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.
Kort 210
Spørsmål
How do AND and OR change a table filter?
Svar
AND requires every condition; OR requires at least one. Parenthesize mixed rules before scanning rows.
Kort 211
Spørsmål
How do you find the probability that independent events both occur?
Svar
Multiply their probabilities: P(A and B) = P(A) × P(B).
Kort 212
Spørsmål
What can make an alphabetical sort misleading?
Svar
Labels may contain categories or embedded numbers. Confirm whether the column is text, numeric, or chronological.
Kort 213
Spørsmål
What kind of fact most directly strengthens an argument?
Svar
A fact that supports the missing link between evidence and conclusion. Merely repeating a premise adds little.
Kort 214
Spørsmål
What is the range of a data set?
Svar
Maximum value minus minimum value.
Kort 215
Spørsmål
What should you check at a filter cutoff?
Svar
Whether the boundary is inclusive. “At least 40” includes 40; “more than 40” does not.
Kort 216
Spørsmål
A train covers 150 miles in 3 hours at a constant rate. What is its rate?
Svar
50 miles per hour. Rearrange distance = rate × time to get rate = 150 ÷ 3.
Kort 217
Spørsmål
What is the most direct way to weaken an argument?
Svar
Undermine a necessary assumption connecting the evidence to the conclusion. The premises can remain true while the conclusion loses support.
Kort 218
Spørsmål
What does a tie in the sorted column imply?
Svar
The tied rows share rank on that measure. Their display order does not create a performance difference.
Kort 219
Spørsmål
How do you identify a useful evaluation question?
Svar
Test whether opposite answers would push the argument in opposite directions. If both answers leave the conclusion unchanged, the question isn't useful.
Kort 220
Spørsmål
What should you identify first in Graphics Interpretation?
Svar
The chart type and what each visual encoding represents. Bars, lines, areas, and points support different readings.
Kort 221
Spørsmål
How do repeated identical items affect arrangement counts?
Svar
For n total items, divide n! by the factorial of each repeated count. Identical items do not create new arrangements when swapped.
Kort 222
Spørsmål
What should you read before estimating a plotted value?
Svar
Both axis labels, units, and category order. Position has meaning only after the axes are understood.
Kort 223
Spørsmål
How do you test whether a statement is a necessary assumption?
Svar
Negate it. If that negation seriously damages the argument, the original statement was necessary.
Kort 224
Spørsmål
How do you find the probability that one of two mutually exclusive events occurs?
Svar
Add their probabilities: P(A or B) = P(A) + P(B). Their overlap is zero.
Kort 225
Spørsmål
What should you verify in a chart legend?
Svar
Which color, shape, or line maps to each series. Similar styling can otherwise swap the groups in your interpretation.
Kort 226
Spørsmål
What does standard deviation measure?
Svar
How spread out values are around the mean. Greater dispersion means a larger standard deviation.
Kort 227
Spørsmål
What standard should an inference meet?
Svar
It must follow from the given statements, without extra assumptions. Choose the modest claim the evidence guarantees.
Kort 228
Spørsmål
What does a segment’s share depend on?
Svar
The correct whole. A category’s share of one region may differ from its share of the full dataset.
Kort 229
Spørsmål
For motion along the same line, when do you add or subtract two speeds to get relative speed?
Svar
Add the speeds for opposite directions; subtract the smaller speed from the larger for the same direction.
Kort 230
Spørsmål
What must a paradox explanation accomplish?
Svar
Make both surprising facts plausible at the same time. Rejecting either stated fact doesn't resolve the tension.
Kort 231
Spørsmål
How is a segment in a stacked bar measured?
Svar
Subtract its lower boundary from its upper boundary. The upper endpoint alone is cumulative, not the segment value.
Kort 232
Spørsmål
Eight students average 70 and twelve students average 80. What is the combined mean?
Svar
- The group sizes are the weights: (8 × 70 + 12 × 80) ÷ 20 = 76.
Kort 233
Spørsmål
What is the difference between a graph’s level and its rate of change?
Svar
Level is the plotted value; rate of change is the slope. A high line can still be falling.
Kort 234
Spørsmål
How should you describe a statement's role in an argument?
Svar
Describe what it does, not just what it says. It may support the conclusion, present an objection, answer that objection, or illustrate a principle.
Kort 235
Spørsmål
What is P(A given B)?
Svar
P(A and B) / P(B), provided P(B) > 0. Restrict the sample space to outcomes in B.
Kort 236
Spørsmål
How should slope be compared across a graph?
Svar
Use change in vertical value divided by change in horizontal value. Visual steepness is reliable only on the same scales.
Kort 237
Spørsmål
A driver covers equal distances at 30 mph and 60 mph. Is the average speed 45 mph?
Svar
No. Using 60 miles for each leg gives 120 miles in 3 hours, so the average speed is 40 mph.
Kort 238
Spørsmål
What should you identify first when evaluating a plan?
Svar
The plan's exact goal and success measure. A proposal can produce benefits yet still fail its stated objective.
Kort 239
Spørsmål
What does a trend in a scatterplot establish?
Svar
An association in the displayed data. It does not by itself establish causation or predict every individual point.
