The variance of a distribution is the square of the standard deviation
The variance of the data is 2.2
<h3>How to calculate the variance</h3>
Start by calculating the expected value using:
So, we have:
This gives
Next, calculate E(x^2) using:
So, we have:
The variance is then calculated as:
So, we have:
Approximate
Hence, the variance of the data is 2.2

Answer: You simply square the linear scale factor 6 and we get 6^2 = 6*6 = 36
You can think of a square with sides of 2 by 2, so the area is 4 If you multiply each dimension by 6, then the square is now 12 by 12 and the new area is 144.

Answer:
The average rate of change is 10.
Step-by-step explanation:
Since the average rate of change is the slope of a line, you'd solve this problem by finding the slope.
First, you can start by using the method.
Plug in the points (0,10) and (1,20).
Therefore your answer is 10.
