Latishastarted her history class with two scores on tests, 72% and 89% confirmed that the mean of these two scores is 80.5% show your work
(72 + 89) / 2 = 80.5
To find the mean of two scores, you need to add the scores together and divide the sum by the number of scores.
Let's denote the first score as x and the second score as y.
The given information states that Latisha's first score is 72% (x = 72) and her second score is 89% (y = 89).
Now, we can calculate the mean by summing the two scores and dividing by 2 (since we have only two scores).
Mean = (x + y) / 2 = (72 + 89) / 2 = 161 / 2 = 80.5
Therefore, the mean of Latisha's two scores is 80.5%.
