The area is 84.
What I do it cut the polygon into something easier like a square and rectangle.
Rectangle: 6•12=72
Square: 4•3=12
Add them together and you have 84
Answer:
-50 cents
Step-by-step explanation:
The "Winnings" random variable has values -1 and 499
The associated probabilities are P(-1)= 999/1000; P(499)=1/1000
-----------------------------
Expected Value = -1(999/1000) + 499(1/1000) = -500/1000 = -50 cents
FOIL
x^2+11x-9x-99
x^2+2x-99
Plugging in the values, we get 7(6)-4=42-4=38.
