<span>In order to find the standard deviation, we first have to calculate the mean (average) of the numbers. To get this we add all the numbers together and then divide by 12 since there are 12 numbers. The mean = 782. Next, we take each number and subtract the mean, taking the result and squaring it. For this we get: 6724, 2209, 10404, 11664, 729, 1764, 12544, 9, 529, 71824, 1444, 1024. Now we sum all of these up and take the average by dividing the sum by 12. Doing this we get 120868/12=10072. The last step is the take the square root of that number to get the standard deviation. The final result is 100.</span>
Hey!
The area of the circle would be 28.26 feet squared
Lets break it down:
The formula for the area is pi×radius×radius
We have the diameter, so to find the radius, we need to divide the diameter by 2. 6÷2=3
Now that we have the radius, wr can plug in our numbers: 3.14×3×3= the area, or 28.26 feet sq.
Hope this helps!
Answer:
B)
Step-by-step explanation:
For the function 
, all coordinates this line passes through should make this inequality true.
This corresponds with table B.
