Consider that x = 5 and y = 7. Which statement is true about x + y? A)The sum of x and y is a rational number. B)The sum of x and y is an imaginary number. C)The sum of x and y is an irrational number. D)The sum of x and y is neither rational nor irrational.

The answer is 12

Step-by-step explanation:

because 7 plus 5 is 12

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 %
