Paisley randomly surveys 48 teachers about the type of car they drive.

Histogram where the x axis represents SUV, sedan, and truck. The y- axis runs from zero to thirty at intervals of five. The histogram for SUV is at the point fifteen on the y- axis. The histogram for sedan is at the point twenty six on the y- axis. The histogram for truck is at the point seven on the y- axis.

If Paisely randomly surveys another 300 teachers, how many would she expect to drive an SUV?

54

step-by-step explanation:

6x9

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %  

step-by-step explanation:

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
