Question

the professor decides to assign a grade of a to the students with the top 8% of the grades, and a grade of a to the next best 12%. what is the minimum percentage a student needs to earn a grade of a? (a) 77 (b) 78 (c) 79 (d) 80 (e) 81

Answer 1

The minimum percentage a student needs to earn a grade of A is 79%. Option c

Step-by-step explanation:

To find the minimum percentage a student needs to earn a grade of A, we need to determine the cutoff percentage for the top 8% of grades. Since the total number of students is not given, we can assume a large number for simplicity.

Let's say there are 100 students. The top 8% of grades would be given to 8 students, and the next best 12% would be given to the next 12 students. To find the minimum percentage, we need to find the percentage that falls in between the 8th and 9th student's grade.

So, the minimum percentage a student needs to earn a grade of A is 79% (option c).
