ATI TEAS Math Practice Test

Correct Answer: D

Rationale: To solve the equation 2x + 4 = x - 6, we need to isolate x. Subtract x from both sides to get x + 4 = -6. Then, subtract 4 from both sides to get x = -10. The correct answer is D, x = -10. Choice A is incorrect because x is not -12. Choice B is incorrect as x is not 10. Choice C is incorrect as x is not -16.

Correct Answer: C

Rationale: The independent variable is the variable that is manipulated or controlled by the researcher. In this case, the number of nurses in various specialties is the variable that is being studied and is not dependent on any other variable. Therefore, the correct answer is C - Nurse specialties. Choices A, B, and D are incorrect as they are either specific specialties or the dependent variable (number of nurses).

Correct Answer: C

Rationale: To find the number of students who will complete the nursing program, we first calculate the number of students majoring in nursing: 100 students * 3/4 = 75 nursing majors. Then, we determine how many of these nursing majors will complete the program: 75 nursing majors * 1/5 = 15 students. Therefore, the correct answer is C (15). Choice A (75) is incorrect because it represents the total number of nursing majors, not the number completing the program. Choice B (20) is incorrect as it does not consider the completion rate. Choice D (5) is incorrect as it is too low and does not account for the proportion of nursing majors who actually complete the program.

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: C

Rationale: The perimeter of a hexagon is 6 times the length of one side. So, for a side length of 320 feet, the perimeter is 6 * 320 = 1920 feet. The cost of fencing is $1.75 per foot, so the total cost will be 1920 * $1.75 = $3360. Choice A is incorrect as it does not consider the correct perimeter calculation. Choice B is incorrect as it underestimates the total cost. Choice D is incorrect as it overestimates the total cost.
