Find the constant of variation if x and y vary directly and x = 6 when y= -2/3 ? a. k= 5/22 b. y=5 c. y=22/5 d. y=1/5

a.

k= 5/22

Step-by-step explanation:

b. x- 48 =120

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 %
