The weight of an organ in adult males has a bell-shaped distribution with a mean of 320 grams and a standard deviation of 40 grams. Use the empirical rule to determine the following. (a) About 99.7% of organs will be between what weights? (b) What percentage of organs weighs between 280 grams and 360 grams? (c) What percentage of organs weighs less than 280 grams or more than 360 grams? (d) What percentage of organs weighs between 200 grams and 360 grams?

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+
