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.

Find the error (-8x^2y^2)^2= -64x^4y^4
ExtremeBDS [4]

Answer:

(-8)^2\neq-64

Step-by-step explanation:

Using the distributive property to expand, we have

(-8x^2y^2)^2=(-8)^2(x^2)^2(y^2)^2.

Squaring each term, we have

(-8x^2y^2)^2=64x^4y^4.

The mistake was that 8^2=64, not -64. Using the fact that 8^2=64, the right answer would be

\boxed{64x^4y^4}.
