The mean of the data is 11
now we find the difference between the mean and each number
1, 2, 3, 0.5, 0.25, 1.25, 1.
now we square the numbers
1, 4, 9, 0.25, 0.0625, 1.
now we find the mean of the new numbers
which is 2.1875
2.1875 is your standard deviation.

Answer: three dimensional figure and plane.
Step-by-step explanation:
A cross section is the intersection between a (three dimensional figure) and also a (plane).
When an object is being cut straight, the shape that we get is referred to as the cross section. We should note that several parallel cross sections will be firmed when we cut a particular object into slices.
The easiest way to do it is to make the numbers into decimals. All you need to do is divide them.
To convert 3/4 into a decimal just divide 3 by 4.
3 / 4 = .75
To get 5 1/2 into a decimal just ignore the 5 for now and divide the 1 by 2.
1 / 2 = .5
Now add the 5 back on and you have 5.5
So far you have converted the equation from (3/4) / 5 1/2 to .75 / 5.5
Now just divide .75 by 5.5
.75 / 5.5 = 1.136 with the 36 repeated
