TEAS Test Math Questions

Correct Answer: B

Rationale: To find the median, we first arrange the data set in ascending order: 3, 5, 7, 9, 11. The median is the middle value when the data is ordered, which is 7 in this case. To confirm, count the numbers: there are 5 data points, making 7 the third value from both ends. Therefore, the median of the data set is 7. Choice A (3) is incorrect because it is the smallest value in the data set. Choice C (9) is incorrect because it is the second largest value in the data set. Choice D (5) is incorrect because it is the second smallest value in the data set.

Correct Answer: A

Rationale: To evaluate -3 x 5, we multiply -3 by 5 which gives us -15. The correct answer is A (-15) because when multiplying a negative and a positive number, the result is negative. Choice B (-2) is incorrect as it is the result of adding -3 and 5. Choice C (2) is incorrect as it is the result of multiplying -3 and -5. Choice D (15) is incorrect as it is the result of multiplying 3 and 5, not -3 and 5.

Correct Answer: D

Rationale: To determine the correct answer, we need to find the value of x in each proportion. For choice A, x = 4; for choice B, x = 8; for choice C, x = 6; and for choice D, x = 10. So, the correct answer is D because it yields a different value for x compared to the other choices. Choices A, B, and C all have x values that are multiples of 2, whereas choice D has a different x value. Therefore, choice D is the only proportion that yields a different number for the unknown compared to the others.

Correct Answer: A

Rationale: The perimeter of a square is calculated by adding up all four sides. Since all sides of a square are equal, the perimeter is 4 times the length of one side. In this case, the side length is 6 cm, so the perimeter would be 4*6 = 24 cm. Therefore, choice A (24 cm) is correct. Choices B, C, and D are incorrect because they do not correctly calculate the perimeter of a square with a side length of 6 cm. Choice B (12 cm) is half the correct answer, choice C (18 cm) is three-quarters of the correct answer, and choice D (36 cm) is double the correct answer.

Correct Answer: A

Rationale: To calculate how many times larger the first cell is compared to the second, we divide the diameter of the first cell by the diameter of the second cell: 0.1 / 0.05 = 2. Therefore, the correct answer is A: 2. Option B, C, and D are incorrect because they do not accurately represent the ratio between the two cell sizes based on the given diameters.
