Answer:
3.96
Step-by-step explanation:
Standard Deviation quantifies how diverse the values of your data set are and is useful in determining how your numbers are different from each other.
Step 1: Collect your data to form a data set from which you wish to calculate a standard deviation.
5 9 17 11 8 11 16
Step 2: Calculate the mean of the data set;
5 + 9 + 17 + 11 + 8 + 11 + 16 = 77
Mean = 77 / 7
Mean = 11
Step 3: Subtract the mean from your data set and square the differences, continue with each number on your data set;
5 - 11 = (-6)² = 36
9 - 11 = (-2)² = 4
17 - 11 = (6)² = 36
11 - 11 = (0)² = 0
8 - 11 = (-3)² = 9
11 - 11 = (0)² = 0
16 - 11 = (5)² = 25
Step 4: Find the mean of the differences;
36 + 4 + 36 + 0 + 9 + 0 + 25 = 110
Mean = 110 / 7 = 15.71
Step 5: Take the square root of the Mean above to find the standard deviation;
²√15.71 = 3.96
Answer:
scale factor= 4.7
Step-by-step explanation:
47/10= 4.7
32.9/7= 4.7
28.2/6= 4.7
To figure out the scale factor for the smallest to the largest triangle, divide the larger number by the smaller number (of the same side).
If you wanted to get the scale factor of the largest to smallest triangle, you would just do the opposite.
ex. 10/47, 7/32.9...
