Answer:

c = 8.06

Step-by-step explanation:

Use the Pythagorean theorem.

a^2 + b^2 = c^2

c^2 = a^2 + b^2

c^2 = 4^2 + 7^2

c^2 = 16 + 49

c^2 = 65

c = sqrt(65)

c = 8.06

Solution: The correct option is d. 8.75

<u>Explanation:</u>

The formula for variance is:

$Variance =\frac{\sum(x-\bar{x})^{2}}{n}$

First we need to find the mean $\bar{x}$ of the given data:

$\bar{x}=\frac{2+4+6+0+1+10+9+0+6+3+6+8+5+4+6+2}{16}=\frac{72}{16} =4.5$

Now let's find $\sum(x-\bar{x})^{2}$ , please have a look at the attached picture:

$\therefore Variance = \frac{140}{16}=8.75$
