Correct Answer: A

Rationale: The correct answer is A: Eritrea. To determine the largest increase in healthcare spending per capita from 2013 to 2015, we need to calculate the difference between the spending in 2015 and 2013 for each country. By comparing the dollar amount increase for each country, it is evident that Eritrea experienced the largest increase. This is because the dollar amount increase for Eritrea is greater than that of the other countries listed. Sudan, Tanzania, and Kenya had smaller increases in dollars spent per capita during the same period. Therefore, A is the correct answer.

Correct Answer: A

Rationale: The correct answer is A: 2W + 2(W + 3). To find the perimeter of a rectangle, you add up all its sides. Given that the length is 3 units greater than the width, the length is represented as W + 3. So, the expression for the perimeter is 2W (for the width) + 2(W + 3) (for the length). This simplifies to 2W + 2W + 6, which further simplifies to 4W + 6, representing the correct perimeter expression. Summary: B: W + W + 3 is incorrect as it only adds the width twice and does not account for the length. C: W(W + 3) is incorrect as it represents the area of the rectangle, not the perimeter. D: 2W + 2(3W) is incorrect as it incorrectly combines the width and length terms in the expression.

Correct Answer: A

Rationale: The correct answer is A because to find the least common multiple (LCM) of two numbers, you need to list all the multiples of each number and then identify the smallest common multiple. This method ensures that you consider all possible common multiples and select the smallest one. Explanation for other choices: B: Listing factors and finding the largest common factor would result in the greatest common divisor, not the least common multiple. C: Dividing the largest number by the smallest does not give the LCM; it may give a different value altogether. D: Multiplying the two numbers together gives the product of the numbers, not the LCM.

Correct Answer: B

Rationale: The correct answer is B: 1 meter. This is the best estimate for the average width of a doorway because standard doorways typically range from 0.8 to 0.9 meters wide, and rounding up to 1 meter provides a reasonable estimate. Choice A (0.5 meters) is too small for a standard doorway. Choice C (10 meters) is too large and unrealistic for a doorway. Choice D (3 meters) is wider than the typical doorway width, making it an inaccurate estimate. Therefore, B is the most appropriate estimate based on common door sizes.

Correct Answer: C

Rationale: The data set has two distinct peaks at values 2 and 8, making it bimodal. This is evident as there are two modes in the data set. The frequencies of 2 and 8 are higher compared to the other values, creating the bimodal distribution. Choices A, B, and D are incorrect. A uniform distribution would have equal frequencies for all values, which is not the case here. Right-skewed distribution would have a long tail on the right side, which is also not observed. Left-skewed distribution would have a long tail on the left side, which is not the case here.
