The table below shows the number of shoppers at Jacob's store over a period of five months:
Olin [163]

We are given table

Month :         1     2        3         4         5

Shoppers:   50  250   1250   6250  3250

so, we have

first term =50

a_1=50

Second term =250

a_2=250

Third term =1250

a_3=1250

a_4=6250

a_5=31250

now, we can find ratios

\frac{a_2}{a_1} =\frac{a_3}{a_2}=\frac{a_4}{a_3}=\frac{a_5}{a_4}=5

we can see that all ratios are same and 5

so, this is exponential

so, option-D..........Answer

The proportion of buses traveling more than 900 miles would be 0.0485; multiply this by the total number of buses and you will have your answer.

We find the z-score associated with 900 miles:

z = (X - μ)/σ = (900-830.11)/42.19 = 1.66

Using a z-table (http://www.z-table.com) we see that the area under the curve to the left of this, less than this, is 0.9515.  This means that the area under the curve to the right of this, greater than this, would be 1-0.9515 = 0.0485.
