Correct Answer: A

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: C

Rationale: The correct answer is C, the least common multiple of both denominators. To find the least common denominator of two fractions, you need to determine the smallest number that both denominators can evenly divide into. This is achieved by finding the least common multiple (LCM) of the denominators. The LCM is the smallest number that is a multiple of both denominators, ensuring that when you convert the fractions to have the same denominator, they will be in their simplest form. In contrast, option A is not correct as it refers to finding the least common multiple, not denominator. Option B is incorrect as it does not consider the need for the fractions to have the same denominator. Option D is also incorrect as it refers to the greatest common factor, which is not relevant when finding the least common denominator.

Correct Answer: A

Rationale: The correct answer is A: This is a linear association with a positive correlation. This scatterplot shows a clear pattern where the data points form a straight line that slopes upward from left to right, indicating a positive correlation. Positive correlation means that as one variable increases, the other variable also tends to increase. In this case, the data points are clustered around the line, showing a strong linear relationship. Choices B, C, and D are incorrect because the scatterplot does not exhibit a negative correlation, nonlinear association, or no association. The linear pattern with a positive slope in the scatterplot supports the selection of choice A as the best description of the data.

Correct Answer: B

Rationale: The correct answer is B: 1,000 mm. This is because there are 1,000 millimeters in a meter. The metric system is based on units of 10, so to convert meters to millimeters, you multiply by 1,000 (10 x 10 x 10). Therefore, 1 meter equals 1,000 millimeters. Choice A (100 mm) is incorrect as it represents centimeters, not millimeters. Choice C (10,000 mm) and Choice D (100,000 mm) are incorrect because they are multiples of 1,000 and would be equivalent to 10 meters and 100 meters respectively, not millimeters.

Correct Answer: A

Rationale: The correct answer is A because a histogram represents continuous data with no gaps between bars, while a bar graph displays discrete data with gaps between bars. Option B is incorrect because both graphs can display frequency. Option C is incorrect as both can be used for comparison. Option D is incorrect as both can include labels.
