TEAS Practice Math Test

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: 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.

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: A

Rationale: The mode is the value that appears most frequently in a set of numbers. In this distribution, the number 1 appears the most times (5 times), making it the mode. Choice A is correct. Choices B, C, and D are incorrect because they do not represent the value that appears most frequently in the distribution.

Correct Answer: B

Rationale: The best estimate of the total number of pounds of potatoes on the farmer's trailer can be calculated by finding the average weight per bag and then multiplying it by the total number of bags. Since each bag contains between 23 to 27 pounds, we can estimate the average weight per bag to be around 25 pounds. With 150 bags, the total weight would be approximately 150 bags * 25 pounds per bag = 3,750 pounds. Therefore, the best estimate is 3,700 pounds (Choice B). Choice A (3,000 pounds) is too low as it assumes the lowest possible weight per bag consistently. Choice C (4,100 pounds) is too high as it assumes the highest possible weight per bag consistently. Choice D (5,000 pounds) is also too high and overestimates the total weight based on the given information.
