Question 1 of 5

A patient was taking 310 mg of an antidepressant daily. The doctor reduced the dosage by 1/5, and then reduced it again by 20 mg. What is the patient's final dosage?

Correct Answer: C

Rationale: To find the final dosage, we first reduce 310 mg by 1/5, which is 310 * (1 - 1/5) = 248 mg. Then, we further reduce it by 20 mg, resulting in 248 - 20 = 228 mg. Therefore, the patient's final dosage is 228 mg. Option A (20 mg) is incorrect because it only accounts for the second reduction. Option B (42 mg) is incorrect as it doesn't consider both reductions. Option D (248 mg) is incorrect as it doesn't factor in the second reduction.

Question 2 of 5

University Q has an extremely competitive nursing program. Historically, 3/4 of the students in each incoming class major in nursing, but only 1/5 of those who major in nursing complete the program. If this year's incoming class has 100 students, how many will complete the nursing program?

Correct Answer: C

Rationale: To find the number of students who will complete the nursing program, we first calculate the number of students majoring in nursing: 100 students * 3/4 = 75 nursing majors. Then, we determine how many of these nursing majors will complete the program: 75 nursing majors * 1/5 = 15 students. Therefore, the correct answer is C (15). Choice A (75) is incorrect because it represents the total number of nursing majors, not the number completing the program. Choice B (20) is incorrect as it does not consider the completion rate. Choice D (5) is incorrect as it is too low and does not account for the proportion of nursing majors who actually complete the program.

Question 3 of 5

A book has a width of 2.5 decimeters. What is the width of the book in centimeters?

Correct Answer: B

Rationale: To convert decimeters to centimeters, we use the conversion factor: 1 decimeter = 10 centimeters. Given the book's width is 2.5 decimeters, we multiply 2.5 by 10 to get the width in centimeters, which equals 25 centimeters. Therefore, choice B (25 centimeters) is the correct answer. Choices A, C, and D are incorrect because they do not correctly convert decimeters to centimeters based on the conversion factor. Choice A (0.25 centimeters) is a common mistake of misplacing the decimal point. Choice C (250 centimeters) is an error of incorrectly multiplying instead of using the conversion factor. Choice D (0.025 centimeters) is another mistake of misplacing the decimal point during conversion.

Question 4 of 5

Given the double bar graph shown below, which of the following statements is true?

Correct Answer: B

Rationale: The correct answer is B: Group A is positively skewed, while Group B is approximately normal. This is because in a positively skewed distribution, the tail of the graph extends to the right, indicating a higher frequency of lower values. In the double bar graph provided, Group A has a longer bar on the left side, suggesting a higher concentration of lower values, which is indicative of positive skewness. Group B, on the other hand, shows a more symmetrical distribution, with bars of similar length on both sides, implying an approximately normal distribution. Other choices are incorrect because: A: Group A is not negatively skewed, as it has a longer left tail. C: Group A is not approximately normal, as it shows characteristics of positive skewness. D: Group B is not positively skewed, as it does not have a longer right tail.

Question 5 of 5

Simplify the following expression: (3)(-4) + (3)(4) - 1

Correct Answer: A

Rationale: To simplify the expression, we first multiply: (3)(-4) = -12, (3)(4) = 12. Substitute these values back into the expression: -12 + 12 - 1 = -1. Therefore, the correct answer is A (-1). Choices B, C, and D are incorrect as they do not match the calculated result of -1.
