Answer:

2.33.

Step-by-step explanation:

First we find the mean by adding the values and dividing by 11 (the number of values).

mean = 62 / 11

= 5.636

Now, we list the absolute differences between each value and the mean:

9 - 5.636 = 3.364 the others are:

3.636, 3.636, 0.636, 2.636, 3.364, 0.364, 4.364, 1.636, 1.364, 0.636

Now the MAD is the sum of these values / 11.

MAD = 25.636/11

= 2.33..

Answer:

$23271.49

Step-by-step explanation:

The function $C(t) = C(1 + r)^{t}$ models the rise in the cost of a product that has a cost of C today, subject to an average yearly inflation rate of r for t years.

Now, if the average annual rate of inflation over the next 8 years is assumed to be 2.5% then we have to find the inflation-adjusted cost of a $19100 motorcycle after 8 years.

Therefore, the cost will be $C(8) = 19100(1 + \frac{2.5}{100} )^{8} = 23271.49$ dollars. (Answer)
