Weegy: Union and intersection are operations in the algebra of sets.
User: 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}
D (E F) is {all whole numbers}.
The expression D E is {1, 4, 9, 16}.
The expression D (E F) is 25
The expression D F is {12, 14, 16, 18}.
(E F) is the empty set.
(More) 3
Based on the given information:
1. D (E F) is {all whole numbers}. (True)
2. The expression D E is {1, 4, 9, 16}. (True)
3. The expression D (E F) is 25. (True)
4. The expression D F is {12, 14, 16, 18}. (False)
5. (E F) is the empty set. (True)
Therefore, the true statements are:
1. D (E F) is {all whole numbers}.
2. The expression D E is {1, 4, 9, 16}.
3. The expression D (E F) is 25.
5. (E F) is the empty set.
