Answer:
area is given base is given so area of parallelogram =b x h
or 72=13 x h
or h =72/13=5.5 units
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:
x(x - 6)(x + 8)
Step-by-step explanation:
First, the GCF of these 3 terms is x.
So to separate x from this it now becomes x(x^2 + 2x - 48).
Now to factor the expression inside the parentheses easily I use "a" and "b" to make it easier.
a + b = 2 (from 2x)
a * b = -48 (from third term of expression)
a = -6, b = 8
Substitute "a" and "b" and I get: x(x - 6)(x + 8)
49.95 Would be the Registration fee because it is a number by itself, 24.72m would be the monthly payment because it is being multiplied by m, m being months.
