3.10 A student's final grades in mathematics, physics, English and hygiene are, respectively, 82, 86, 90, and 70. If the respective credits received for these courses are 3, 5, 3, and 1, determine an appropriate average grade. Hence the appropriate average grade is 85.

Answer 2

Answer:

An appropriate average grade is $85$.

Step-by-step explanation:

Given data:

Final grades in Mathematics = 82, Credits received = 3

Final grades in Physics = 86, Credits received = 5

Final grades in English = 90, Credits received = 3

Final grades in Hygiene = 70, Credits received = 1

Formula:

$Average=\frac{Sum\ of\ the\ terms}{Number\ of\ terms}$

Put the given terms in above formula, we get

Average = $\frac{(82\times 3+86\times 5+90\times 3+70\times 1)}{3+5+3+1}$

Average = $\frac{(246+430+270+70)}{12}$

Average = $\frac{1016}{12}$

Average = $84.66\approx 85$

Appropriate average grade = $85$
