Question

Quizplus · Accepted Answer

To find out how many students had a score at or below 8, we need to add up the scores of all the students who took the quiz and then count the number of students who had a score at or below 8. Let's assume there were 100 students who took the quiz. If we add up all their scores, we get 1000 (100 students x 10 points each). To find out how many students had a score at or below 8, we need to find what percentage of 1000 is 8 or below. We can do this by dividing 8 by 1000 and then multiplying the result by 100. This gives us 0.008, which we can multiply by 100 to get 0.8%. Therefore, the percentage of students who had a score at or below 8 is approximately 0.8%. However, since none of the answer choices are exactly 0.8%, the closest one is 75%, which is the same as 0.75. Therefore, the best choice is A) 75%.
