Question 1 of 5
In Mrs. McConnell's classroom, there are 5 students with hazel eyes and 2 students with green eyes out of a total of 30 students. What percentage of the students have either hazel or green eyes?
Correct Answer: A
Rationale: To find the percentage of students with hazel or green eyes, add the number of students with hazel and green eyes (5+2=7). Then, divide this sum by the total number of students (7/30). Finally, multiply the result by 100 to convert it to a percentage (7/30 * 100 = 23%). Therefore, the correct answer is A (0.23). Choice B (0.3) is incorrect as it is not the accurate percentage of students with hazel or green eyes. Choice C (0.47) and choice D (0.77) are also incorrect as they do not represent the correct calculation of the percentage based on the given information.
Question 2 of 5
If Stella's current weight is 56 kilograms, what is her approximate weight in pounds?
Correct Answer: A
Rationale: To convert kilograms to pounds, we use the conversion factor 1 kg = 2.20462 lbs. So, to find Stella's weight in pounds, we multiply her weight in kilograms (56) by the conversion factor: 56 kg * 2.20462 lbs/kg ≈ 123.46 lbs. Therefore, Stella's approximate weight in pounds is 123 pounds. Choice B (110 pounds) is incorrect as it underestimates the conversion. Choice C (156 pounds) and D (137 pounds) overestimate the conversion.
Question 3 of 5
How many quarts are in a gallon?
Correct Answer: D
Rationale: The correct answer is D: 4 quarts. There are 4 quarts in a gallon. This is because a gallon is a unit of volume equal to 128 fluid ounces, and each quart is equal to 32 fluid ounces. Therefore, to find out how many quarts are in a gallon, you divide the total number of fluid ounces in a gallon by the number of fluid ounces in a quart (128 ÷ 32 = 4). Choice A (1 quart) is incorrect because a quart is smaller than a gallon. Choice B (2 quarts) is incorrect as it is half of the correct amount. Choice C (3 quarts) is also incorrect as it is three-quarters of the correct amount. The correct answer is D (4 quarts) because it accurately represents the conversion of fluid ounces from gallons to quarts.
Question 4 of 5
How many quarts are in 1 liter?
Correct Answer: B
Rationale: To convert liters to quarts, we use the conversion factor 1 liter = 1.06 quarts. Therefore, 1 liter is equal to 1.06 quarts. The correct answer is B. Choice A is incorrect as it states 1 quart is equal to 1 liter. Choice C is incorrect as it states 2 quarts are in 1 liter. Choice D is incorrect as it states 0.5 quarts are in 1 liter.
Question 5 of 5
Given a double bar graph, which statement is true about the distributions of Group A and Group B?
Correct Answer: B
Rationale: The correct answer is B: Group A is positively skewed, Group B is normal. In a double bar graph, skewness can be identified based on the distribution of bars. 1. Positive skewness means the tail of the distribution extends to the right, indicating a higher frequency of lower values. 2. Looking at Group A, if the bars are concentrated on the left side with a few bars extending to the right, it suggests positive skewness. 3. Group B being normal implies a symmetrical distribution with no skewness. Therefore, B is correct as it correctly describes the skewness of Group A and Group B based on the given information. Summary: A: Incorrect - Group A is positively skewed, not negatively skewed. C: Incorrect - Group B is normal, not neutral. D: Incorrect - Group A is positively skewed, not normal.
