Answer:

x=0

Step-by-step explanation:

Assuming the two sides are equal length

2x+15 =x+15

Subtract 15 from each side

2x =x

Subtract x from each side

2x-x = x-x

x=0

Step-by-step explanation:

<em>Given</em><em>, </em>

<em>RSTU</em><em> </em><em>is</em><em> </em><em>a</em><em> </em><em>parallelogram</em><em>, </em>

<em>so</em><em>,</em><em> </em><em>we</em><em> </em><em>need</em><em> </em><em>to</em><em> </em><em>find</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>x</em><em>,</em>

<em>let's</em><em> </em><em>find it</em><em>, </em>

<em>2</em><em>x</em><em>+</em><em>1</em><em>5</em><em> </em><em>=</em><em> </em><em>x</em><em>+</em><em>1</em><em>5</em><em> </em><em> </em><em> </em><em>(</em><em>opposite</em><em> </em><em>side of</em><em> </em><em>parallelogram</em><em> </em><em>are</em><em> </em><em>equal</em><em> </em><em>and</em><em> </em><em>parallel</em><em>)</em>

<em>2</em><em>x</em><em> </em><em>-</em><em> </em><em>x</em><em> </em><em>=</em><em> </em><em>1</em><em>5</em><em>-15</em>

<em>x</em><em>=</em><em>0</em>

<em>Therefore</em><em>, </em><em>the</em><em> </em><em>value of</em><em> </em><em>x</em><em> </em><em>is</em><em> </em><em>0</em><em>.</em>

<em>If</em><em> </em><em>you</em><em> </em><em>have</em><em> </em><em>doubt</em><em>.</em><em> </em><em>then</em><em> </em><em>let's</em><em> </em><em>clear</em><em> </em><em>it</em><em> </em><em>by</em><em> </em><em>putting</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>x</em><em>.</em>

<em>so</em><em>,</em><em> </em><em>2</em><em>×</em><em>0</em><em>+</em><em>1</em><em>5</em><em> </em><em>=</em><em> </em><em>0</em><em>+</em><em>1</em><em>5</em>

<em>1</em><em>5</em><em>=</em><em>1</em><em>5</em><em> </em><em>{</em><em>as</em><em> </em><em>already</em><em> </em><em>said</em><em> </em><em>that</em><em> </em><em>the</em><em> </em><em>sides</em><em> </em><em>are</em><em> </em><em>equal</em><em>}</em>

<em>proved</em><em>.</em><em>.</em>

<em>so</em><em>,</em><em> </em><em>the</em><em> </em><em>value of</em><em> </em><em>x</em><em> </em><em>is</em><em> </em><em>0</em><em>.</em>

Charra [1.4K]
I think the answer is 12.6 extra gigabytes because:

20 - 51.50 = 31.50

31.50 / 2.50 = 12.6

What is the domain of the function graphed below?
I am Lyosha [343]

Answer:

x < 7

Step-by-step explanation:

the domain is the number range or interval of x the function is defined for to generate a y-value.

the graph shows that the y-values continue with x-values to the right up to but not including 7 (the empty dot says "excluding"). and with x- values to the left to negative infinity.

x=-1 is not a problem, because while for the left part of the function it is not included, but for the right part it is.

so, it is fully defined for all x < 7.

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 \%
