Practice Math TEAS TEST Questions
Question 1 of 5
What is the median of the data set below: 5, -3, 10, -2, 0?
Correct Answer: B
Rationale: To find the median, first, sort the data set in ascending order: -3, -2, 0, 5, 10. The middle value is the median, which is 0 in this case. This is the correct answer (B). The other choices are incorrect because: A: 10 is the highest value, not the middle value. C: 5 is not the middle value when the data set is arranged in ascending order. D: 2 is not present in the data set, making it an invalid choice.
Question 2 of 5
What is any number raised to the power of 1?
Correct Answer: A
Rationale: The correct answer is A: Itself. Any number raised to the power of 1 remains the same number. This is because any number to the power of 1 is equivalent to multiplying that number by 1, which does not change the value of the number. Therefore, when a number is raised to the power of 1, the result is the number itself. Summary of incorrect choices: B: One - Raising any number to the power of 1 does not always result in 1, it results in the original number itself. C: Zero - Raising any non-zero number to the power of 1 does not result in 0. D: The number multiplied by 2 - Raising a number to the power of 1 does not double the number, it remains the same.
Question 3 of 5
How do you find the factors of a number?
Correct Answer: B
Rationale: The correct answer is B: Find all pairs of numbers that multiply to give the number. To find factors, we need to identify pairs of numbers that, when multiplied together, result in the original number. This method ensures that we consider all possible combinations of factors. Dividing the number by all possible numbers (A) is not efficient and may lead to overlooking certain factors. Listing all the multiples of the number (C) is incorrect as it focuses on multiples rather than factors. Adding the digits of the number together (D) is unrelated to finding factors.
Question 4 of 5
Which of the following is the independent variable in the equation below? f(t)=4t+9
Correct Answer: C
Rationale: The independent variable is the variable that is manipulated or changed in an equation. In the equation f(t)=4t+9, 't' is the independent variable because it represents the input value that we can freely choose or vary. We can substitute different values for 't' to see how it affects the output 'f(t)'. On the other hand, 'f' is the dependent variable as it depends on the value of 't'. The constant term '9' and the coefficient '4' are not variables, so they cannot be independent variables. Therefore, choice C (t) is the correct answer. Choices A, B, and D are incorrect because they do not represent the independent variable in the given equation.
Question 5 of 5
As the number of credit hours a student takes in a semester increases, the amount of tuition, the amount of access fees, and the number of student loans available also increase. Which of the following is the independent variable?
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.
