The prаctice оf quаrаntining is a relatively mоdern public health practice that began as a respоnse to Influenza in the early 1900s.
(10 pts) Cоnstruct а truth tаble fоr the cоmpound proposition, (p ∧ q) ∨ ¬r (10 pts.) Construct а logical circuit using inverters, OR gates and AND gates that produces the output ( p ∧ ¬ r ) V (¬ q ∧ r ). 3. (10 pts.) Prove that﹁p→(q→r) and q→(p∨r) are equal by developing a series of logical equivalences.(without using truth tables) 4. (10 pts.) Are these system specifications consistent? “The system is in multiuser state if and only if it is operating normally. If the system is operating normally, the kernel is functioning. The kernel is not functioning or the system is in interrupt mode. If the system is not in multiuser state, then it is in interrupt mode. The system is not in interrupt mode.” 5.(10 pts.) Translate these statements into English, where R(x) is “x is a rabbit” and H(x) is “x hops” and the domain consists of all animals. a) ∀x(R(x) → H(x)) b) ∀x(R(x) ∧ H(x)) 6. (10 pts.) Use a direct proof to show that the product of two odd numbers is odd. 7. (10 pts.) Use proof by contraposition to prove that if 3x + 2 is even, then x is even. 8. (10 pts.) Convert the following statements to logic, where the domain consists of all people. All your friends are perfect. At least one of your friends is perfect. 9.(10 pts.) Use rules of inference to show that the hypotheses “If it does not rain or if it is not foggy, then the sailing race will be held and the lifesaving demonstration will go on,” “If the sailing race is held, then the trophy will be awarded,” and “The trophy was not awarded” imply the conclusion “It rained.” (10 pts.) Determine the truth values of each of these statements if the domain of each variable consists of all real numbers. (a) ∃x∀y(xy = 0) (b) ∀x(x = 0 → ∃y(xy = 1))
