Let T = {1,2,3,4}. Select all the true statements. Select one or more: 0 There is an equivalence relation on T that is also a partial ordering on T. There is an equivalence relation on T with exactly 3 different equivalence classes. x Ry for all x, y E T, is an equivalence relation. x Ry iff x #y, is an equivalence relation on T.

Redundant Inequalities:prove statementLet e1, e2 be two symbolic expressions defined in V ∪P and q ∈ V ∪P.c1, c2 are two inequalities of I such that c1 is defined by e1 REL q and c2 by e2 REL q. REL is an inequality relationship in {≤, <}. Then c2 can be eliminated from I, iff low(e1 − e2) ≥ 0.
Formal Specification Predicate Logic By quantificationA quantifier is a mechanism for specifying an expression about a set of values. Thereare three quantifiers that we can use, each with its own symbol:–The universal quantifier ∀This quantifier enables a predicate to make a statement about all the elements ina particular set. For example, if M(x) is the predicate x chases mice, we could write:∀x Cats ● M(x)This reads For all the x which are members of the set Cats, x chases mice, or, moresimply, All cats chase mice.– The existential quantifier ∃In this case, a statement is made about whether or not at least one element of a setmeets a particular criterion. For example, if, as above, P(n) is the predicate n is aprime number, then we could write:∃n ● P(n)This reads There exists an n in the set of natural numbers such that n is a primenumber, or, put another way, There exists at least one prime number in the set ofnatural numbers.–The unique existential quantifier !This quantifier…

Let L be L(A), where DFA A = (Q,T, 8, q0, F) over alphabet T = {a, b}. Let h be the homomorphism defined by h(0) = aba and h(1) = €. For the DFA A shown in the figure below, define a DFA B = (Q,E, Y, q0, F) over alphabet E = {0,1}, where h-1(L) = B. Toearn a full credit, the definition for B must be both complete and correct. To solve this problem, you must answer all components for the DFA B. a В A b a h(0) = aba h(1) = €
A statement form is satisfiable if there is an assignment True/False for its variables such that the statement form is True. Otherwise, that is, if no such assignment exists, the statement form is called unsatisfiable. Consider the statement form = (p → q) ^ (~ p V r) ^ (qV ~ r) Use a possibility tree to decide if is satisfiable or not.
