Answer:
a) (iv) Poisson.
b) E(X)=V(X)=λ=4.8
c) E(Y)=24,000
V(Y)=120,000,000
Step-by-step explanation:
We can appropiately describe this random variable with a Poisson distribution, as the probability of having a pothole can be expressed as a constant rate per mile (0.16 potholes/mile) multiplied by the stretch that correspond to the county (30 miles).
The parameter of the Poisson distribution is then:
b) The expected value and variance of X are both equal to the parameter λ=4.8.
c) If we define Y as:
the expected value and variance of Y are:

The answer is C hopefully this helps

Answer:
Height = 40 cm
Step-by-step explanation:
Volume is length x height x width.
You are given Volume, Length and width, so we multiply the length and width together then divide the volume by that to find the height.
Length x width = 25 * 10 = 250 square cm.
Height = 10,000 cm^3 / 250 cm^2
Height = 40 cm
