TEAS 7 Math Practice Test

Correct Answer: B

Rationale: The correct answer is B (25). To find the range, subtract the smallest value from the largest value in a set of data. Given the options, 32 (largest) minus 7 (smallest) equals 25. Therefore, the range in the number of flights the flight attendant made is 25. Option A (20) is incorrect as it is smaller than the actual range. Option C (29) and D (32) are incorrect because they are larger than the actual range, making them invalid choices.

Correct Answer: B

Rationale: To find the approximate number of people who voted for the proposition, we multiply the town's population by the percentage that voted: 51,623 * 9.5% = 51,623 * 0.095 = 4,904. Therefore, approximately 5,000 people voted for the proposition. Choice A (3,000) is too low because 9.5% of the population would result in more voters. Choice C (7,000) is too high because it exceeds the calculation based on the given percentage. Choice D (10,000) is also too high as it overestimates the number of voters based on the percentage provided.

Correct Answer: A

Rationale: To calculate the percent increase, subtract the initial value from the final value (2219 - 1432 = 787). Then, divide the increase by the initial value and multiply by 100 to get the percentage increase [(787/1432) x 100 ≈ 55%]. Therefore, choice A (55%) is correct. Choice B (36%) is incorrect because it underestimates the actual increase. Choice C (64%) and choice D (42%) are also incorrect as they overestimate the percentage increase.

Correct Answer: C

Rationale: To find the fraction of the class that wanted to work with the elderly, we add the percentage of students who wanted to work with the elderly, which is 60%. This can be represented as 60/100, which simplifies to 3/5. Choice A (1/4) is incorrect because it represents the fraction of students who wanted to work with infants, which is 25%. Choice B (1/10) is incorrect as it represents the fraction of students who wanted to assist general practitioners, which is 10%. Choice D (1/20) is incorrect as it does not correspond to any of the given percentages in the question.

Correct Answer: C

Rationale: The correct answer is C: 29. To determine the range, subtract the smallest value from the largest value in the data set. Given the choices, 29 (C) has the widest range of values, which indicates the highest variability in the number of houses sold per year. Choices A, B, and D have smaller values, indicating less variability. Therefore, C is the correct answer as it provides the largest range, reflecting the potential difference in the number of houses sold annually.
