Correct Answer: A

Rationale: To find the percentage of patients hospitalized, we multiply the percentage who developed an infection by the percentage requiring hospitalization: 30% (infection rate) * 5% (hospitalization rate) = 1.5%. Therefore, the correct answer is A: 1.50%. Choices B, C, and D are incorrect because they do not accurately calculate the percentage of patients hospitalized based on the given data.

Correct Answer: C

Rationale: To find the circumference of a circle, we use the formula C = 2πr, where r is the radius. Given r = 3 inches, C = 2π(3) ≈ 18.85 inches. The closest estimate is C: 18 inches. Choice A is too small, B is slightly closer but still underestimated, and D is too large. Therefore, C is the best estimate based on the calculated circumference using the given radius.

Correct Answer: A

Rationale: To solve this question, we first need to find the ratio of girls to boys, which is 3:2. Then, we can set up a proportion to determine the number of girls. Since there are 3 girls for every 2 boys, the total ratio is 3+2=5 parts. To find the number of girls, we divide the total number of students by the total parts (650/5=130). Finally, we multiply the number of parts allocated to girls by the ratio of girls in the total parts (130*3=390). Therefore, there are 390 girls in Jim's school. Choice A (260) is incorrect as it does not consider the correct ratio. Choice B (130) is incorrect as it calculates the total parts instead of the number of girls directly. Choice C (65) is incorrect as it only considers one part of the ratio. Choice D (390) is incorrect as it miscalculates the number of boys, not

Correct Answer: B

Rationale: To maintain an overall average of at least 90, Dwayne needs to aim for the highest possible score. If he scores 98 on his next test, it will help balance any lower scores he may have received previously and ensure his average remains above 90. Choosing option B (98) is the best strategy as it allows for a margin of error while still meeting the target average. Options A, C, and D would not guarantee maintaining the required average as they are below 90.

Correct Answer: C

Rationale: To find the width, we first calculate the total length of the rectangle by multiplying the length by 2 (since there are 2 lengths in a rectangle). 12 cm x 2 = 24 cm. Subtracting this from the total perimeter of 36 cm gives us 36 cm - 24 cm = 12 cm. Since the width is divided into 2 sides, we divide 12 cm by 2 to get the width of 6 cm. Therefore, the correct answer is C: 6 cm. Choice A (3 cm) is incorrect because it does not account for the total perimeter. Choice B (12 cm) is incorrect as it represents the length, not the width. Choice D (8 cm) is incorrect as it does not align with the calculations based on the given information.
