Answer:
The probability that the demand will exceed 190 cfs during the early afternoon on a randomly selected day is
Step-by-step explanation:
Let Y be the water demand in the early afternoon.
If the random variable Y has density function f (y) and a < b, then the probability that Y falls in the interval [a, b] is
A random variable Y is said to have an exponential distribution with parameter if and only if the density function of Y is
If Y is an exponential random variable with parameter β, then
mean = β
To find the probability that the demand will exceed 190 cfs during the early afternoon on a randomly selected day, you must:
We are given the mean = β = 100 cubic feet per second
Compute the indefinite integral
Compute the boundaries
The probability that the demand will exceed 190 cfs during the early afternoon on a randomly selected day is
It is 12.5%

Factor out a '6' from '6r-36'
---> 6r-36 = 6(r-6)
The 'r-6' terms cancel out

Step-by-step explanation:
Answer:
It becomes the exact opposite
Step-by-step explanation:
imagine taking y=2x+5
and multiply it by -1
-1(2x+5)= -2x-5
y=-2x-5
