1. Gerald received the following test scores in math class: 76, 86, 89, 81, and 99. What was Gerald’s average test score, rounded to the nearest point?
Add the five scores and divide by 5 to find the average.
To find Gerald's average test score, you need to sum up all the test scores and divide the sum by the total number of tests.
Here's how you can do it:
Step 1: Add up all the test scores
76 + 86 + 89 + 81 + 99 = 431
Step 2: Divide the sum by the total number of tests
Since there are 5 test scores, divide the sum (431) by 5:
431 ÷ 5 = 86.2
Step 3: Round the result to the nearest whole number
Since the question asks for the answer to be rounded, round the decimal part to the nearest point:
86.2 rounds to 86
Therefore, Gerald's average test score, rounded to the nearest point, is 86.
