Math Problem Statement
LaTeX: A:=:\lbrace2,4,6,8,10,12,14,16,18,20\rbrace LaTeX: B:=:\lbrace10,12,14,16,18\rbrace Which of the following is true?
LaTeX: A:=:B
LaTeX: A:\cong B
LaTeX: A:\subseteq B
LaTeX: B:\subseteq:A
Solution
Given the sets:
Let's evaluate the options:
-
: This statement is false because and do not have the same elements. Set has 10 elements, while set has only 5 elements.
-
: This symbol, when used in set theory, typically refers to isomorphism, which is not meaningful for basic set equality or subset relations. Thus, this statement is neither applicable nor true in this context.
-
: This is false because contains elements that are not in (e.g., 2, 4, 6, 8, 20).
-
: This statement is true because every element in (10, 12, 14, 16, 18) is also in .
Hence, the correct statement is:
