Answer:

Step-by-step explanation:
The rate of change of the function f(x) from point
to point
can be calculated using formula

Given

From the graph of the function

So, the rate of change is

To calculate expected value,
We can add up the probability of all possible events.
The 2 possible events are either winning $50 or losing the prize, which is $ - 50
Expected value =
50 x 40 % + (-50) x 60%
= $-10
So the answer is $-10
Step-by-step explanation:
apply Pythagorean theorem. if a^2 + b^2 = c^2 then
b = √(15^2 - 9^2) = 12.
12 is answer
