TEAS 7 Math Practice Test Questions

Question 1 of 5

What is the percentage equivalent of 0.0016?

Correct Answer: D

Rationale: The correct answer is D: 0.16%. To find the percentage equivalent of a decimal, we multiply the decimal by 100. So, 0.0016 x 100 = 0.16%. Choice A (16%) is incorrect because it represents the decimal as a whole number, not a percentage. Choice B (160%) is incorrect as it incorrectly multiplies the decimal by 1000 instead of 100. Choice C (1.60%) is incorrect as it incorrectly places the decimal point in the wrong position, resulting in an incorrect percentage value.

Question 2 of 5

Given the histograms shown below, which of the following statements is true?

Correct Answer: C

Rationale: The correct answer is C because in a negatively skewed distribution, the tail of the histogram extends to the left, indicating that there are more data points on the right side. In Group B, the histogram is negatively skewed, meaning it has a higher mean than Group A. Option A is incorrect because Group A is positively skewed, not negatively skewed. Option B is incorrect because Group A has a lower mean than Group B. Option D is incorrect because Group B has a higher mean than Group A due to its negatively skewed distribution.

Question 3 of 5

What is the range in the number of houses sold per year?

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.

Question 4 of 5

Approximately how many people voted for the proposition if 9.5% of the town's population of 51,623 voted for it in a municipal election?

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.

Question 5 of 5

One roommate is saving to buy a house, so each month, he puts money aside in a special house savings account. The ratio of his monthly house savings to his rent is 1:3. If he pays $270 per month in rent, how much money does he put into his house savings account each month?

Correct Answer: A

Rationale: The correct answer is A: $90. Given the ratio of 1:3 for house savings to rent, and the rent of $270 per month, we can set up a proportion. Let x be the amount saved for the house. The ratio equation is: x/270 = 1/3. Cross-multiplying gives x = 270/3 = $90. Therefore, the roommate saves $90 each month. Choice B: $270 is incorrect because that is the amount of rent paid, not the amount saved for the house. Choice C: $730 is incorrect as it is not derived from the given ratio and rent amount. Choice D: $810 is incorrect as it is also not in line with the ratio and rent information provided.
