Answer 1

Given:

The total number of tamiliies is N = 30.

The objective is to find the mean number of gallons of milk consumed by 30 families.

Step-by-step explanation:

The total number of milk consumed consumed by 30 families can be calculated as,

`\begin{gathered} T=(8*3)+(9*2)+(13*5) \\ =24+18+65 \\ =107 \end{gathered}`

To find mean:

The mean number of gallons of milk can be calculated as,

`M=(T)/(N)`

On plugging the obtained values in the above equation,

`\begin{gathered} M=(107)/(30) \\ =3.56666\ldots\text{.} \\ =3.6 \end{gathered}`

Hence, the mean number of milk consumed by 30 families is 3.6 gallons.
