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.

Correct Answer: A

Rationale: The correct answer is A: Equals. In math, "is" signifies equality between two expressions or values. It indicates that the quantities on both sides of the "=" sign are the same. For example, in the equation 2 + 3 = 5, the "is" represents that the sum of 2 and 3 equals 5. Explanation for other choices: B: Multiply - The symbol for multiplication is "*", not "is." C: Subtract - The symbol for subtraction is "-", not "is." D: Add - The symbol for addition is "+", not "is." Therefore, the correct interpretation of "is" in math is to denote equality, making choice A the correct answer.

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.

Correct Answer: B

Rationale: To find the total shifts for week 3, we add the shifts from each week. Cameron worked 5 shifts in week 1, 2 * 5 = 10 shifts in week 2, and added 4 more shifts in week 3. Thus, total shifts = 5 (week 1) + 10 (week 2) + 4 (week 3) = 19 shifts. Therefore, the correct answer is B: 14 shifts, as it correctly calculates the shifts for each week and provides the accurate total for week 3. Other choices are incorrect because they do not consider the shifts worked in week 2 or incorrectly calculate the total shifts for week 3.

Correct Answer: B

Rationale: To simplify the expression, we follow the order of operations (PEMDAS/BODMAS). First, we calculate the multiplication and division from left to right: 6 + 7 = 13, 13 - 4 = 9, 9 * 2 = 18. So, the correct answer is 18. Choice A is incorrect because it is the result of multiplying all the numbers together. Choice C is incorrect as it is the result of adding all the numbers together. Choice D is incorrect as it is the result of adding the first two numbers and then multiplying by the last two numbers.
