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
Answer: B
Step-by-step explanation: I saw that it went -2 and then 4.5 was added on and thus verifying that B is the correct answer.

Answer: A. 
Step-by-step explanation:
To find the slope we must find the change in y over the change in x. Δ
Or rise over run.
In the graph, we have two "good" points. (0, -6) and (4,0)
So for Δy 0 to -6 = -6
So -6 goes on top 
Now Δx goes from 4 to 0 so the change would be -4.
So now it becomes 
Since there are two negatives it becomes a positive.
Or simply put,
