It is reasonable to model the number of winter storms in a season as with a poisson random variable. suppose that in a good year the average number of storms is 4, and that in a bad year the average is 6. if the probability that next year will be a good year is 0.4 and the probability that it will be bad is 0.6, find the expected value and variance in the number of storms that will occur.

answer: just subtact the units and then add the non negative : happy to

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
