If RS = 44.5 and QS = 74.8, find QR.

2

=799+6876554

Step-by-step explanation:

61.4

Step-by-step explanation:

h2 = p2 + b2

(75.8)2 = (44.5)2   + b2

5745.64 = 1980.25 + b2

5745.64 - 1980.25 = b2

3765.39 = b2

61.4= b

therefore QR = 61.4

step-by-step explanation:

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 %
