Not entirely sure but it may be 35 mpg.
The answer for this question is 0.22
9.5 because 9.5-7 is 2.5. 2.5 times 4/5 is 10/5 which is equivalent to 2. 4/5(2.5-7)=2
The answer is A because the median is the middle number (4) in an ascending or descending list of numbers and the mean is 3 because if you take the four numbers above 0 you get the total then divide the total by how many numbers there are you get your mean and 15 divided by 5 is 3. Hopefully this helped if not I can explain a little more if you need it!!
