TEAS Practice Math Test

Correct Answer: A

Rationale: The correct answer is A because it shows a direct proportion between the initial deposit and the monthly deposits. The relationship is proportional as the amount deposited per month remains constant ($125). This indicates a consistent ratio between the initial deposit and subsequent deposits. B is incorrect as it involves a fixed hourly rate and a bonus, not a proportional relationship. C is incorrect as it involves fixed monthly cost and variable cost per minute, not a proportional relationship. D is incorrect as it states a constant rate of speed, not a proportional relationship based on changing variables.

Correct Answer: C

Rationale: To determine the order from least to greatest, convert all fractions to decimal equivalents. -2 3/4 = -2.75 -2 7/8 = -2.875 -1/5 = -0.2 1/8 = 0.125 2/5 = 0.4 Now arrange them in ascending order: -2.875, -2.75, -0.2, 0.125, 0.4 Therefore, the correct order from least to greatest is -2 7/8, -2 3/4, -1/5, 1/8, 2/5 (Option C). Other choices are incorrect as they do not follow the correct order of the numbers when arranged from least to greatest.

Correct Answer: D

Rationale: The correct answer is D: The mode is equal to the range. In this case, the mode is the value that appears most frequently in the data set. The mode for the given data set is 29, as it appears twice. The range is the difference between the highest and lowest values in the data set. In this case, the range is 46 - 17 = 29. Therefore, the mode (29) is equal to the range (29), making option D the correct choice. A: The mean is less than the median - This is incorrect as the mean is calculated by adding all values and dividing by the total number of values, while the median is the middle value when the data is arranged in order. In this case, the mean is greater than the median. B: The mode is greater than the median - This is incorrect as the mode (29) is equal to the median (also 29). C: The mode is less than the mean,

Correct Answer: D

Rationale: To solve for x, we add 7 to both sides of the equation: 2x - 7 + 7 = 3 + 7. This simplifies to 2x = 10. Then, we divide both sides by 2 to solve for x: 2x/2 = 10/2, which gives x = 5. Therefore, the correct answer is D. Choice A is incorrect because 4 does not satisfy the equation. Choice B is incorrect as x = 3 does not make the equation true. Choice C is incorrect as x = -2 does not satisfy the equation either.

Correct Answer: C

Rationale: To find the number of students who passed the exam, we first need to determine the total number of students who took the exam. Since half of the nursing students took the exam, the number of students who took the exam is 200/2 = 100. Then, three-fifths of those who took the exam passed, which is 3/5 * 100 = 60 students. Therefore, the correct answer is C (60). Choice A (120) is incorrect because it represents the total number of nursing students, not the number of students who passed the exam. Choice B (100) is incorrect because it represents the total number of students who took the exam, not the number who passed. Choice D (50) is incorrect because it does not consider the percentage of students who passed the exam.
