Question

Number 4, please help

Answer 1

Hi there!

From the given conditions:

`1→1 ⟹1 * 1 = 1`

`5→7⟹ 5 * 7 = 35`

`8→11 ⟹8 * 11 = 88`

`9→4 ⟹9 * 4 = 36`

`10 →2 ⟹10 * 2 = 20`

Sum = 180, no. of customers = 25

`average = (sum)/(no.ofcustomers)`

`⟹ (180)/(25) = 7.2`

Therefore, on average, the satisfaction rating of the landscape company was 7.2
