In Exercises 7-10, let \(p\) and q represent the following simple statements: \(p:\) I study. q: I pass the course. Write each compound statement in symbolic form. I study or I pass the course.

Use Euler diagrams to determine whether each argument is valid or invalid. All insects have six legs. No spiders are insects. Therefore, no spiders have six legs.

Let \(p\) and \(q\) represent the following statements: \(p: 4+6=10\) \(q: 5 \times 8=80\) Determine the truth value for each statement. \(\sim p \wedge \sim q\)

Determine whether or not each sentence is a statement. The average human brain contains 100 billion neurons.

Use a truth table to determine whether the symbolic form of the argument is valid or invalid. $$ \begin{aligned} &p \rightarrow q \\ &\frac{q \rightarrow p}{\therefore p \wedge q} \end{aligned} $$

Let \(p\) and q represent the following simple statements: \(p:\) I study. q: I pass the course. Write each compound statement in symbolic form. I pass the course or I study.

Determine whether or not each sentence is a statement. There are \(2,500,000\) rivets in the Eiffel Tower.

Write the negation of each conditional statement. If there is a tax cut, then all people have extra spending money.

Use Euler diagrams to determine whether each argument is valid or invalid. All humans are warm-blooded. No reptiles are human. Therefore, no reptiles are warm-blooded.

Use a truth table to determine whether the symbolic form of the argument is valid or invalid. $$ \begin{aligned} &(p \rightarrow q) \wedge(q \rightarrow p) \\ &\frac{p}{\therefore p \vee q} \end{aligned} $$
