Answer:
The standard deviation of the data set is
.
Step-by-step explanation:
The Standard Deviation is a measure of how spread out numbers are. Its symbol is σ (the greek letter sigma)
To find the standard deviation of the following data set

we use the following formula

Step 1: Find the mean
.
The mean of a data set is the sum of the terms divided by the total number of terms. Using math notation we have:


Step 2: Create the below table.
Step 3: Find the sum of numbers in the last column to get.

Step 4: Calculate σ using the above formula.

The primitive function for
is given by it's indefinite integral.
To calculate it, recall:


Let's begin


To find the costant, we just need to use the fact that 

Therefore,

Answer:
x = 30.0462
Step-by-step explanation:
- Divide each side by 3 to cancel out the 3 next to x. It should now look like this: x = 30.0462

Answer:
The formula for calculating the circumference of a circle is 2*pi*r. Because pi does not have an end, we'll use 3.14, since that is the approximate value of pi.
2*6*3.14 = 37.68
The outer rim of the pool is about 37.68 meters long
Step-by-step explanation:
It’s probably 40 because it says about how long not exactly.
