Answer:
- 5
Step-by-step explanation:
Probability of a coin toss : (H, T)
With probability of 0.5 each
X : ____100 ____ - 110
P(x) :___ 0.5 ____ 0.5
Expected value ; E(X) = ΣX*p(X)
E(X) = (100 * 0.5) + (-110 * 0.5)
E(X) = 50 - 55
E(X) = - 5
Expected value = - 5
To determine if the given points are on the graph of the function, substitute the x- coordinate into the equation and if the value is equal to the y-coordinate then it is on the graph
(0, - 16 ) : f(0) = 0 + 1 = 1 ≠ - 16 → No
(- 1, - 1) : f(-1) = 16 + 1 = 17 ≠ - 1 → No
(1, 256 ) : f(1) = - 16 + 1 = - 15 ≠ 256 → No
400 - 200 = 600.
282 - etc. etc.
Answer: D. 84 ft^2
Step-by-step explanation: The area of a trapezoid is (a+b)/2 x h. A and B are the bases, and h is the height. Plug in the numbers.
(8+16)/2 x 7 = 84
Your answer would be 84 ft^2. D.
