Find the depth of the river at 9 hours and 18 hours by seeing where the line is on the Y axis.
At 9 hours the river is 18 feet deep
At 18 hours the river is 21 feet deep.
The average rate of change is the change in Y over the change in X
The Y is the depth and the X is the time:
(21-18) / (18-9) = 3/9 = 1/3 = 0.33
The average rate of change is 0.3 foot per hour. ( Rounded to nearest tenth)

You are expected to lose $0.05 (or win -$0.05)
Step-by-step explanation:
Since the roulette wheel has the numbers 1 through 36, 0, and 00, there are 38 possible outcomes.
In this bet, you are allowed to pick 3 out of the 38 numbers. Thus, your chances of winning (P(W)) and losing (P(L)) are:

The expected value of the bet is given by the sum of the product of each outcome pay by its probability. Winning the bet means winning $11 while losing the bet means losing $1. The expected value is:

Therefore, with a $1 bet, you are expected to lose roughly $0.05
