Question

brody took 7 science tests. his scores were: 71 points, 72 points, 74 points, 73 points, 73 points, 74 points, 74 points. what was brodys mean test score? round your answer to the nearest whole number. points

Explanation:

Step1: Sum all test scores

To find the mean, we first sum all the scores. The scores are 71, 72, 74, 73, 73, 74, 74.
So, \(71 + 72 + 74 + 73 + 73 + 74 + 74\)
Let's calculate step by step:
\(71 + 72 = 143\)
\(143 + 74 = 217\)
\(217 + 73 = 290\)
\(290 + 73 = 363\)
\(363 + 74 = 437\)
\(437 + 74 = 511\)

Step2: Divide by number of tests

There are 7 tests. So the mean is the sum divided by 7.
Mean \(= \frac{511}{7}\)
\(\frac{511}{7} = 73\) (since 7*73 = 511)

Answer:

73
