Answer:
77.2%
Step-by-step explanation:
The average formula is:
Let's first find the sum of all the numbers (remember sum means to add):
(2)(85) + (4)(78) + (3)(66) + 92 = ?
170 + 312 + 198 + 92 = 772
There are marks for 10 students so that is what goes at the bottom (10 students, 10 test scores)
Plug both things into the equation:
Therefore, the average mark on the test was 77.2%
