Well the first thing that came to my mind was to do rise/run and doing that I got 6/5 which I added together to get 11 but since that's obviously not correct I assumed it was a little under so the answer I got was 7.8
Really hope this helps!
Answer:
C. 
Step-by-step explanation:
Iterative geometric sequence:

Recursive geometric sequence:

The equations are very similar and you only really need to rearrange it. The factor (2/3) and the first term (9) are given, so you can write the iterative equation:

And so the answer is C.
Answer:
For this case a parameter represent the population data and for this case the parameter would be the true mean
who represent the amount of gasoline they used in the previous week

And the sample mean is an unbiased estimator of the true mean.
Step-by-step explanation:
For this case a parameter represent the population data and for this case the parameter would be the true mean
who represent the amount of gasoline they used in the previous week
And in order to estimate the parameter of interest we use a survey of n =3800 and the sample mean who represent an statistic is given by:

And we got:

And the sample mean is an unbiased estimator of the true mean.
