When simplifying a fraction, whatever you do to the top has to be the same as what you do to the bottom. if nicholas simplified the numerator by 5 he has to simplify his denominator by 5. if did that correctly, 20/5=4 and 30/5=6. however, he can still simplify. taking the new fraction 4/6 you can divide both the numerator and denominator by 2. 4/2=2 and 6/2=3. nicholas would now have the fraction 2/3

The random variable X has the following probability mass function.X -1 0 2 6 7P(x) 0.3 0.1 0.3 0.2 0.1Answer the next 4 question
olga2289 [7]

Answer:

Step-by-step explanation:

Given that X has the following pdf.

x -1 0 2 6 7 Total

P(X) 0.3 0.1 0.3 0.2 0.1 1

xP(X) -0.3 0 0.6 1.2 0.7 2.2

x^2P(X) 0.3 0 1.2 7.2 4.9 13.6

     

Var(x) 13.6-2.2^2  8.76    

Std dev   2.959729717    

5) P( -1 < X ≤ 2) = P(0)+P(2)\\= 0.1+0.3=0.4

6. Find the cumulative distribution function F(x) and calculate F(3.2) =

x -1 0 2 6 7

P(X) 0.3 0.1 0.3 0.2 0.1

F(x) 0.3 0.4 0.7 0.9 1

F(3.2) = P(X<3.2) = ___F(X<6) = 0.7__________

7. E(X) = ______2.2_____

8. Var(X) = ____8.76______

Compute the following products.<br> (4x+5)(4x−5)<br><br> (4x+5)2
bearhunter [10]
(4x+5)(4x-5) is equal to 16x^2+20x-20x-25
The positive and negative 20x cancel out
Leaving you with: 16x^2 - 25
[S/N this is a pattern that shows up a decent amount. Whenever you have something that looks like (x^2-y^2) it factors out to (x+y)(x-y). It might be helpful to remember]

The next one, (4x+5)2, just follows the distributive property. Multiply both components within the parentheses bye the coefficient of 2: 8x+10

Carlos performed a transformation on trapezoid EFGH to create E′F′G′H′, as shown in the figure below:
Nataliya [291]

Answer:

90° clockwise rotation or 270° anticlockwise rotation

Step-by-step explanation:

(x,y)=(y,-x)

<em>E(-6,-4)=E'(-4,6)</em>

<em>F(-4,-4)=F'(-4,4)</em>

<em>G(-2,-6)=G'(-6,2)</em>

<em>H(-7,-7)=H'(-7,7)</em>

Therefore, E prime is (-4,6), F prime is (-4,4), G prime is (-6,2) and H prime is (-7,7).
