Scrat [10]

Answer:

80.88

Step-by-step explanation:

The mean is the average of the numbers. To calculate that, just add up all the numbers, and then divide by how many numbers there are. In other words it is the sum divided by the count.

95 + 45 + 37 .....

divided by 24 (the total number of numbers)

1,941 / 24  =  80.875

80.8<u>7</u>5 rounded to the nearest hundredth =  80.88

        *

(hundredths place)

Rounding rule: If the digit to the right of the place you are rounding to is 5 or more, then round up to the next digit.
