Practice Math TEAS TEST Questions
Question 1 of 5
What is a prime number?
Correct Answer: A
Rationale: The correct answer is A: 'A number divisible by only 1 and itself.' A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. This definition aligns with choice A.
Choice B is incorrect because not all prime numbers are divisible by 2 and 3.
Choice C is incorrect as prime numbers are not divisible by any number other than 1 and themselves.
Choice D is incorrect because a prime number has exactly two factors, 1 and itself, not three factors.
Question 2 of 5
Which of the following options correctly orders the numbers below from least to greatest? 235.971, 145.884, -271.906, -193.823
Correct Answer: A
Rationale:
To correctly order the numbers from least to greatest, we start with the smallest number, which is -271.906, followed by -193.823, 145.884, and finally 235.971.
Therefore, the correct order is -271.906, -193.823, 145.884, 235.971.
Choice A is correct.
Choice B is incorrect as it incorrectly places 235.971 before -193.823.
Choice C is incorrect as it starts with the largest number, 145.884.
Choice D is incorrect as it starts with -193.823, which is not the smallest number in the list.
Question 3 of 5
What is the mathematical expression for 'Twelve less than thrice a number'?
Correct Answer: A
Rationale: The phrase 'thrice a number' translates to 3x, and 'twelve less than' means subtracting 12 from it.
Therefore, the correct expression is 3x-12.
Choice B, '12-3x', represents '12 less than a number thrice,' which is the opposite of the given phrase.
Choice C, '3-12x', does not correctly interpret the phrase provided.
Choice D, '12x-3', represents 'a number thrice less than twelve,' which is not the same as the original phrase.
Question 4 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 correct answer is the number of credit hours. In this scenario, the number of credit hours is the independent variable because it is the factor that is intentionally changed or manipulated. The amount of tuition, access fees, and student loans are dependent variables as they are influenced by the number of credit hours a student takes. The number of credit hours drives the changes in the other factors, making it the independent variable.
Question 5 of 5
A new physician saw 841 clients during the first year of practice and 1072 clients during the second year of practice. Which of the following represents the approximate percentage increase in client volume?
Correct Answer: B
Rationale:
To calculate the percentage increase, subtract the initial value from the final value, then divide by the initial value and multiply by 100. In this case, the calculation is ((1072 - 841) / 841) x 100 ≈ 27%.
Therefore, the correct answer is B.
Choice A (22%) is incorrect as it does not match the calculated percentage increase.
Choice C (127%) is incorrect as it represents an absolute increase, not a percentage increase.
Choice D (78%) is incorrect as it is not close to the calculated percentage increase of 27%.
