Answer 2

The number of innings Brantley pitched is 7.

Explanation:

We are given that the table shows the number of innings pitched by each of the Greenbury Goblins' starting pitchers during the Rockbottom Tournament below;

Pitcher Number of innings pitched

Calvin 11

Thom 12

Shawn 7

Kris 3

Brantley x

Let the number of innings Brantley pitched be 'x'.

The mean of the following data set is given by the following formula;

Mean =
`\frac{\text{Sum of all data values}}{\text{Total number of observations}}`

`8 = (11+12+7+3+x)/(5)`

`8* 5 =33+x`

`40 = 33+x`

x = 40 - 33 = 7

Hence, the number of innings Brantley pitched is 7.
