Answer:

D. 14.32

Step-by-step explanation:

The formula for standard deviation is:

$SD = \sqrt{\frac{\sum | x-\mu|^2}{N}}$

The mean μ is 33.

The (x minus μ) squared are 361, 49, 49, 361 respectively.

So that the SD = $\sqrt{\frac{820}{4}} \approx 14.31782...$

Answer:

Step-by-step explanation:

2)

x + 14 $\frac{13}{25}$ = -0.87

x + $\frac{363}{25}$ = - $\frac{87}{100}$

x + $\frac{1452}{100}$ = - $\frac{87}{100}$

x = - $\frac{87}{100}$ - $\frac{1452}{100}$

x = - $\frac{1539}{100}$

3)

x -8 $\frac{5}{6}$ = 1.5

x - $\frac{53}{6}$ = $\frac{9}{6}$

x = $\frac{9}{6}$ + $\frac{53}{6}$

x = $\frac{62}{6}$

x = $\frac{31}{3}$

4)

x - $\frac{7}{12}$ = - 7 $\frac{7}{16}$

x - $\frac{28}{48}$ = - $\frac{119}{16}$

x = - $\frac{357}{48}$ + $\frac{28}{48}$

x = - $\frac{329}{48}$

5)

$\frac{8}{9}$ - x = 6 $\frac{1}{15}$

$\frac{8}{9}$ = $\frac{91}{15}$ + x

$\frac{40}{45}$ - $\frac{273}{45}$ = x

- $\frac{233}{45}$ = x

x = - $\frac{233}{45}$

6)

-33.754 - x = 28.05

-33.754 - 28.05 = x

- 61.804 = x

x = - 61.804
