Find the range and standard deviation of the set of data.
46, 44, 49, 39, 48, 40, 42

Step-by-step explanation:

The range of a data set is the difference between the least number and highest number in the data set.

The least number in the data set is .

The highest number in the data set is .

So,range is

Standard deviation measures how spread out the values in a data set are around the mean.

Let be the mean of the set.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
