Question

Insert n or U to make the statement true.

{8,12,16,20}_ {1,8,9,12,15} = {8,12}
Which symbol in the blank to make the statement true.
A) U
B) ∩
C) U or ∩

Answer 1

The symbol to insert in the blank to make the statement true is '∩' which represents the intersection of two sets; the intersection of the given sets is {8,12}.

Step-by-step explanation:

To make the statement {8,12,16,20} _ {1,8,9,12,15} = {8,12} true, we need to determine which symbol (n or U) to insert in the blank. The symbol 'n' represents the intersection of two sets, which includes all elements that are common to both sets. The symbol 'U' represents the union of two sets, which includes all distinct elements from both sets. In this case, the intersection of the two sets is indeed {8,12} because those are the only elements they have in common. Therefore, the correct answer is B) ∩, making the statement {8,12,16,20} ∩ {1,8,9,12,15} = {8,12} true.
