B is the midpoint of A . If AB = x+5 and BC =2x-11, find the measure of AB

nignag [31]

If B is the midpoint of AC, then AB = BC.

We have AB = x + 5 and BC = 2x - 11.

Therefore we have the equation:

x + 5 = 2x - 11 subtract 5 from both sides

x = 2x - 16 subtract 2x from both sides

-x = -16 change the signs

x = 16

Put the value of x to the expression x + 5:

AB = 16 + 5 = 21

<h3>Answer: AB = 21</h3>

QUESTION 3 of 10: Stock returns vary from year to year. The more variance a stock displays the greater the potential risk. These

Dahasolnce [82]

Answer:

The variance of these investment returns is 74

Step-by-step explanation:

Given:

Series = 10, 30, 15, 5, 20

To Find:

variance of a series = ?

Solution:

The variance of the series = $Var\left(X\right)=\sum _{i=1}^n\frac{\left(x_i-\bar{x}\right)^2}{n}$

$\bar{x} = \frac{10+30 +5+15 + 20}{5}$

$\bar{x} = \frac{80}{5}$

$\bar{x} =16$

Now $(x_i -\bar{x})^2 =$ $(10 -16)^2 + (30 -16)^2 + (5 -16)^2 +(15 -16)^2 +(20 -16)^2$

= $(-6)^2 + (14)^2 + (-11)^2 + (-1)^2+ (-4)^2$

= 36 + 196 +121 + 1+ 16

= 370

Now

$Var\left(X\right)=\frac{370}{5}$ = 74
