Answer:
A bi-conditional statement represents the idea of "if and only if." Its symbol is a [tex]\leftrightarrow[/tex].
Step-by-step explanation:
We have been given an incomplete sentence. We are supposed to fill in the given blank.
A _______ represents the idea of "if and only if." Its symbol is a [tex]\leftrightarrow[/tex].
We know that "if and only if" stands for bi-conditional statement, which represents either both statements are true or both are false.
The symbol [tex]\leftrightarrow[/tex] represent a bi-conditional statement.
Therefore, our complete statement would be: A bi-conditional statement represents the idea of "if and only if." Its symbol is a [tex]\leftrightarrow[/tex].
