Solution :
a).
Now, if X = Y, then :
Then, E[X|Y] = x = y
So,
= 0
Therefore, this statement is TRUE.
b). If X = Y , then Var (X) = Var (Y)
And as Var (X|Y) = 0, so Var (X|Y) ≠ Var (X), except when all the elements of Y are same.
So this statement is FALSE.
c). As defined earlier,
So, this statement is also TRUE.
d). The statement is TRUE because .
e). FALSE
Because,
Answer:
f(x) = -2x + 11
Step-by-step explanation:
okay so if f(-2) = 15 and f(1) = 9
i used desmos to picture it and i got f(x) = -2x + 11
because f(-2) = -2(-2) + 11 = 4 + 11 = 15 so f(-2) = 15
and f(1) = -2(1) + 11 = -2 + 11 = 9 so f(1) = 9
