Does anyone get this??
Harlamova29_29 [7]

Answer:

the answer is 12m

Step-by-step explanation:

u know the side c and side B.

C=15m but u have to square it which is 225

B=9m but u have to square it which is 81. then subtract 82 from 225.which will give u 144 which is a perfect square route of 12

Randolph is trying to find the equation of a line parallel to y = x − 6 in slope-intercept form that passes through the point (−
bekas [8.4K]
An equation of a line parallel to y=x-6, must have the same slope.

In this equation:
y=mx+b                        (slope-intercept form)
m is the slope:

The slope of the equation y=x-6 is m=1  (the number beside "x").

Now we have a point (-1,5) and the slope m=1.

Point-slope form of a line:
y-y₀=m(x-x₀)
so:
y-5=1(x+1)

answer: the equation of the line in point-slope form is :
y-5=1(x+1)

And the eqution of this line in slope-intercept form is:
y=x+6

y-5=(x+1)
y=x+1+5
y=x+6

Let X1, . . . ,Xn be an i.i.d. random sample from a N(0, 1) population. Define Y1 = 1 n n X i=1 Xi , Y2 = 1 n n X i=1 |Xi| . Cal
nalin [4]

For each 1\le i\le n, E[X_i]=0, so that

\displaystyle E[Y_1]=E\left[\frac1n\sum_{i=1}^nX_i\right]=\frac1n\sum_{i=1}^nE[X_i]=0

Meanwhile,

\displaystyle E[Y_2]=\frac1n\sum_{i=1}^nE[|X_i|]

Each of the X_i have PDF

f_{X_i}(x)=\dfrac1{\sqrt{2\pi}}e^{-x^2/2}

for x\in\Bbb R. From this we get

E[|X_i|]=\displaystyle\frac1{\sqrt{2\pi}}\int_{-\infty}^\infty|x|e^{-x^2/2}\,\mathrm dx=\sqrt{\frac2\pi}\int_0^\infty xe^{-x^2/2}\,\mathrm dx=\sqrt{\frac2\pi}

\implies E[Y_2]=n\sqrt{\dfrac2\pi}
