D 1414

Answer 3

[AI-generated answer — Bot GPT 3.5]

Let's calculate the minimum number of points Xzavier could have earned on the test with a positive score:

Correct answers contribute +3 points each, while incorrect answers lose -4 points each and unanswered questions lose -1 point.

Xzavier answered 20 questions. The minimum possible score is obtained by assuming that all unanswered questions resulted in a loss of points. So, -1 point is lost for each of the remaining questions.

Now let's calculate the minimum score:
Total score = (20 questions answered correctly * 3 points each) + (10 questions unanswered * (-1))
Total score = 60 + (-10)
Total score = 50

Xzavier must have scored a positive total score to get a positive overall response. This means he needs at least 51 points to have a positive score.

Let's analyze the options:
A. 15 questions: (15*3) + (15*(-1)) = 45 - 15 = 30 (Not enough points)
B. 12 questions: (12*3) + (18*(-1)) = 36 - 18 = 18 (Not enough points)
C. 13 questions: (13*3) + (17*(-1)) = 39 - 17 = 22 (Not enough points)
D. 14 questions: (14*3) + (16*(-1)) = 42 - 16 = 26 (Not enough points)

Since none of these options result in a positive score, we have a slight issue with the question setup. The minimum number of questions answered correctly for a positive score needs to be reconsidered.

Let's recalculate to select the option that fits Xzavier's performance:

If Xzavier answered 20 questions, the total possible points are 20 * 3 = 60.

To have a positive score, Xzavier needs to earn more than the possible penalties for incorrect or unanswered questions (20 unanswered questions would lose 20 points). So, he needs to earn at least the same number of points as the possible penalties or more.

Let's check the provided options:
A. 15 questions: (15 * 3) + (15 * -1) = 45 + (-15) = 30
B. 12 questions: (12 * 3) + (18 * -1) = 36 + (-18) = 18
C. 13 questions: (13 * 3) + (17 * -1) = 39 + (-17) = 22
D. 14 questions: (14 * 3) + (16 * -1) = 42 + (-16) = 26

Xzavier needs a minimum of 20 points to have a positive score, so the correct answer among the options provided is:
C. 13 questions: (13 * 3) + (17 * -1) = 39 + (-17) = 22

Therefore, the minimum number of questions that Xzavier answered correctly to earn a positive score is 13.

Answer 6

The marketing department for a large sporting equipment store determined that 82% of the customers who purchase an item on sale also purchase at least one item not on sale. Based on this information, if 2,500 customers purchase an item on sale the day after Thanksgiving, how many of these customers will also purchase at least one item not on sale?

Responses
A 2,0052,005
B 250250
C 205205
D 2,050

Answer 7

[AI-generated answer — Bot GPT 3.5]

To find out how many of the 2,500 customers will also purchase items not on sale, we need to use the given percentage that 82% of customers who purchase an item on sale will also purchase at least one item not on sale.

First, we calculate the number of customers who will purchase an item not on sale:
82% of 2,500 = 0.82 * 2,500 = 2,050.

Therefore, the answer is:
D. 2,050 customers.

It appears the histogram data was not provided in the question. Without the data from the histogram, it is not possible to accurately determine whether each statement is true or false based on that data.

If you can provide the data or describe the histogram visually, I can assist in evaluating the statements.
