Correct Answer: B

Rationale: To find the median, first, sort the data set in ascending order: -3, -2, 0, 5, 10. The middle value is the median, which is 0 in this case. This is the correct answer (B). The other choices are incorrect because: A: 10 is the highest value, not the middle value. C: 5 is not the middle value when the data set is arranged in ascending order. D: 2 is not present in the data set, making it an invalid choice.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Given equation: D = 2R 2. To find the relationship between D and R, we see that D is equal to 2 times R. 3. Thus, D is twice as much as R, making choice A the correct answer. 4. Other choices are incorrect: - B: R is twice as much as D (incorrect as the equation shows D is twice R). - C: R is two times D (incorrect as the equation states D is two times R). - D: D is two more than R (incorrect as D is actually two times R).

Correct Answer: A

Rationale: The correct answer is A: One. Any number raised to the power of zero equals one. This is because the rule for exponents states that any number raised to the power of zero is equal to one, regardless of the base number. This rule is derived from the properties of exponents and is a fundamental concept in mathematics. Choices B, C, and D are incorrect because raising a number to the power of zero does not result in the number itself, zero, or two. The key to remember is that any number raised to the power of zero is always equal to one, making choice A the correct answer.

Correct Answer: D

Rationale: To find the correct answer, we first calculate how much of the burger was left after one friend ate a quarter (3/4 left). Then, the other two friends divide this among themselves equally, so each receives half of the remaining portion (3/4 * 1/2 = 3/8). Therefore, each of the other two friends received 3/8 of the burger, which is represented by choice D (8-Mar). Choices A, B, and C are incorrect because they do not accurately reflect the correct calculation of dividing the remaining portion equally between the two friends.

Correct Answer: A

Rationale: The correct answer is A: 3x-12. To express 'Twelve less than thrice a number,' we first represent 'a number' as x. Then 'thrice a number' is 3x. Finally, 'Twelve less than thrice a number' translates to 3x-12. Other choices are incorrect because they do not accurately represent the given expression. Choice B (12-3x) reverses the order of operations, choice C (3-12x) incorrectly multiplies instead of subtracting, and choice D (12x-3) mistakenly subtracts the number from 12 instead of subtracting 12 from the number multiplied by 3.