Kort 240
Spørsmål
How can you strengthen a causal explanation?
Svar
Rule out a credible alternative cause, support the proposed mechanism, or show the effect changes when the proposed cause changes.
Kort 241
Spørsmål
How can an outlier affect a graphical trend?
Svar
It can pull a summary line or average away from the main cluster. Check whether the claim concerns all points or the typical pattern.
Kort 242
Spørsmål
Why do probabilities usually change when sampling without replacement?
Svar
The sample space changes after each draw. Update both the favorable count and the total before multiplying conditional probabilities.
Kort 243
Spørsmål
One value in an n-value set increases by d. How does the mean change?
Svar
It increases by d/n because the total rises by d while the count stays fixed.
Kort 244
Spørsmål
When does a counterexample weaken a claim?
Svar
When the claim requires the counterexample not to exist. One genuine exception can defeat an absolute claim, but may barely affect a modest one.
Kort 245
Spørsmål
What is the parity of the sum of two odd integers?
Svar
Even. Each odd integer is one more than an even integer, so the two extra ones add to 2.
Kort 246
Spørsmål
What can an aggregate graph hide?
Svar
Differences among subgroups or periods. A stable total can coexist with large offsetting changes inside it.
Kort 247
Spørsmål
When is interpolation reasonable on a graph?
Svar
When the graph implies continuity between nearby points. Do not interpolate across separate categories.
Kort 248
Spørsmål
What makes information relevant to evaluating an argument?
Svar
It bears on the uncertain link the conclusion depends on. Interesting facts about the topic may still be logically irrelevant.
Kort 249
Spørsmål
How precise should a value read from a graph be?
Svar
Only as precise as the scale supports. Use a defensible interval when the mark falls between ticks.
Kort 250
Spørsmål
Must a necessary assumption prove the conclusion?
Svar
No. It only has to be required for the argument to work; it need not be enough to establish the conclusion on its own.
Kort 251
Spørsmål
How do you multiply positive numbers written in scientific notation?
Svar
Multiply the coefficients, add the powers of 10, then adjust the coefficient to be at least 1 and less than 10.
Kort 252
Spørsmål
How should a graph-based decision be made?
Svar
Translate the visual into values or bounds, then apply the stated rule. Do not decide from appearance alone.
Kort 253
Spørsmål
When is backsolving from answer choices especially useful?
Svar
When the choices are concrete values and direct algebra is slower than testing them in the original conditions.
Kort 254
Spørsmål
How can axis scale distort a visual impression?
Svar
Unequal intervals or a truncated baseline can magnify or compress differences. Use tick values, not apparent distance alone.
Kort 255
Spørsmål
When should you combine two statements for an inference?
Svar
When they share a term or relationship that creates a guaranteed consequence. Don't combine them through an unstated causal or statistical link.
Kort 256
Spørsmål
When is a product of integers odd?
Svar
Only when every factor is odd. One even factor makes the entire product even.
Kort 257
Spørsmål
What often resolves two apparently conflicting results?
Svar
A hidden difference in group, time, measurement, or conditions. The results may describe different slices of the situation.
Kort 258
Spørsmål
How should equal distances on a logarithmic axis be interpreted?
Svar
As equal multiplicative changes, not equal absolute changes. Read the labeled values before comparing gaps.
Kort 259
Spørsmål
Why start with a middle answer choice when backsolving ordered options?
Svar
Its result often eliminates half the choices at once when the relationship is monotonic.
Kort 260
Spørsmål
What makes a Two-Part Analysis response complete?
Svar
Both selections must satisfy their own column prompts under the same stem. Treat the pair as one submitted response.
Kort 261
Spørsmål
What is an analogy doing when it supports a claim?
Svar
It argues that because two cases share relevant features, a result or principle from one likely applies to the other.
Kort 262
Spørsmål
How do you represent three consecutive odd integers?
Svar
n, n + 2, and n + 4, where n is an odd integer.
Kort 263
Spørsmål
What should you identify before solving Two-Part Analysis?
Svar
The role of each column. One may ask for a condition while the other asks for a consequence or decision.
Kort 264
Spørsmål
What values should you test first in a claim about an unspecified number?
Svar
Test allowed categories that may behave differently: positive, negative, zero, fractional, and boundary values.
Kort 265
Spørsmål
How can an unchanged bottleneck defeat a plan?
Svar
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.
Kort 266
Spørsmål
How does the shared stem affect the two parts?
Svar
Its definitions and constraints apply to both. Keep them fixed while testing each column’s requirement.
Kort 267
Spørsmål
How do you count the positive divisors of an integer greater than 1 from its prime factorization?
Svar
Add 1 to each prime exponent, then multiply those results.
Kort 268
Spørsmål
In Two-Part Analysis, must the two selected entries be the same?
Svar
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.
Kort 269
Spørsmål
What makes evidence for a general claim strong?
Svar
It should be relevant and reliable and, if case-based, come from representative cases. More evidence isn't automatically better evidence.
Kort 270
Spørsmål
How do you factor a difference of squares?
Svar
Use x² − y² = (x − y)(x + y).
