Suppose that the annual rainfall in Ferndale, California, is known to be normally distributed, with a mean of 35.5 inches and a
erastovalidia [21]

The average annual rainfall will be more than 40.6 inches in about 2.1 percent of the years.

<h3>What is the average annual rainfall?</h3>

Generally, the equation for the probability is mathematically given as

P( X < x) = p( Z < x - \mu / \sigma)

Therefore

P( X > x) = 0.021

P( X < x ) = 1 - 0.021\\\\\p( X < x) = 0.979

P( Z < x - \mu / \sigma) = 0.979

The z score for the probability of 0.979 is 2.034, according to the table of z values.

x - \mu / \sigma \\\\x= 2.034

In the given equation, replace the values of mu and sigma with their respective values, and then solve for x.

x - 35.5 / 2.5 \\x= 2.034

In conclusion, The average annual rainfall will be more than 40.6 inches in about 2.1 percent of the years.

Please answer asap! show work!<br> 11. What is (f.g)(x)?<br> f(x) = x3 +3<br> g(x) = 2x2 + x - 1
Ksenya-84 [330]

Answer:

<u>2x⁵ + x⁴ - x³ + 6x² + 3x - 3</u>

Step-by-step explanation:

Given :

  • f(x) = x³ + 3
  • g(x) = 2x² + x - 1

Finding (f × g)(x) :

  • f(x) × g(x)
  • (x³ + 3)(2x² + x - 1)
  • 2x⁵ + 6x² + x⁴ + 3x - x³ - 3
  • <u>2x⁵ + x⁴ - x³ + 6x² + 3x - 3</u>

A = pi x (5)^2
A = pi x 25
A = 25pi cm^2

ANSWER:
B - 25pi cm^2

Hope this helps!! :)
