x-y=5
Step-by-step explanation:
If a line has a slope of 1, its function can be write as x-y=c
insert point (7,2),t then we can find out the constant c=5, so the equation of this line is x-y=5
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
