Answer:
1. The data value must be less than the mean.
Answer:
Step-by-step explanation:
Firstly you must understand you want to get the value of y.
So put in values into equation which make x.
To understand here lets look at y = 0
if y is to be 0 then x is 3.
If we substitute this value into equation (B) we get the result.
Now we have identified our answer, all is left is to substitute all other values of x and see if y are true.
So , we can see B is the answer
Let R be the greater radius and r be the smaller radius
A) Area of the sidewalk = R^2 - r^2 - This can be the expression
B) = 3.14
=(R^2-r^2)
=(11^2-9^2)
=(121-81)
=*40
That was the simplified expression
Answer = 3.14 * 40 = 125.6m^2
