HESI A2 Practice Test Math - Nurselytic

Correct Answer: A

Rationale: In a class of 48 students, with 32 being female, the number of male students is 48 - 32 = 16.
To calculate the percentage of male students, divide the number of male students (16) by the total number of students (48) and then multiply by 100 to get the percentage: (16 / 48) * 100 = 33%.
Therefore, approximately 33% of the students in the class are male.

Choices B, C, and D are incorrect because they do not reflect the correct calculation based on the given information.

Correct Answer: A

Rationale: If 30% of a number is 18, you can find the full number by dividing 18 by 0.30 (the decimal equivalent of 30%). This calculation results in 60.
Therefore, the full number is 60.
Choice B (30) is the result if 30% of the number itself was calculated, not the full number.

Choices C (40) and D (45) are incorrect and do not align with the given information.

Correct Answer: A

Rationale:
To solve the expression, we follow the order of operations (PEMDAS). First, we divide 24 by 2 to get 12.
Then, we multiply 8 by 12, which equals 96. Finally, we subtract 96 from 2: 2 - 96 = -94.
Therefore, the correct answer is A, '-94'.

Choices B, C, and D are incorrect as they do not follow the correct order of operations or make errors during calculation.

Correct Answer: A

Rationale: The nurse worked a total of 40 hours (2 x 12 hours + 2 x 8 hours) during the week. Multiplying 40 hours by her hourly rate of $22 gives a total earning of $960 for the week.
Therefore, the correct answer is $960.
Choice B ($1,080) is incorrect because it miscalculates the earnings by adding extra hours.
Choice C ($990) is incorrect as it does not account for the correct number of hours worked.
Choice D ($880) is incorrect as it underestimates the total earnings by not considering all hours worked.
