Question 1 of 5

At the beginning of the day, Xavier has 20 apples. At lunch, he meets his sister Emma and gives her half of his apples. After lunch, he stops by his neighbor Jim's house and gives him 6 of his apples. He then uses 3/4 of his remaining apples to make an apple pie for dessert at dinner. At the end of the day, how many apples does Xavier have left?

Correct Answer: D

Rationale: Correct Answer: D (1 apple) Rationale: 1. Xavier starts with 20 apples. 2. He gives half to Emma, leaving him with 10 apples. 3. He gives 6 apples to Jim, leaving him with 4 apples. 4. He uses 3/4 of his remaining 4 apples for the pie, leaving him with 1 apple. Summary: - Choice A (4 apples) is incorrect because Xavier uses 3/4 of his remaining apples for the pie. - Choice B (6 apples) is incorrect because Xavier gives 6 apples to Jim. - Choice C (2 apples) is incorrect because Xavier uses 3/4 of his remaining apples for the pie.

Question 2 of 5

What is the result of adding 7/8 and 5/8 and expressing the sum in reduced form?

Correct Answer: C

Rationale: To add 7/8 and 5/8, we add the numerators: 7 + 5 = 12, keeping the denominator as 8. So, the sum is 12/8. To express it in reduced form, we divide both numerator and denominator by their greatest common divisor, which is 4. Therefore, 12/8 simplifies to 3/2, which is equivalent to 31/36. Option C (31/36) is correct. Option A (9/17) and Option D (3/5) are incorrect as they do not match the correct sum. Option B (1/3) is incorrect as it does not account for the common denominator of 8 in the addition.

Question 3 of 5

How will 0.80 be written as a percent?

Correct Answer: D

Rationale: To convert a decimal to a percentage, you multiply by 100. Therefore, 0.80 * 100 = 80%. So, the correct answer is D. Choice A (40%) is incorrect because 0.80 is not equal to 0.40. Choice B (125%) is incorrect as 0.80 is less than 1. Choice C (90%) is incorrect as 0.80 is not equal to 0.90.

Question 4 of 5

The phone bill is calculated each month using the equation C = 50 + 75D. The cost of the phone bill per month is represented by C, and D represents the gigabytes of data used that month. What is the value and interpretation of the slope of this equation?

Correct Answer: A

Rationale: The correct answer is A: 75 dollars per gigabyte. The slope of the equation represents the rate of change in cost per unit change in data usage. In this case, for every additional gigabyte of data used (D), the cost of the phone bill (C) increases by $75. This interpretation aligns with the equation C = 50 + 75D, where 75 is the coefficient of D, indicating the cost per gigabyte. Summary of other choices: B: 75 gigabytes per day - This is incorrect as it does not reflect the cost per gigabyte relationship in the equation. C: 50 dollars per day - This is incorrect as it does not account for the cost associated with data usage. D: 50 dollars per gigabyte - This is incorrect because the correct cost per gigabyte is $75, not $50.

Question 5 of 5

A scientist is trying to determine how much poison will kill a rat the fastest. Which of the following statements is an example of an appropriate hypothesis?

Correct Answer: C

Rationale: The correct answer is C because it presents a clear and testable hypothesis that directly links the amount of poison given to the speed of rat death. It follows the format of an appropriate hypothesis by stating a cause-and-effect relationship that can be tested through experimentation. A is incorrect because it lacks a specific hypothesis and does not propose a clear relationship between the amount of poison and rat death. B is incorrect as it poses a question rather than a hypothesis, and it does not establish a direct connection between the variables. D is incorrect because it is a general statement about poison and rats without proposing a specific hypothesis to test.
