How would the information about grade and frequency change if there were twice as many of each grade?

Grade Frequency
A 2
B 8
C 11
D 2
F 1
I think that the grades would double if there was twice as many. Thanks.

You are wrong. You didn't answer the frequency part.

What is the difference between 2/15 and 4/30?

The difference between 2/15 and 4/30 is .133333333. Where did you come up with 2/15 and 4/30? I'm confused now.

How would I go about answering the frequency part?

How did you get the difference between 2/15 and 4/30 as .1333 repeating? 4/30 = 2/15

Consider that if there were twice as many of each grade, the total would be twice as great, but so would the number of grades. So the average would be the same.

Is this answer correct? Just double each number. The "frequency" establishes a percentage breakdown ( unless something else changes ) would stay the same no matter how many grades there are. With every grade doubling, the percentage breakdown stays the same.

To determine how the information about grade and frequency would change if there were twice as many of each grade, we need to multiply the frequency of each grade by 2.

Let's go through each grade:

Grade A: Frequency is currently 2. If there were twice as many Grade A, multiply 2 by 2, which gives us 4.

Grade B: Frequency is currently 8. If there were twice as many Grade B, multiply 8 by 2, which gives us 16.

Grade C: Frequency is currently 11. If there were twice as many Grade C, multiply 11 by 2, which gives us 22.

Grade D: Frequency is currently 2. If there were twice as many Grade D, multiply 2 by 2, which gives us 4.

Grade F: Frequency is currently 1. If there were twice as many Grade F, multiply 1 by 2, which gives us 2.

So, the updated information about grade and frequency would be:

Grade Frequency
A 4
B 16
C 22
D 4
F 2
