ATI TEAS Math Practice Test

Correct Answer: C

Rationale: To calculate the average, add up all the scores (81 + 92 + 87 + 89 + 94 = 443) and divide by the total number of scores (5). 443 ÷ 5 = 88.6, which rounds to 89. Therefore, the approximate average of Pernell's scores is 89. Summary: - A (81) is incorrect as it is the lowest score. - B (84) is incorrect as it is not the exact average of the scores. - D (91) is incorrect as it is higher than the calculated average.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. The total cost is directly proportional to the number of hours rented. 2. The cost per hour is $3.60, so multiplying the number of hours (h) by the cost per hour will give the total cost. 3. Therefore, the equation C = 3.60h correctly represents this relationship. Summary: B: Incorrect, as it incorrectly adds the number of hours to the cost per hour. C: Incorrect, as it unnecessarily adds a fixed cost of $10.80 to the total cost equation. D: Incorrect, as it incorrectly assumes a fixed cost per hour of $10.80.

Correct Answer: A

Rationale: To convert 56 kilograms to pounds, we use the conversion factor that 1 kilogram is approximately 2.2 pounds. So, 56 kg x 2.2 = 123.2 pounds. Since we are asked for the approximate weight in pounds, we round it to the nearest whole number, which is 123 pounds. Summary: - A (123 pounds) is correct because it is the accurate conversion of 56 kilograms to pounds. - B (110 pounds), C (156 pounds), and D (137 pounds) are incorrect as they do not correctly convert 56 kilograms to pounds using the conversion factor.

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: 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.
