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
Your answer is 5.25 thank thats the answer im not 100%sure but im like 97%
Answer:

Step-by-step explanation:
To factor by grouping, first divide the polynomial into 2 groups with parentheses.


Factor the greatest common factor (GCF) out of both binomials.
For the first binomial, the GCF is x.

For the second binomial, the GCF is 2.

Factor out the common binomial which is (x-5).

The factorized form of x²-5x+2x-10 is (x+2)(x-5)
Answer: X is 0.4
Explanation: I typed 5/2 x a bunch of random numbers and decimals on a calculator until I tried 0.4 and when I typed 5/2 x 0.4 on the calculator it said 5/2 x 0.4 = 1.
Klye would receive $0.77 back as change. You have to subtract $20.00 - $19.23
