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:
B, 150
Step-by-step explanation:
use pythagorean theorem, the sides of the triangle are 120 and 90, so when u square them and add them together, you get 120^2 +90^2 = 22500
square root 22500 to find the hypotanuse which is the length from one corner to another. the anwser is 150m which is b
