What is the mean absolute deviation of the data set? {12, 10, 10, 8, 6, 7, 7, 12}
Simora [160]

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 length of a rectangle is 2 times it’s width if the perimeter of the rectangle is 36 inches find it’s length and width
Tamiku [17]

P = Perimeter            

L = Length          

W = Width

Perimeter of rectangle = L + L + W + W        

or P = 2L + 2W

You know:

P = 36 inches

L = 2W          [length is(=) 2 times it's width]

W = ?

P = 2L + 2W    

Substitute/plug in what you know, plug in 2W for L since L = 2W

36 = 2(2W) + 2W         Simplify

36 = 4W + 2W

36 = 6W        Divide 6 on both sides

6 = W              Now that you know the width, you can find the length:

L = 2W

L = 2(6)

L = 12

L = 12 in

W = 6 in

PROOF

P = 2(12) + 2(6)

P = 24 + 12

P = 36
