How to use the results of part (b) and appropriate computation formulas to compute the sample variances s2 and sample standard d

anygoal [31]

$s^2=\displaystyle\sum\frac{(x-\bar x)^2}{n-1}=\frac1{n-1}\sum(x^2-2x\bar x+{\bar x}^2)=\frac{\displaystyle\sum x^2-2\bar x\sum x+{\bar x}^2}{n-1}$

where $\bar x=22$ is the mean. Since

$\sum x^2=2568$
$\sum x=110$

you have variance

$s^2=\dfrac{2568-2(22)(110)+22^2}{5-1}=37$

and so the standard deiviation is

$s=\sqrt{37}\approx6.083$

What is the measure of each interior angle of a regular decagon (10 sides)?

bixtya [17]

6)a

if we put n as the number of sides in a regular polygon, the formula to find the measure of each angle is
$\frac{(n - 2) \times 180}{n}$
so the answer will be
$\frac{(10 - 2) \times 180 }{10} = \frac{1440}{10} = 144$
they each measures 144 degrees

good luck
