Answer:
total cost divided by no.of pieces =cost of each piece
so
10/8
=1.25
therefore option B) $1.25 is the answer...
Answer:
c. you reject a null hypothesis that is true
Step-by-step explanation:
We need to remember the following concepts
Error type I: Is an error associated to the probability of reject a null hypothesis when it is actually true
Error type II: Is an error associated of not rejecting a null hypothesis when the alternative hypothesis is the true
And the best answer for this case would be:
c. you reject a null hypothesis that is true
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
