Answer:
A. False
B. False
C. False
D. True
Step-by-step explanation:
A. False
Remember that E[aX+b] = aE[X] + b, therefore the equality would be true only if E[X] = 1.
B. False
Remember that
.
C. False
In other words they are telling you in words that
, that is false because ![V[X+b] = V[X]](https://tex.z-dn.net/?f=V%5BX%2Bb%5D%20%3D%20V%5BX%5D)
D. True
That is a property of the expected value E[X+b] = E[X]+b
Let's see this original ewuation:
![x-y=11](https://tex.z-dn.net/?f=x-y%3D11)
1) Substitute 4 in for x:
![4-y=11](https://tex.z-dn.net/?f=4-y%3D11)
2)Subtract 4 from both sides. This cancels out four.
![(4-4)-y=11-4](https://tex.z-dn.net/?f=%284-4%29-y%3D11-4)
3)Cancel:
![-y=7](https://tex.z-dn.net/?f=-y%3D7)
4)Multiply both sides by negative 1:
![-1*-y=11*-1 \\ y=-11](https://tex.z-dn.net/?f=-1%2A-y%3D11%2A-1%20%5C%5C%20y%3D-11)
