Each of these statements are part of True/False game. Which statement is correct?
sergey [27]

Answer:

E. (The function is exponetial)

Step-by-step explanation:

We look at the output values and subtract them from their previous value to see it's slope.

6-2 = 4

12-6 = 6

4 ≠ 6, meaning that the slope is not constant.

4 < 6, meaning that the slope is increasing, meaning the function is exponential.

Bob and will toss two coins. if both coins come up heads, bob pays will $6. will pays bob $2 otherwise. what is the expected val
Helga [31]
Each coin has a head and a tail, therefore when you toss two coins, you have 4 possible outcomes. You have two heads in only one of these outcomes, while the other three have at least one tail.

The expected value of the game is the price paid/gained times the probability of loss/victory:

E = (1 / 4) · (-6) + (3 / 4) · (2)
   = -3 / 2 + 3 / 2
   = 0

Bob expects to tie with Will.
