Practice Math TEAS TEST

Correct Answer: A

Rationale: The correct answer is A because in a proper fraction, the numerator (top number) is less than the denominator (bottom number). This indicates a fraction that is less than 1. In an improper fraction, the numerator is greater than the denominator, representing a fraction that is equal to or greater than 1. Choice B is incorrect because it reverses the definitions of proper and improper fractions. Choice C is incorrect because it suggests that a fraction is proper if the numerator is equal to the denominator, which is incorrect. Choice D is incorrect because it defines an improper fraction as having a numerator equal to the denominator, which is not the case.

Correct Answer: B

Rationale: The independent variable is the one that is manipulated or changed by the researcher in an experiment. In this scenario, the number of credit hours a student takes is the variable that is being controlled or changed to observe its effect on other variables such as tuition, access fees, and student loans. The amount of credit hours is not dependent on any other variable in this context, making it the independent variable. In contrast, the amount of tuition, access fees, and student loans are dependent on the number of credit hours taken by the student, making them dependent variables. Therefore, the correct answer is B: Number of credit hours. Choices A, C, and D are incorrect as they are all dependent variables that are influenced by the number of credit hours taken by the student.

Correct Answer: A

Rationale: The correct way to display the frequency for each day of the week when students get up after 8 a.m. is through a histogram. Histograms are used to display the distribution of continuous data into intervals or bins, making them ideal for showing frequency distributions. In this case, each day of the week can be represented along the x-axis, with the frequency of students getting up after 8 a.m. on the y-axis. By using a histogram, we can easily visualize and compare the frequency of waking up late on different days. Summary: - Choice A (Histogram) is correct as it effectively displays frequency distributions. - Choice B (Pie chart) is not suitable for showing frequency distributions of days of the week. - Choice C (Bar graph) could work but histograms are more specifically designed for this purpose. - Choice D (Scatter plot) is used to show relationships between two continuous variables, not frequency distributions.

Correct Answer: A

Rationale: The correct answer is A: 3x-12. To express 'Twelve less than thrice a number,' we first represent 'a number' as x. Then 'thrice a number' is 3x. Finally, 'Twelve less than thrice a number' translates to 3x-12. Other choices are incorrect because they do not accurately represent the given expression. Choice B (12-3x) reverses the order of operations, choice C (3-12x) incorrectly multiplies instead of subtracting, and choice D (12x-3) mistakenly subtracts the number from 12 instead of subtracting 12 from the number multiplied by 3.
