Question

Match the following.

Given

D = {x | x is a whole number}
E = {x | x is a perfect square < 100}
F = {x | x is an even number between 10 and 20}




1. D ∩ E               A. {1, 4, 9, 16, 25, 36, 49, 64, 81}
2. D ∩ F               B. {1, 4, 9, 16, 25, 36, 49, 64, 81, 12, 14, 18}
3. D ∩ (E ∩ F)            C. {all whole numbers}
4. D ∪ (E ∩ F)       D. {16}
5. D ∩ (E ∪ F)              E.{12,14,16,18}

Answer 1

well c is one of them also b

Answer 2

D ∩ E={1, 4, 9, 16, 25, 36, 49, 64, 81, 12, 14, 18}
D ∩ F={12, 14, 16, 18}
D ∩ (E ∩ F)={1, 4, 9, 16, 25, 36, 49, 64, 81}
D ∪ (E ∩ F)={all whole numbers}
D ∩ (E ∪ F)={16}
