Answer:

The MAD of  {12, 10, 10, 8, 6, 7, 7, 12} is 2.

Step-by-step explanation:

<u><em>Step 1 : Add all the values Up:</em></u>

<u><em /></u>12+10+10+8+6+7+7+12=72

<u><em>Step 2 : Divide them by the number of items or numbers:</em></u>

<u><em></em></u>\frac{12+10+10+8+6+7+7+12}{8}=9<u><em></em></u>

<u><em></em></u>

<u><em>Step 3: Find the absolute deviations:</em></u>

<u><em></em></u>12-9=3\\10-9=1\\10-9=1\\9-8=1\\9-6=3\\9-7=2\\9-7=2\\12-9=3\\<u><em></em></u>

<u><em>Step 4: Add all the absolute deviations:</em></u>

3+1+1+1+3+2+2+3=16

<u><em>Step 5: Find the mean:</em></u>

\frac{3+1+1+1+3+2+2+3}{8}=2

The value of a collector’s item is expected to increase exponentially each year. The item is purchased for $500. After 2 years,

Y = 500(1 + r)^x; where r is the rate and x is the number of years.
500(1 + r)^2 = 551.25
(1 + r)^2 = 551.25/500 = 1.1025
1 + r = sqrt(1.1025) = 1.05

Therefore, the equation that represents y, the value of the item after x years is
y = 500(1.05)^x
