A sphere with radius r has surface area 4\pi r^2. Divide the radius by 6 and you get a surface area of 4\pi\left(\dfrac r6\right)^2=\dfrac4{36}\pi r^2, so that the final surface area is divided by 36.

How do I construct a sample data set for which n=7, x=9(x bar), and s=0?
JulijaS [17]
When the standard deviation = 0, there is no deviation at all. So the numbers are all the same. And there are seven of them. And the average is nine. 
So the sample data set would just be seven 9s.

irga5000 [103]

Answer:

D. 850 square foot

Step-by-step explanation:

Area of a space is the length

multiply by the width

The area for the kitchen, dining, office and sunroom will be calculated independently and added together.

Note the word "and the office and sunroom are each 10 feet by 10 feet"

Kitchen area = 10 ft x 15ft= 150sqft

Living/Dining area = 20ftx25ft= 500sqft

Sunroom = 10ftx10ft= 100sqft

Office= 10ftx10ft=100sqft

Therefore total surface area is the cumulative of the 4 areas

150sqft+500sqft+100sqft+100sqft= 850sqft
