none

Answer 1

3.215

Explanation:

Answer 2

Option B.

Explanation:

From the graph during first six months average rainfall was

1st month - 2.91 inches

2nd month - 2.60 inches

3rd month - 3.86 inches

4th month - 3.19 inches

5th month - 3.46 inches

6th month - 3.27 inches

Now we have to calculate the mean of these rainfalls during six months

Mean =
`\frac{\text{Total rainfall during six months}}{\text{Number of months}}`

=
`(2.91+2.60+3.86+3.19+3.46+3.27)/(6)`

=
`(19.29)/(6)`

= 3.215 inches

Therefore, mean of rainfall was 3.215 inches.

Option B is the correct option.
