(d) Determine if the compound proposition is a tautology, contradiction or a contingency ( -1 (p + q) + np. Clearly justify your answer.
If p and q are statement variables. T is a tautology and c a contradiction. Applying properties simply statements 1 )~(pvq) 2) ~(~p) 3) P^(~pvq)
Prove using contradiction .. That is P(x) -> ~Q(x) ... For all m and n, if mn is even,then m is even or n is even. Must use the form: 1. Assume P(x) /\ ~Q(x) 2. Definition of P(x) and ~Q(x) 3. Manipulate until you can get a contradiction. This is a tricky one.. good luck.
a. Define what it means for two logical statements to be equivalent b. If P and Q are two statements, show that the statement ( P) л (PvQ) is equivalent to the statement Q^ P c. Write the converse and the contrapositive of the statement "If you earn an A in Math 52, then you understand modular arithmetic and you understand equivalence relations." Which of these d. Write the negation of the following statement in a way that changes the...

Need help with part (C). show the equivalence using cases. Case 1: p>=q. Case 2:q>p. Thank you. 7.70 In this section, we provided the rule of thumb that the normal approximation to the binomial distribution is adequate if p +3 pg/n lies in the interval (0, 1)—that is, if 0 < p – 31pq/n and p+31pq/n < 1. a Show that p +37pqn<l if and only if n > 9(p/9). b Show that 0 <p – 31pq/n if and only...

Problem 10.13. Recal that a polynomial p over R is an expression of the form p(x) an"+an--+..+ar +ao where each aj E R and n E N. The largest integer j such that a/ 0 is the degree of p. We define the degree of the constant polynomial p0 to be -. (A polynomial over R defines a function p : R R.) (a) Define a relation on the set of polynomials by p if and only if p(0) (0)...
