Question

Select the statements that are true based on the following given information.
D = {x | x is a whole number}
E = {x | x is a perfect square < 36}
F = {x | x is an even number between 20 and 30}

The expression D ∪ E = E.
E ∪ (D ∩ F) is {25}.
F ⊂ D
(E ∩ F) is the empty set.
Set E is infinite.

Answer 1

I'm pretty sure the 1st one's right

Answer 2

pretty sure the second one's wrong

Answer 3

D = {0,1,2,3,4,5,6,.....}
E={1,4,9,16,25}
F={22,24,26,28}

Answer 4

D UNION E = E is never possible

Answer 5

F ⊂ D is true right?

Answer 6

D intersection F = NULL
E union NULL =E

Answer 7

b is wrong

Answer 8

im pretty sure the only correct one is F ⊂ D

Answer 9

F SUBSET D Right

Answer 10

because (E ∩ F) is the empty set. cant be right

Answer 11

and set e is obviously not infinite

Answer 12

E intersection F it's right

Answer 13

e intersection f is empty set. true

Answer 14

but 5^2 is 26 and that's less than 36 and in between 20 and 30

Answer 15

Set E is infinite is wrong

Answer 16

5^2 is 25 not 26

Answer 17

ooooh an even number ok nvm

Answer 18

yeah

Answer 19

ok thanks for the help!

Answer 20
