HESI A2 Math Practice Exam Questions
Question 1 of 5
After taking several practice tests, Brian improved the results of his GRE test by 30%. Given that the first time he took the test Brian answered 150 questions correctly, how many questions did he answer correctly on the second test?
Correct Answer: D
Rationale: To find out how many questions Brian answered correctly on the second test, we first calculate the 30% increase from his initial score of 150 questions. 30% of 150 is 45, so his new score is 150 + 45 = 195 questions. Therefore, the correct answer is D (195). Choice A (105) is incorrect because it is less than the initial score of 150. Choice B (120) is incorrect because it does not account for the 30% increase. Choice C (180) is incorrect as it is the result of adding 30% to the initial score, not the final score after the increase.
Question 2 of 5
A table shows the average blood pressure readings for different age groups. How do you determine the highest average systolic pressure?
Correct Answer: A
Rationale: The correct answer is A because to determine the highest average systolic pressure, you need to find the largest number in the "systolic pressure" column. This is because the average is calculated based on all the values in the column, and the highest number will have the most significant impact on the average. By finding the largest number, you ensure that the highest average systolic pressure is accurately identified. Option B is incorrect because comparing the means of each age group does not specifically pinpoint the highest average systolic pressure. Option C is incorrect as it calculates the overall average rather than focusing on the highest value. Option D is incorrect as subtracting the lowest from the highest does not give the highest average systolic pressure.
Question 3 of 5
If his distribution cost is $10, what will be his profit?
Correct Answer: B
Rationale: The correct answer is B: $19.60. To calculate profit, we subtract the distribution cost from the total revenue. If the distribution cost is $10, and profit is the remainder, then profit = total revenue - distribution cost. Let's denote total revenue as TR. Therefore, profit = TR - $10. Since the distribution cost is $10, the profit will be TR - $10. To find TR, we add the distribution cost to the profit: TR = profit + $10. If we substitute $10 for the distribution cost and $19.60 for profit, we get TR = $19.60 + $10 = $29.60. This means that the correct answer for the profit will be $19.60. Summary: A: $10.40 - Incorrect. This choice is lower than the distribution cost, so it cannot be the profit. C: $14.90 - Incorrect. This choice is also lower than the distribution cost, ruling
Question 4 of 5
Convert the fraction 7/8 into a decimal and percent.
Correct Answer: A
Rationale: To convert 7/8 into a decimal, you simply divide the numerator (7) by the denominator (8), which equals 0.875. To convert to a percent, you multiply the decimal by 100, resulting in 87.5%. Choice A is correct as it correctly represents the decimal and percent equivalents of 7/8. Choices B, C, and D are incorrect because they provide inaccurate decimal and percent conversions that do not match the correct calculations for 7/8.
Question 5 of 5
After taking several practice tests, Brian improved the results of his GRE test by 30%. Given that the first time he took the test Brian answered 150 questions correctly, how many questions did he answer correctly on the second test?
Correct Answer: D
Rationale: To find out how many questions Brian answered correctly on the second test, we first calculate the 30% increase from his initial score of 150 questions. 30% of 150 is 45, so his new score is 150 + 45 = 195 questions. Therefore, the correct answer is D (195). Choice A (105) is incorrect because it is less than the initial score of 150. Choice B (120) is incorrect because it does not account for the 30% increase. Choice C (180) is incorrect as it is the result of adding 30% to the initial score, not the final score after the increase.
