Which of the following Cartesian products would give the result the set 20, 37 and 20, 11?
00:00:11.590 --> 00:00:14.940
Let’s think about what we know about Cartesian products.
00:00:15.910 --> 00:00:19.710
Cartesian products is the set A times the set B.
00:00:20.750 --> 00:00:31.120
This multiplication of the two sets creates ordered pairs, where the first element is from set A and the second element is from set B.
00:00:31.880 --> 00:00:38.560
We’ve been given the product, and we need to find the two sets that were multiplied together.
00:00:39.420 --> 00:00:45.750
We know that the first element in the ordered pair must come from set A.
00:00:46.580 --> 00:00:52.220
And that means that the first set here must be the set that includes 20.
00:00:53.350 --> 00:00:55.600
And that means we can eliminate option d.
00:00:56.620 --> 00:01:01.080
We know that the second element from the ordered pair comes from set B.
00:01:02.350 --> 00:01:08.390
And for us, that means that we have both 37 and 11 in set B.
00:01:09.410 --> 00:01:18.870
Set 20 multiplied by set 37, 11 would give the result of the order pairs 20, 37 and 20, 11.
