Question 1 of 5

A die is rolled. What is the probability of getting a 5?

Correct Answer: C

Rationale: The correct answer is C: 16.60%. The probability of rolling a 5 on a fair six-sided die is 1/6, as there are 6 possible outcomes (1, 2, 3, 4, 5, 6) and only 1 favorable outcome (rolling a 5). To calculate the probability, you divide the number of favorable outcomes by the total number of outcomes, which is 1/6 = 0.1667 or 16.67%. Therefore, the closest choice is C: 16.60%. Explanation for other choices: A: 50% - Incorrect. This suggests that rolling a 5 is equally likely as not rolling a 5, which is not true for a fair six-sided die. B: 20% - Incorrect. This implies that rolling a 5 is 1 out of 5 possible outcomes, which is not the case for a standard six-sided die. D: 83

Question 2 of 5

A pizza has a diameter of 40cm. What is its perimeter (circumference)?

Correct Answer: C

Rationale: To find the perimeter (circumference) of a circle, we use the formula C = πd, where d is the diameter. Given the diameter of the pizza is 40cm, we substitute this into the formula: C = π * 40 = 125.6cm (Choice C). This is the correct answer as it accurately calculates the circumference. Choices A, B, and D are incorrect because they do not provide the correct calculation based on the given diameter. Choice A (62.8cm) seems to be using the formula for the circumference of a circle with radius, not diameter. Choices B and D are simply incorrect calculations.

Question 3 of 5

Add: 3 1/8 + 1 1/4.

Correct Answer: A

Rationale: To add 3 1/8 and 1 1/4, first convert both to improper fractions: 3 1/8 = 25/8 and 1 1/4 = 5/4. Then, add the fractions: 25/8 + 5/4 = 50/8 + 10/8 = 60/8 = 7 1/2. Convert 7 1/2 back to a mixed number: 7 1/2 = 6 2/8 = 6 1/4 = 4 3/8, which is the correct answer (A). Choice B (4 1/2) is incorrect as it doesn't match the calculated sum. Choice C (4 3/4) is incorrect as it is not the simplified form of the sum. Choice D (5 1/4) is incorrect as it is higher than the calculated sum.

Question 4 of 5

Convert 3/4 to a decimal.

Correct Answer: A

Rationale: To convert 3/4 to a decimal, divide 3 by 4. 3 ÷ 4 = 0.75, so the correct answer is A. Choice B (0.5) is incorrect because that's the decimal form of 1/2. Choice C (0.65) and D (0.85) are incorrect as they do not represent the fraction 3/4 accurately.

Question 5 of 5

How many meters are in 2 kilometers?

Correct Answer: C

Rationale: To convert kilometers to meters, we need to multiply the number of kilometers by 1000 since there are 1000 meters in 1 kilometer. So, 2 kilometers x 1000 meters/kilometer = 2000 meters. Therefore, the correct answer is C: 2000 meters. Choice A (100 meters) is incorrect as it does not account for the conversion factor of 1000 meters in 1 kilometer. Choice B (200 meters) is incorrect for the same reason. Choice D (3000 meters) is incorrect as it goes beyond the actual conversion calculation.
