Answer:
E(Y) = $0.5
Var(Y) = 14.25
you should pay the same amount $0.5
Step-by-step explanation:
E(Y) = = Σ(YP)
P = probability of each outcomes.
Var(Y) = Σ
p − (μ x μ)
E(Y) = (2 x 0.25) +(6 x 0.25) + (0.5 x (-3)) = $0.5
Var(Y) = (
x 0.25) + (
x 0.25) +(
x 0.5) - (
)
= 14.5 - 0.25
Var(Y) = 14.25
for the difference between the payoff and cost of playing to have mean 0, you should pay the same amount $0.5
A higher positive slope means a steeper upward tilt to the curve, which you can see at higher output levels. A negative slope that is larger in absolute value (that is, more negative) means a steeper downward tilt to the line.
1. Common ratio is 5
2. 47
3. I believe the answer is -18, though you might want a second opinion on it to make sure it's correct.
Hope this helped! Good luck! :)
Is this a typo? What is the question exactly?
Answer:
(8,-3) is 11 and (4,-7) is 11
Step-by-step explanation:
for both all you have to do is subtract
EX. 8-(-3) = 11
