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: A

Rationale: The correct answer is A: $600. The first step is to calculate the amount saved after paying rent and utilities. Since she uses 2/5 for rent and utilities, she saves 3/5 of her monthly contribution. Then, she saves half of this amount for incidental expenditures, which means she spends the other half on medical supplies. Therefore, she spends 1/4 of her monthly contribution on medical supplies. If we let her monthly contribution be x, then 1/4 of x equals $600. Therefore, the correct answer is $600. Choices B, C, and D are incorrect because they do not align with the calculations based on the given information.

Correct Answer: A

Rationale: The correct answer is A (35). To find the number of students who chose blue, multiply the total number of students by the percentage that chose blue: 100 x 0.35 = 35. This calculation gives us the number of students who said blue is their favorite color. The other choices are incorrect because they do not correctly calculate the number of students who chose blue based on the given percentage. Choice B (25), C (20), and D (10) do not accurately represent 35% of the total number of students. Therefore, choice A is the correct answer based on the calculation method provided.

Correct Answer: D

Rationale: To find the total bonus amount, we need to work backwards. Since Chan has $600 remaining after paying taxes, donating, and paying off debt, this $600 represents 15% of his original bonus (100% - 30% - 30% - 25% = 15%). Therefore, $600 is equivalent to 15% of the bonus. To find the total bonus amount, we divide $600 by 15% (or 0.15), which equals $4,000. Thus, the correct answer is D: $4,000. Choice A ($3,000) is incorrect because it does not account for the remaining $600. Choice B ($3,200) and choice C ($3,600) are also incorrect as they do not reflect the correct percentage left after all deductions, which is 15%.
