2/3(x−7)=−2

What is X

  x = 4

Step-by-step explanation:

  2/3(x -7) = -2 . . . . . given

  x -7 = -3 . . . . . . . . . multiply both sides by 3/2

  x = 4 . . . . . . . . . . . . add 4 to both sides

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 %
