55.0 inches of on average annually with a standard deviation of 5 inches. Assume the amount of annual rainfall in the Everglades to follow normal distribution. What is the probability that it will rain less than 45 inches this year?

the probability that it will rain less than 45 inches this year is 0.023

Step-by-step explanation:

Assuming the amount of annual rainfall in the Everglades to follow normal distribution, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = the amount of annual rainfall.

µ = mean

σ = standard deviation

From the information given,

µ = 55 inches

σ = 5 inches

We want to find the probability that it will rain less than 45 inches this yearh. It is expressed as

P(x < 45)

For x = 45,

z = (45 - 55)/5 = - 2

Looking at the normal distribution table, the probability corresponding to the z score is 0.02275

P(x < 45) = 0.023

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
