Correct Answer: C

Rationale: To find the number of data analysis problems, first, determine the total ratio parts: 4 + 2 = 6. Then, calculate the number of parts for algebra problems: 2/6 * 18 = 6. Finally, find the number of data analysis problems: 4/6 * 18 = 12. Therefore, the correct answer is C (36). Option A (24) is incorrect as it miscalculates the ratio. Option B (28) and Option D (38) do not consider the given ratio and total number of algebra problems.

Correct Answer: C

Rationale: The perimeter of a hexagon is 6 times the length of one side. So, for a side length of 320 feet, the perimeter is 6 * 320 = 1920 feet. The cost of fencing is $1.75 per foot, so the total cost will be 1920 * $1.75 = $3360. Choice A is incorrect as it does not consider the correct perimeter calculation. Choice B is incorrect as it underestimates the total cost. Choice D is incorrect as it overestimates the total cost.

Correct Answer: C

Rationale: To find the total amount contributed, add the amounts given by each roommate: $12.03 + $11.96 + $12.06 = $36.05. Since we are estimating, we can round the total to $36. Therefore, the correct answer is C: $36. Choice A: $34 is incorrect because the total amount is more than $34. Choice B: $35 is incorrect because the total amount is more than $35. Choice D: $37 is incorrect because the total amount is less than $37.

Correct Answer: B

Rationale: To simplify the expression 13 - 3/22 - 11, we first calculate 3/22 which is 0.136. Then, we subtract 0.136 from 13, resulting in 12.864. Lastly, we subtract 11 from 12.864, giving us 1.864. Therefore, the correct answer is B: 7/22. Choices A, C, and D are incorrect as they do not match the simplified expression value of 1.864.

Correct Answer: B

Rationale: The correct answer is B: median. The median is the middle value when the data is arranged in numerical order. In this case, the outlier of 11 houses would significantly impact the mean, making it less accurate. The mode is not relevant for continuous data like the number of houses sold. The range only gives the difference between the maximum and minimum values, which does not provide a good measure of central tendency. Thus, the median is the best choice as it is not influenced by outliers and provides a more accurate representation of the typical number of houses sold per year.