Kort 271
Spørsmål
When should the two Two-Part Analysis selections be solved together?
Svar
When one shared relationship constrains both. Test candidate pairs against that relationship instead of solving isolated fragments.
Kort 272
Spørsmål
How can one counterexample evaluate a universal claim?
Svar
One valid counterexample disproves a claim that is supposed to hold for every allowed value.
Kort 273
Spørsmål
How does an alternative explanation weaken a conclusion?
Svar
It shows that the evidence can be true without the proposed explanation being true. The alternative must account for the same result.
Kort 274
Spørsmål
In Two-Part Analysis, how can one column help solve the other?
Svar
A valid selection can narrow the remaining candidates when the parts share a constraint. Recheck the final pair in both columns.
Kort 275
Spørsmål
How do you test whether x² + bx + c factors into integer binomials?
Svar
Look for integers r and s with r + s = b and rs = c. If they exist, the factorization is (x + r)(x + s).
Kort 276
Spørsmål
Which unknown should you evaluate first in a plan argument?
Svar
A condition that could make the plan achieve or miss its goal. Focus on feasibility, response, costs, and side effects tied to that goal.
Kort 277
Spørsmål
How should a trade-off between two measures be evaluated?
Svar
Apply the stated priorities or limits. An option is better only relative to the rule, not because one measure is largest.
Kort 278
Spørsmål
How can estimation screen answer choices before exact calculation?
Svar
Approximate the expression's magnitude, then eliminate choices that are far too large or too small.
Kort 279
Spørsmål
In a constrained-decision Two-Part Analysis problem, what should you check before comparing candidates?
Svar
Check every hard constraint first. Discard any option that breaks a required limit, then compare only the feasible candidates.
Kort 280
Spørsmål
What does a defensive assumption do?
Svar
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.
Kort 281
Spørsmål
What restriction applies when a variable appears in a denominator?
Svar
Exclude every value that makes the denominator zero.
Kort 282
Spørsmål
How does an objective differ from a constraint?
Svar
A constraint determines what is allowed; an objective ranks the allowed options. Apply them in that order.
Kort 283
Spørsmål
Which quick checks catch many Quant answer errors?
Svar
Check the sign, units, allowed range, and rough size against the question's conditions.
Kort 284
Spørsmål
What inference is safe from a statement about most members?
Svar
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.
Kort 285
Spørsmål
How should a two-part threshold rule be handled?
Svar
Translate each threshold with the correct inequality, including its boundary. Then test both selected values against it.
Kort 286
Spørsmål
Where can one negative sign appear in a fraction without changing its value?
Svar
Before the fraction, in the numerator, or in the denominator: −(a/b) = (−a)/b = a/(−b), provided b ≠ 0.
Kort 287
Spørsmål
How does an argument choose between competing explanations?
Svar
It presents evidence that one explanation handles better than the others, often by ruling out a rival prediction.
Kort 288
Spørsmål
What is an efficient way to handle two linked algebraic targets?
Svar
Express both in terms of one variable or invariant. Evaluate candidate values only after the relationship is clear.
Kort 289
Spørsmål
How do you solve x² = c over the real numbers?
Svar
If c > 0, x = ±√c; if c = 0, x = 0; if c < 0, there is no real solution.
Kort 290
Spørsmål
What should you check when two selected quantities form a ratio?
Svar
Order and scale. The ratio A:B is not interchangeable with B:A, and proportional pairs may all fit.
Kort 291
Spørsmål
How does a positive proper fraction compare with 1?
Svar
It is less than 1 because its numerator is smaller than its denominator.
Kort 292
Spørsmål
Which side effects matter when evaluating a plan?
Svar
Effects that change the plan's net result or work against its goal. A small unrelated inconvenience usually doesn't matter.
Kort 293
Spørsmål
How should a two-part logical claim be tested?
Svar
Separate the condition from the conclusion, then test whether each selected statement performs the requested role.
Kort 294
Spørsmål
What is the solution pattern for |x| = a over the real numbers?
Svar
If a > 0, x = ±a; if a = 0, x = 0; if a < 0, there is no real solution.
Kort 295
Spørsmål
What unit check belongs in a two-part quantitative answer?
Svar
Confirm that each selection has the unit requested by its column. Linked values may require different conversions.
Kort 296
Spørsmål
Why does user response matter to a plan?
Svar
The plan may depend on people adopting, following, or not avoiding it. Availability alone doesn't guarantee the needed behavior.
Kort 297
Spørsmål
A response rate rises from 40% to 50%. What are the percentage-point change and the relative percent increase?
Svar
The increase is 10 percentage points and 25% relative to the original rate: (50 − 40) ÷ 40 = 0.25.
Kort 298
Spørsmål
What is the final check for Two-Part Analysis?
Svar
Read each column prompt with its chosen entry, then verify that the pair is jointly consistent with the stem.
Kort 299
Spørsmål
For real x and y, what two linear cases are equivalent to x² = y²?
Svar
x = y or x = −y.
Kort 300
Spørsmål
How should benefits and costs be compared in a plan argument?
Svar
By their net effect on the stated goal. A plan can create the intended benefit but still fail if its relevant costs are larger.
