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
Therefore
The z score for the probability of 0.979 is 2.034, according to the table of z values.
In the given equation, replace the values of mu and sigma with their respective values, and then solve for x.
In conclusion, The average annual rainfall will be more than 40.6 inches in about 2.1 percent of the years.

Answer: second one, then the 4th one
Step-by-step explanation:
2. The area for a circle is as follows:
A = π
The radius of the circle is 4 in, so we plug that into the equation.
A = π (4
)
4
= (4 in.)(4 in.) = 16
A = 16π
This is the area for the whole pizza, so divide that by 2 to get the area of the pepperoni
a) 8π
For the bacon, we can just divide the value we already have by 2, since it is half the area of the pepperoni
b) 4π
3. This question is asking for the circumference, whose equation is as follows:
C = 2 π r
We can use the area formula, A = π
to find the radius of this circle
36π = π
Divide both sides by π:
36 =
Square root both sides:
r = 6 in.
Plug in this value to the circumference formula, C = 2 π r
C = (2)(π)(6 in.)
Your final answer is:
C = 12π in.
Answer:
Yes.
Step-by-step explanation:
You can use the Pythagorean theorem to figure this out.
5²+12²=13²
25+144=169
169=169
You can also look at the bottom left corner, which is a right angle. All triangles containing right angles are right triangles.
You can also base your answer off of the fact that triangles are kind of like <u>G</u>oogle: They're always right. (jk no that's not true neither are always right)

Answer: B) 2.9 approximately</h3>
==================================================
Explanation:
The weird or fancy looking E symbol is the greek uppercase letter sigma. It is effectively the english version of S to represent summation. So we add up all the 
terms to get this. Luckily this has already been done for us in the table where they wrote "sum = 34", so 
From here, we substitute this into the formula, along with n = 5 since there are 5 items in the original list
So,
This computes the sample standard deviation. To get the population standard deviation, you'd basically change the "n-1" to simply "n", and the rest of the formula is identical.
