Correct Answer: B

Rationale: To round 2678 to the nearest thousandth, we look at the digit in the thousandth place, which is 6. Since the next digit is 7, we round 6 up to 7. The thousandth place is used to decide whether to round up or down in this case. Choices A, C, and D are incorrect as they refer to other place values that are not relevant when rounding to the nearest thousandth.

Correct Answer: C

Rationale: To reach $300, Bernard needs to work for $300 / $80 = 3.75 days. Since he can only work full days, he needs to work for 4 days to make at least $300. Thus, the correct answer is C. Option A (2 days), B (3 days), and D (5 days) are incorrect as they do not meet the minimum requirement of $300.

Correct Answer: C

Rationale: The sequence is an arithmetic progression with a common difference of 1. To find the sixth number, we add 1 successively to each number. Starting from 5, we add 1 five times to get the sixth number, which is 5 + 5 = 10. Therefore, the correct answer is B. Choice A is incorrect because it is the fourth number in the sequence. Choice C is incorrect as it is the seventh number. Choice D is incorrect as it is the eighth number in the sequence.

Correct Answer: B

Rationale: To find the overall median, we first arrange the scores in ascending order: 78, 83, 92, 97. The median is the middle value, which is 92 in this case. Therefore, the correct answer is B. Choice A is incorrect as it is not a score in the list. Choice C is incorrect as it is the median of the list, not the overall median. Choice D is incorrect as it is the average of all scores, not the median.

Correct Answer: D

Rationale: To find the number of nights Sarah needs to read 140 pages, we first calculate her rate: 21 pages / 4 nights = 5.25 pages/night. Then, we divide 140 pages by her rate: 140 pages / 5.25 pages/night ≈ 26.67 nights. Since she can't read a fraction of a night, she would need 27 nights to read 140 pages. A: Incorrect. 6 nights is too short based on the rate calculation. B: Incorrect. 26 nights is close, but rounding up is necessary. C: Incorrect. 8 nights is too short based on the rate calculation.
