Step-by-step explanation:
I made a video explaining, I promise it’s not anything unrelated to the question. Here it is: https://youtu.be/jHVtTCYzmzI
A student gets an A in 3 credits (4, 4, 4)
B in 2 credits (3, 3)
C in a credit (2)
D in a credit (1)
Add each number together and divide by the amount of numbers there are:
(4 + 4 + 4 + 3 + 3 + 2 + 1)/7 = (21)/7 = 3
The mean is 3, or a B
hope this helps
