A company had 80 employees whose salaries are summarized in the frequency distribution below. Find the standard deviation. Salary (Dollars) Employees 5,001-10,000 19 10,001-15,000 14 15,001-20,000 12 20,001-25,000 16 25,001-30,000 19

what is the answer?

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4
