The scale factor is  0.25, not 4 in this case.  You can determine this by looking at the comparison of the triangles.  The first triangle is 4.4 and the second one is 1.1, so the scale factor is determined by looking at what is happening to the first one to result in the second.

0.25 is 1/4.  The second hypotenuse is 1/4 the hypotenuse of the first one.

Find the MAD of this set of data.
barxatty [35]

Answer:

2.8

Step-by-step explanation:

The given data set is;

6, 12, 10, 9, 8, 6, 2, 4, 8, 15

The mean of this set is;

\bar X=\frac{\sum x}{n}

\bar X=\frac{6+12+10+9+8+6+2+4+8+15}{10}

\bar X=\frac{80}{10}=8

The mean absolute deviation is given by

M.A.D=\frac{\sum |x-\bar X|}{n}

M.A.D=\frac{|6-8|+|12-8|+|10-8|+|9-8|+|8-8|+|6-8|+|2-8|+|4-8|+|8-8|+|15-8|}{10}

M.A.D=\frac{2+4+2+1+0+2+6+4+0+7}{10}

M.A.D=\frac{28}{10}

M.A.D=2.8

FG = 47 * 0.9
FG = 42.3
