Rewrite the following statement so that negations appear only within predicates (that is, no negation is outside a quantifier or an expression involving logical connectives) ¬∀x ((∀y∃z P(x, y, z)) ⊕ (∀z∀y (R(x, y, z) ∨ S(z, y)))).

Form the negation of the following statements. Then apply De Morgan's law and/or conditional law, when applicable. Negation should appear only within predicates, i.e., no negation should be outside a quantifier or an expression involving logical connectives. Show all steps. a) Vx (P(x) A R(x)) b) Vy³z(-P(y)→→ Q(z)) c) 3x (P(x) V (VZ (R(z) →→Q(z))))
Using the predicate symbols shown and appropriate quantifiers, write each English language statement as a predicate wff. (The domain is the whole world.)

Write the following English statements using the following predicates, anyneeded logical operators, and quantifiers if needed. Assume the domain of x is all students and thedomain of y is all states in US.B(x, y): Person x has been to state y. L(x, y): Person x likes state y. a. No one has been to every state in US.d. Alice has been to every state that Bob has been to.e. There is no state that both Alice and Bob have been to.

What can youconclude about P and Q if you know the statement is true? a) Make a truth table for the statement (P ∨ Q) → (P ∧ Q). c) Make a truth table for the statement ¬P → (Q ∧ R).
Let the domain be the set of all animals. Define the following predicates: A(x) : x can add. • W(x) : x can waltz. • D(x) : x is a dog. • C(x) : x is a cat. Translate each of the following logical expressions into English. 1. Vx(D(x) → (A(x) V W(x)). 2. Ex(C(x) A ¬A(x) ^ W(x)) 3. -3x(D(x) ^ A(x)) 4. Vx((D(x) V C(x)). → W(x))

Develop a system/application in Prolog that will allow grader to: load a set of student’s grades (see samples from the Table C below) query student’s final letter grade (A, B, C, etc.) by a given student’s name. query student(s) whose grade matches to the input letter grade (e.g., A). For example, show student(s) whose final letter grade is A. There are 3 types of grades for each student—HWs, Exams, and Project, with a weight of 20%, 40% and 40%, respectively, to the 100-point final. Table A and B show how the final grades (in points and letter) are computed. Table C shows samples of students’ grades. You will define the execution instructions to answer the following questions so that grader can test out your application in Prolog: how to load your source code to Prolog runtime/compiler how to load students’ grades to Prolog runtime/compiler how to query student’s letter grade how to query student(s) whose letter grade matches to an input letter grade Please DO NOT hard code any…
Let D be a set of dogs including the particular dogs Cardie (c) and Duncan (d). Define the following predicates on D: W(x) means "dog a likes walks", T(x) means “dog æ is a terrier", R(x) means "dog x is a Rottweiler", and S(x, y) means "dog a is smaller than dog y" or equivalently “dog y is larger than dog r". Using the first five of the statements below, prove the last statement using quantifier rules. (Translate the statements into symbolic ones before you start.) • Duncan is a terrier. • All terriers are smaller than Cardie. • Cardie is smaller than some Rottweiler. • If a first dog is smaller than a second dog, and the second is smaller than a third dog, then the first dog is smaller than the third. • All dogs like walks. • There is a Rottweiler who is larger than some terrier who likes walks.
