A manufacturer of flea collars for animals injects the collars with 15 milligrams of a medicine that only acts on fleas. The manufacturer will only sell collars with 14 milligrams and no more than 16 milligrams of medicine. The following list shows the result of sampling 36 collars from an actual production run of 720 collars. A) Based on this sample, what percent of the collars would be acceptable? Explain how you got your answer. B) Based on this sample, how many collars would you expect the manufacturer to reject?

you add50 then subtracts 50 and yea thats 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

answer: 4
