Solution:
Hi there!
From the given conditions:
[tex]1→1 ⟹1 \times 1 = 1[/tex]
[tex]5→7⟹ 5 \times 7 = 35[/tex]
[tex]8→11 ⟹8 \times 11 = 88[/tex]
[tex]9→4 ⟹9 \times 4 = 36[/tex]
[tex]10 →2 ⟹10 \times 2 = 20[/tex]
Sum = 180, no. of customers = 25
[tex]average = \frac{sum}{no.ofcustomers} [/tex]
[tex] ⟹ \frac{180}{25} = 7.2[/tex]
Therefore, on average, the satisfaction rating of the landscape company was 7.2
