Answer:
7.33
Step-by-step explanation:
In order to find the average of a set of given numbers, we simply need to add all the numbers given, then divide by the total number of values added.
In this case, we have 3 numbers, so we simply need to add all 3 numbers together, then divide by 3 to find the average:
[tex]\frac{6.18+8.21+7.59}{3} =\frac{21.98}{3}[/tex]≈ 7.33
(Note that although the answer should be 7.3266666... , we round to the number of decimal places that the question gives us, which is two decimal places. Additionally, rounding 7.326666... to 3 decimal places does not give us 7.326, so it is not the correct answer regardless)
