Answer 1

After removing the two lowest scores from Payton's homework scores, the average of the remaining scores is calculated to be 86.75, which is then rounded to the nearest tenth to give an overall homework score of 86.8.

Step-by-step explanation:

To determine Payton's overall homework score in Mr. Daley's class, we have to first remove the two lowest homework scores and then calculate the average of the remaining scores. Payton's scores are as follows: 85, 56, 67, 90, 95, 86, 0, 83, 100, and 88. The two lowest scores are 0 and 56, which we will omit.

Now, we have the following scores to consider: 85, 67, 90, 95, 86, 83, 100, and 88.

The next step is to calculate the average of these scores.

The sum of the remaining scores is 85 + 67 + 90 + 95 + 86 + 83 + 100 + 88 = 694.

To find the average, we divide this sum by the number of scores, which is 8 in this case.

The average score is 694 / 8 = 86.75.

Finally, we round the average score to the nearest tenth of a point, which results in an overall homework score of 86.8.
