Isaac keeps track of the miles per gallon his car gets per week. He has accumulated the following data:
(1, 24), (2, 24.48), (3, 24.97), (4, 25.47)
What is the common difference or ratio?
The common difference is 0.48.
The common difference is 0.50.
The common ratio is 0.98.
The common ratio is 1.02.
i think it is a!
OpenStudy (shamil98):
difference means subtraction.
24.48-24 = 0.48
24.97-24.48 = 0.49
So you can cancel out option A .
undeadknight26 (undeadknight26):
I know it is not c or d...so its b?
undeadknight26 (undeadknight26):
c and d have multiplication right?
OpenStudy (shamil98):
Ratio is division.
it isn't b.

24 x 1.02 = 24.48
24.48 x 1.02 = 24.97
24.97 x 1.02 = 25.47
OpenStudy (shamil98):
why would you do 24/.98
OpenStudy (shamil98):

24.48/24 = 1.02
