If |x| = 7 and |y| = 13, then which of the following could be equal to x + y?

Answer shown from explanation

Step-by-step explanation:

|x| means modulus of x such that positive or negative value of x evaluates to a positive value.

|x| = 7 is the same as x = -7 and x = 7

Similarly,

|y| = 13 is the same as y = -13 and y= 13;

Hence the possible values are;

7+13= 20

7-13= -6

-7-13= -20

-7 + 13 = 6

75

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 %
