Jose takes 120 minutes to weed 6 equal rows of vegetable plants in his garden. What is his unit rate

20 minutes per row

Step-by-step explanation:

Divide the total time by the total number of rows to find the amount of time for one row

6r= 120

Divide each side by 6 to isolate the variable (r= number of rows)

r= 20

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 %
