(10 points)





A.



(20,20)





B.



(30,30)





C.



(55,60)





D.



(30,60)

Answer 1

I dont see the answer then , it is none of these

Answer 2

This question is confusing.
M = {20,20,55,60} are you sure that is 20,20,55,60?
Secondly in maths MxN stands for some kind of multiplication. Are you sure that there is an x in between?

Answer 3

MxN stands for the cartesian product of M and N, thats fine

Answer 4

the set of all pairs using the first member from M and second member from N

Answer 5

but you should check if theres a typo in the question.

Answer 6

in your set M, you have 20 twice. that seems odd

Answer 7

okay

Answer 8

A = {1, 2, 3}
B = {400, 500, 600}

A x B = {(1,400), (2,400), (3,400),
(1,500), (2,500), (3,500),
(1,600), (2,600), (3,600)}

Answer 9

I dont think trejackson is studying Cartesian product. I believe this question is just stated poorly.
Maybe Im wrong, than so sorry

Answer 10

all the options are co-ordinate pairs

Answer 11

For this question you will have to determine which of the coordinate pairs (from the options provided) is formed in the cartesian product

Answer 12

(either there is a typo in the question)
or
E. None of the above
