Final answer:

To find the average (mean) of the given test scores, add up all the numbers and then divide the sum by the total number of scores. The average test score is 76.

Step-by-step explanation:

To find the average (mean) of the given test scores, you add up all the numbers and then divide the sum by the total number of scores. In this case, the test scores are 83, 92, 47, 78, and 80.

Adding up these scores, we get 83 + 92 + 47 + 78 + 80 = 380.

Dividing the sum by the total number of scores, which is 5 in this case, we get 380 ÷ 5 = 76.

Therefore, the average test score is 76.

Answer:

add them all together then divide among them.

Add 83 + 92 + 47 + 78 + 80 = 380

then divide by the amount of test which is 5 because we have 5 test scores

divide 380 ÷ 5 = 76

The average percentage for all is 76%

Hope this helps :)
