ATI TEAS Math Practice Test

Correct Answer: B

Rationale: To simplify the expression 13 - 3/22 - 11, we first calculate 3/22 which is 0.136. Then, we subtract 0.136 from 13, resulting in 12.864. Lastly, we subtract 11 from 12.864, giving us 1.864. Therefore, the correct answer is B: 7/22. Choices A, C, and D are incorrect as they do not match the simplified expression value of 1.864.

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: D

Rationale: The correct answer is D because in this study, the dependent variable is what is being measured or affected (average hours worked per week), and the independent variable is what is being manipulated or controlled (hospital staff types). The average hours worked per week can vary based on the different types of hospital staff, so the staff types are the independent variable. The incorrect choices fail to correctly distinguish between the dependent and independent variables, mixing up the roles of nurses, physicians, and hospital staff with the average hours worked per week.

Correct Answer: C

Rationale: To calculate the distance traveled by the train, we use the formula Distance = Speed x Time. Given the speed of 60 mph and time of 2 hours, Distance = 60 mph x 2 hours = 120 miles. Therefore, the correct answer is C: 120 miles. Choice A is incorrect because it only represents the speed of the train, not the total distance. Choice B and D are incorrect as they do not consider both speed and time to calculate the distance correctly.

Correct Answer: D

Rationale: The correct answer is D (6.97 hours). To calculate the total time taken, first find the time for the first segment: 305 miles / 65 mph = 4.69 hours. Then add the 15-minute stop in hours: 15 minutes / 60 = 0.25 hours. Next, find the time for the second segment: 162 miles / 80 mph = 2.025 hours. Add up these times: 4.69 hours + 0.25 hours + 2.025 hours = 6.965 hours, which rounds to 6.97 hours. Choice A is incorrect as it does not account for the distance covered and the stop. Choices B and C are incorrect as they do not consider the time for the second segment.
