Solve for the approximate measure of angle C. 38.66 36.87 53.13 51.34

Elis [28]

Answer:

m<C = 36.87degrees

Step-by-step explanation:

Solve for the approximate measure of angle C.

From the given diagram;

AC is the hypotenuse

BC is adjacent to <C

Cos m<C = adj/hyp

Cos m<C = BC/AC

Cos m<C = 20/25

Cos m<C = 0.8

m<C = arccos (0.8)

m<C = 36.87degrees

Answer:

$M.A.D=4$

Step-by-step explanation:

The given data set is :{63, 70, 68, 73, 58, 67}

The mean absolute deviation is the mean of how far all the entries in the data set are from the mean. Follow the procedure below;

find the mean of the data set
find the absolute value of the difference between the mean and each entry.
find the mean of these entries.

The mean is give by:

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

$\bar X=\frac{63+70+68+73+58+67}{6}$

$\bar X=\frac{399}{6}=66.5$

The mean absolute deviation is given by:

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

$M.A.D=\frac{|63-66.5|+|70-66.5|+|68-66.5|+|73-66.5|+|58-66.5|+|67-66.5|}{6}$

$M.A.D=\frac{3.5+3.5+1.5+6.5+8.5+0.5}{6}$

$M.A.D=\frac{24}{6}=4$
