Kipish [7]

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) = ΣY^{2}p − (μ x μ)

E(Y) = (2 x 0.25) +(6 x 0.25) + (0.5 x (-3)) = $0.5

Var(Y) = (2^{2}\\x 0.25) + (6^{2} x 0.25) +(-3^{2} x 0.5) - (0.5^{2})

       = 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

Solve x + 3y = 9<br> 3x – 3y = -13 (1 point)
Mariana [72]

Answer:

The values of x and y to the given equations are x=-1 and y=\frac{10}{3}

The solution is (-1,\frac{10}{3})

Step-by-step explanation:

Given equations are x+3y=9\hfill (1)

and 3x-3y=-13\hfill (2)

to solve the given equations by elimination method :

Adding the given two equations (1) and (2) we get

x+3y=9

3x-3y=-13

_______________

4x=-4

x=-\frac{4}{4}

Therefore x=-1

Now substitute the value x=-1 in equation(1) we get

(-1)+3y=9

3y=9+1

y=\frac{10}{3}

Therefore the values of x and y to the given equations are x=-1 and y=\frac{10}{3}

The solution is (-1,\frac{10}{3})
