Acircle has an arc whose measure is 80° and whose length is 88π, what is the diameter of the circle?

396

Step-by-step explanation:Arc length = radius * angle in radians

you know radius = Diameter/2 = D/2

80 deg = (80pi/180) rad

then,

88 pi = (D/2) * (80 pi /180)

sloving for D

D = 396

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:

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
