Step-by-step explanation:
Note: If you have any queries related the answer please do comment. I would be very happy to resolve all your queries.
Firstly we will make PMF
For X=0, P=(4/5)^3=64/125
For X=1, P=C(3,1)*(1/5)*(4/5)^2=3*16/125=48/125
For X=2, P=C(3,2)*(1/5)^2*(4/5)=3*4/125=12/125
For X=3, P=C(3,3)*(1/5)^3=1/125
So,
E[X^2]=1*48/125+2^2*(12/125)+3^2/125=0.84
E[X]=48/125+12/125*2+1/125*3=0.6
So,
E[X]^2=0.36
Answer:
X intercept is (-1,0)
Y intercept is (0,2)

1. Yes
2. A-2x
Hope this helps also I did this question and got it correct
Answer:
x = 1°
Step-by-step explanation:
Bisection means splitting the angle in to 2
So that means 4x-1 = 2x+1
4x-1 = 2x +1
4x = 2x + 2
2x = 2
x = 1°

The formula for finding circumference is C=2*pi*r. So C is the circumference that you are trying to find. Pi is 3.14. And r is the radius. Now, it does not tell you directly what the radius is, but the diameter of a circle is basically how far across is it. So in this case, 14. The radius of a circle is half of it's diameter, so half of 14 is 7. So, multiply 2*3.14*7, to get the circumference. You get 43.96.
