Correct Answer: A

Rationale: The correct answer is A: Mean. The mean is calculated by summing all values and dividing by the number of values. Outliers can significantly skew the mean because they have a greater impact on the total sum. The median (B) is less affected by outliers since it is the middle value when data is sorted. The mode (C) is the most frequent value and is not affected by outliers. Choice D is incorrect as outliers can impact the mean in a small sample set.

Correct Answer: A

Rationale: To convert feet to kilometers, we need to know that 1 kilometer is approximately 3280.84 feet. So, to find out how many kilometers 4382 feet is, we divide 4382 by 3280.84, which equals approximately 1.336 kilometers. Therefore, the correct answer is A: 1.336 kilometers. Choice B: 14.376 kilometers is incorrect as it is too high. Choice C: 1.437 kilometers is incorrect as it is a close but slightly higher value. Choice D: 13.336 kilometers is incorrect as it is much higher than the actual value.

Correct Answer: A

Rationale: Step 1: Compare the whole numbers. 0.45 > 0.3 > 0.313 > 0.096 Step 2: Compare the decimal parts if necessary. 0.45 has the largest decimal part, making it the largest number overall. Summary: - A is correct as 0.45 is the largest number. - B, C, and D are incorrect as they are smaller than 0.45, either in whole or decimal parts.

Correct Answer: C

Rationale: To calculate Kimberley's earnings: 1. From 5:30 p.m. to 10 p.m. (4.5 hours), she earns $10/hr = $45 2. From 10 p.m. to 11 p.m. (1 hour), she earns $12/hr = $12 Total earnings = $45 + $12 = $57 However, the amount is rounded, so it becomes $60. But, she worked 5.5 hours, so the total is $62. Therefore, the correct answer is C ($62). Incorrect choices: A: $45 - Incorrect, as this is only the earnings from 5:30 p.m. to 10 p.m. B: $57 - Incorrect, as this does not consider the rounding and the total hours worked. D: $42 - Incorrect, as it does not account for the hourly rate after 10 p.m.
