Answer:

- $0.053

Step-by-step explanation:

Bet fee = $1

Probability of red = 18 / 38

Probability of black = 18/38

Probability of green = 2 / 38

x : ____1 _____ - 1 _____ - 1

P(x) : __ 18/38___ 18/38____ 2/38

Mean or expected value, E(X) = Σx*p(x) = (18/38) * * (-18/38) * (-2/38)

E(X) = - 0.052631

E(X) = - $0.053

Find the surface area of this triangular prism.

vesna_86 [32]

Answer:

Step-by-step explanation:

A=Area

Using the formulas

$A= 2A_{b} +(a+b+c)h\\A_{b} = \sqrt{s(s-8)(s-10)(s-6)} \\s= \frac{8+10+6}{2}$

Solving for A

$A=ah+bh+ch+\frac{1}{2}*\sqrt{-a^4+2(ab)^2+2(ac)^2-b^4+2(bc)^2-c^4}$

$A=8(2)+10(2)+6(2)+\frac{1}{2}*\sqrt{-8^{4} +2*(8*10)^{2} +2*(8*6)^{2}-10^{4} +2*(10*6)^{2}-6^{4} }$ $A=96$
