Question 1 of 5

In a research study, a researcher collects data on the number of hours spent studying and the grades students received. Which of the following is the dependent variable?

Correct Answer: B

Rationale: The correct answer is B: The grades students received. The dependent variable is the outcome that is being measured or observed in response to changes in the independent variable. In this research study, the grades students received are dependent on the number of hours spent studying, which is the independent variable. The grades received will vary based on the amount of time spent studying. Choices A, C, and D are incorrect because they are not the outcome or response variable being measured in relation to the independent variable of hours spent studying. A is the independent variable, C is not a variable in this context, and D is not directly related to the outcome being measured.

Question 2 of 5

The cost of renting a bicycle is $3.60 per hour. Which equation shows the best relationship between the total cost (C) and the number of hours (h) rented?

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. The total cost is directly proportional to the number of hours rented. 2. The cost per hour is $3.60, so multiplying the number of hours (h) by the cost per hour will give the total cost. 3. Therefore, the equation C = 3.60h correctly represents this relationship. Summary: B: Incorrect, as it incorrectly adds the number of hours to the cost per hour. C: Incorrect, as it unnecessarily adds a fixed cost of $10.80 to the total cost equation. D: Incorrect, as it incorrectly assumes a fixed cost per hour of $10.80.

Question 3 of 5

Complete the following equation: 2 + (2)(2) - 2 � 2 = ?

Correct Answer: A

Rationale: Failed to generate a rationale after 5 retries.

Question 4 of 5

Pernell received the following scores on five exams: 81, 92, 87, 89, and 94. What is the approximate average of these scores?

Correct Answer: C

Rationale: To calculate the average, add up all the scores (81 + 92 + 87 + 89 + 94 = 443) and divide by the total number of scores (5). 443 ÷ 5 = 88.6, which rounds to 89. Therefore, the approximate average of Pernell's scores is 89. Summary: - A (81) is incorrect as it is the lowest score. - B (84) is incorrect as it is not the exact average of the scores. - D (91) is incorrect as it is higher than the calculated average.

Question 5 of 5

If Stella's current weight is 56 kilograms, which of the following is her approximate weight in pounds? (Note: 1 kilogram is approximately equal to 2.2 pounds.)

Correct Answer: A

Rationale: To convert 56 kilograms to pounds, we use the conversion factor that 1 kilogram is approximately 2.2 pounds. So, 56 kg x 2.2 = 123.2 pounds. Since we are asked for the approximate weight in pounds, we round it to the nearest whole number, which is 123 pounds. Summary: - A (123 pounds) is correct because it is the accurate conversion of 56 kilograms to pounds. - B (110 pounds), C (156 pounds), and D (137 pounds) are incorrect as they do not correctly convert 56 kilograms to pounds using the conversion factor.
