TEAS Practice Math Test Questions
Question 1 of 5
What was the mean time for the women who ran the 200m event at the 2008 Olympic Games (times in seconds: 22.33, 22.50, 22.50, 22.61, 22.71, 22.72, 22.83, 23.22)?
Correct Answer: C
Rationale: The mean time for the women who ran the 200m event at the 2008 Olympic Games can be calculated by summing all the times and dividing by the total number of times. Sum of times = 22.33 + 22.50 + 22.50 + 22.61 + 22.71 + 22.72 + 22.83 + 23.22 = 182.42 Total number of times = 8 Mean time = 182.42 / 8 = 22.8025 ≈ 22.68 sec (Choice C) Therefore, the correct answer is C (22.68 sec) as it is the closest to the calculated mean time. Incorrect choices: A: 22.50 sec - This is not the mean of the given times. B: 22.66 sec - Not the mean. D: 22.77 sec - Not the mean.
Question 2 of 5
The number of vacuum cleaners sold by a company per month during Year 1 is listed below: 18, 42, 29, 40, 24, 17, 29, 44, 19, 33, 46, 39. Which of the following is true?
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,
Question 3 of 5
A rectangular solid box has a square base with a side length of 5 feet and a height of h feet. If the volume of the box is 200 cubic feet, which of the following equations can be used to find h?
Correct Answer: C
Rationale: Failed to generate a rationale after 5 retries.
Question 4 of 5
Solve for x: 2x - 7 = 3
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.
Question 5 of 5
Which of the following is listed in order from least to greatest?
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.
