I believe this is correct answer
Total amount of gas purchased by Ivy's father in the first week = 22.5 gallons
total amount of gas purchased by Ivy's father in the second week = 19.71 gallons
Let us assume the amount of gas purchased by Ivy's father in the third week = x
The total quantity of gas purchased in 3 weeks by Ivy's father = 61.75 gallons
Then
22.5 + 19.71 + x = 61.75
42.21 + x = 61.75
x = 61.75 - 42.21
= 19.54 gallons
So 19.54 gallons of gas was bought by Ivy's father in the third week
Mean means average.
To find the average, add the data then divide it by the amount of individual data you have.
(6.5 + 5 + 3 + 2 + 2 + 3.5 + 5)/2 = mean
27/2 = mean
13.5 = mean
13.5 miles is the mean distance that Jim jogged.
I dont understand wouldn't twice the number of 9 be 18 or 11?
