I believe it would be -4/3.
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

Honestly anna made a scale drawing, in inches, of a building using a scale of 1:600. her scale drawing was 6 inches long. Greg made a scale drawing of the same building using a scale of 1:300. how long, in inches, was greg’s scale drawing.
Answer: H = 
Step-by-step explanation:
Step 1: Add h to both sides.
hx+x²+h=−h+x+h
hx+x²+h=x
Step 2: Add -x^2 to both sides.
hx+x²+h+−x²=x+−x²
hx+h=−x²+x
Step 3: Factor out variable h.
h(x+1)=−x²+x
Step 4: Divide both sides by x+1
