ATI TEAS Math Practice Test

Correct Answer: B

Rationale: The correct answer is B: median. The median is the middle value when the data is arranged in numerical order. In this case, the outlier of 11 houses would significantly impact the mean, making it less accurate. The mode is not relevant for continuous data like the number of houses sold. The range only gives the difference between the maximum and minimum values, which does not provide a good measure of central tendency. Thus, the median is the best choice as it is not influenced by outliers and provides a more accurate representation of the typical number of houses sold per year.

Correct Answer: B

Rationale: To simplify the expression 3(1/6) - 1(5/6), we first multiply the whole number by the fraction: 3 * 1/6 = 3/6. Then, we subtract 1 * 5/6 = 5/6. Simplifying 3/6 - 5/6 gives us -2/6, which reduces to -1/3 or 1 (1/3). Therefore, the correct answer is B: 1 (1/3). Choice A: 2 (1/3) is incorrect as the result is negative. Choice C: 2 (1/9) is incorrect as it is not the simplified form. Choice D: 5/6 is incorrect as it is one of the terms in the expression, not the final result.

Correct Answer: A

Correct Answer: C

Rationale: To earn more than 96 points, Mathew needs to answer at least 97 points out of 120 (40 questions * 3 points each). This means he can only get a maximum of 23 questions wrong (120 - 97 = 23). So, Mathew can answer up to 7 questions incorrectly (23/3 = 7.67, rounded down to 7) and still qualify for varsity sports. Therefore, the correct answer is C: 0 ≤ x < 8, as Mathew can answer 0 to 7 questions incorrectly and still meet the eligibility requirement. Choices A, B, and D are incorrect because they do not accurately reflect the maximum number of questions Mathew can answer incorrectly based on the total points needed for eligibility.

Correct Answer: B

Rationale: To find the percentage of total staff certified and available to work, we first calculate the percentage of staff available: 100% - 35% = 65%. Then, we find the percentage of the remaining staff who are certified: 65% x 20% = 13%. Therefore, the correct answer is B (13%). Choice A (7%) is too low, as it only considers the percentage of certified staff. Choice C (65%) is incorrect as it represents the percentage of total staff available, not certified. Choice D (80%) is incorrect as it does not take into account the percentage of staff who are both certified and available.
