ANSWER #5

**Analyze and answer the following statements.**

1. **State whether each bi-conditional is true or false.**
   a. \( x > 7 \) if and only if \( x > 6 \)
   b. \( x + 5 > 7 \) if and only if \( x > 2 \)

2. **Use \( p, q, \) and \( r \) as defined in Example 6. Write the following symbolic statements in words:**
   a. \( p \leftrightarrow \sim r \)
   b. \( \sim q \leftrightarrow \sim r \)

3. **Write the negation of each conditional statement.**
   a. If I finish the report, I will go to the concert.
   b. If the square of \( n \) is 25, then \( n \) is 5 or -5.

4. **Write each of the following in its equivalent disjunctive form.**
   a. If I don’t move to Georgia, I will live in Houston.
   b. If the number is divisible by 2, then the number is even.

5. **Construct a truth table for \([p \land (p \rightarrow q)] \rightarrow q\).**

6. **Determine the truth value of each of the following conditional statements.**
   a. If \( 4 \geq 3 \), then \( 2 + 5 = 6 \)
   b. If \( 5 > 9 \), the \( 4 > 9 \)
   c. If Tuesday follows Monday, then April follows March.

7. **Identify the antecedent and consequent in each of the following conditional statements.**
   a. If I study for at least 6 hours, then I will get an A on the test.
   b. If I get the job, I will buy a new car.
   c. If you can dream it, you can do it.
