Surface area of solid figures

Mathematics
1 answer:
Lilit [14]2 years ago
6 0

Answer:

C. 468mm²

Step-by-step explanation:

The formula for the surface area of rectangular prism is:

A=2(wl+hl+hw)

Let's break down our variables.

L = 12mm

W = 6mm

H = 7mm + 2mm = 9mm

Now we substitute our values in the formula:

A=2((6)(12)+(9)(12)+(9)(6))

A=2(72+108+54)

A=2(234)

A=468mm^{2}

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
