Question

If W = {1, 2, 3, 4 …} and subset Z = {positive odd integers}, what is Z'?

Answer 1

Z' are the elements which aren't present in Z.

Answer 2

that is an odd way to define sets

Answer 3

Z'= everything in W but kick out everything in Z

Answer 4

W and Z are used for their own specific sets, they shouldnt try to confuse the issue

Answer 5

The answes can be A= {1, 2, 3, 4 …} B= { } C={5, 6, 7, 8 …} D= {2, 4, 6, 8, …}

Answer 6

its algebra 1 ......

Answer 7

ie take the positive integers (which are in W) and erase all of the odd positive integers (which are in Z) to get

Z' = {2, 3, 4, 6, 8, ....}

so this is the set of positive even numbers

Answer 8

Z'={2,4,6,8,..}
darn it

Answer 9

and trying to relate A,B,C, and D to Z' is bad form as well

Answer 10

1000 monkeys at 1000 typewriters for 1000 years :)

Answer 11

good point, they should have made the set Z be Y or something

Answer 12

if Z is defined already as {odd numbers}

then it doesnt matter what they define W to be since Z' is simply {not the odd numbers}

Answer 13

but i guess if Z < W it would be proper lol

Answer 14

exactly you beat me to it lol

Answer 15

i may be dumb, but I ant smart ;)
