AB is parallel to BE because it is an equilateral triangle.

BE is parallel to EC because it has 2 of the same angles to the same sides are equal.

Hope that helps, it's a tad hard to explain

What is the volume of a sphere that has a 12m diameter?

lesya [120]

Volume of Sphere = (4/3)*(pi)*(r^3)

r = (D/2) = 6 m

  =<span>(4/3)*(pi)*((6^3)

  = 904.7786.. m^3
I hope this helps.</span>

6 - 8a + 5a - 35

Fittoniya [83]

Ok, so after you do -8a+5a, you also have to do 6 -35, getting the equation
-29-3a

g If the economy improves, a certain stock stock will have a return of 23.4 percent. If the economy declines, the stock will hav

dusya [7]

Answer:

$E(X) = 23.4* 0.67 -11.9*0.33= 11.759 \%$

Now we can find the second central moment with this formula:

$E(X^2) = \sum_{i=1}^n X^2_i P(X_i)$

And replacing we got:

$E(X^2) = (23.4)^2* 0.67 +(-11.9)^2*0.33= 413.5965$

And the variance is given by:

$Var(X) = E(X^2) - [E(X)]^2$

And replacing we got:

$Var(X) = 413.5965 -(11.759)^2 =275.5105$

And finally the deviation would be:

$Sd(X) = \sqrt{275.5105}= 16.599 \%$

Step-by-step explanation:

We can define the random variable of interest X as the return from a stock and we know the following conditions:

$X_1 = 23.4 , P(X_1) =0.67$ represent the result if the economy improves

$X_2 = -11.9 , P(X_1) =0.33$ represent the result if we have a recession

We want to find the standard deviation for the returns on the stock. We need to begin finding the mean with this formula:

$E(X) = \sum_{i=1}^n X_i P(X_i)$

And replacing the data given we got:

$E(X) = 23.4* 0.67 -11.9*0.33= 11.759 \%$

Now we can find the second central moment with this formula:

$E(X^2) = \sum_{i=1}^n X^2_i P(X_i)$

And replacing we got:

$E(X^2) = (23.4)^2* 0.67 +(-11.9)^2*0.33= 413.5965$

And the variance is given by:

$Var(X) = E(X^2) - [E(X)]^2$

And replacing we got:

$Var(X) = 413.5965 -(11.759)^2 =275.5105$

And finally the deviation would be:

$Sd(X) = \sqrt{275.5105}= 16.599 \%$

The area of a rectangular dining room is 108ft squared and the length is 12ft. What is the width of the dining room?

Sveta_85 [38]

The width is 9.

Explanation: Because area is length times width, you need to divide area (108 ft) by length (12 ft) to get width. 108/12 is 9.
