Answer:
162.4
Step-by-step explanation:
A= 8 * side length * apothem/2
A = 8* 5.8 * 3.5
A = 162.4

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis.
According to the data of the statement we have the following points:

We found the slope:

Thus, the equation is of the form:

We substitute one of the points and find b:

Finally, the equation is:

Answer:
 The probability that the sample mean will lie within 2 values of μ is 0.9544.
Step-by-step explanation:
Here
-  the sample size is given as 100
-  the standard deviation is 10
The probability that the sample mean lies with 2 of the value of μ is given as 
                                             
Here converting the values in z form gives

Substituting values

From z table

So the probability that the sample mean  will lie within 2 values of μ is 0.9544.
