Math HESI A2 Practice Test

Correct Answer: C

Rationale: The correct answer is C: 16.60%. The probability of rolling a 5 on a fair six-sided die is 1/6, as there are 6 possible outcomes (1, 2, 3, 4, 5, 6) and only 1 favorable outcome (rolling a 5). To calculate the probability, you divide the number of favorable outcomes by the total number of outcomes, which is 1/6 = 0.1667 or 16.67%. Therefore, the closest choice is C: 16.60%. Explanation for other choices: A: 50% - Incorrect. This suggests that rolling a 5 is equally likely as not rolling a 5, which is not true for a fair six-sided die. B: 20% - Incorrect. This implies that rolling a 5 is 1 out of 5 possible outcomes, which is not the case for a standard six-sided die. D: 83

Correct Answer: C

Rationale: To convert quarts to ounces, you need to know that 1 quart equals 32 ounces. Therefore, 1.5 quarts would be 1.5 x 32 = 48 ounces. So, the correct answer is C (48 ounces). Choice A is incorrect as it incorrectly converts quarts to ounces. Choice B is half of the correct conversion. Choice D is double the correct conversion.

Correct Answer: D

Rationale: To find 50% of 120, you multiply 120 by 0.50 (which represents 50%). So, 120 x 0.50 = 60. Therefore, the correct answer is D. Choice A (50) is incorrect because it represents the percentage value, not the result of the calculation. Choice B (50) is a duplicate of Choice A. Choice C (70) is incorrect as it is not the result of finding 50% of 120.

Correct Answer: A

Rationale: To calculate the profit, we first find the total cost of cultivation: 240 acres * $188.99/acre = $45,357.60. Then, we find the total revenue from selling the yield: 240 acres * 60 bushels/acre * $5.67/bushel = $81,648. Finally, we subtract the cost from the revenue to get the profit: $81,648 - $45,357.60 = $36,290.40. Therefore, the correct answer is A. Choice B is incorrect because it miscalculates the profit by not subtracting the cost from the revenue. Choice C is incorrect as it overestimates the profit. Choice D is incorrect as it is not the accurate profit value based on the given information.

Correct Answer: A

Rationale: To convert 5/8 to a decimal, divide 5 by 8, which equals 0.625. The correct answer is A (0.625) because it is the result of dividing the numerator by the denominator. Choice B (0.5) is incorrect as 5/8 is not equal to 0.5. Choice C (0.4) and choice D (0.75) are also incorrect as they do not represent the equivalent decimal value of 5/8.
