Question

Find the mean for each set of data.
245, 65, 123, 100, 22, 43, 36, 177, 21

Answer 1

The mean of a data is the average of the numbers. It can be calculated by summing up the numbers in a set of data and dividing it by the number of terms.

`mean=\frac{\texttt{sum of data}}{\texttt{number of terms}}`

Let's calculate the sum of the data:

`245+65+123+100+22+43+36+177+21`

`=832`

Now, let's divide the sum by the number of terms(9 terms):

`832/9`

`\boxed{92.44}` (mean)

Answer 2

Answer: 92.444

Explanation:

245 + 65 + 123 + 100 + 22 + 43 + 36 + 177 + 21 = 832

832 / 9 = 92.44444444444
