2 Translating English Sentences into Formulas Consider the following two predicates: S(x) : x is a student in CSE015; M(x) : x plays a musical instrument. Let the domain be the set of all people. Using the above predicates, translate the following sentences into formulas using the appropriate quantifiers and operators. a) Not every student in CSE015 plays a musical instrument. b) A person is either a student in CSE015 or plays a musical instrument, but not both. c) There exists at least one student in CSE015 who does not play a musical instrument.
1-Translate the statements using quantifiers: 1-No English majors like taking Chemistry classes 2-There is a student who is majoring in Aviation but has a roommate majoring in Literature. Sx: is a student Ax: majoring in Aviation R(x,y):y is roommate of x Lx: majoring in literature 3- every student in your class has contacted another student in your class by email or text who replied using the same method of communicating

Predicates P, T and E are defined below. The domain is the set of all positive integers. P(x) : x is even T(x, y): 2 = y E(x, y, z): x³ = z Indicate whether each logical expression is a proposition. If the expression is a proposition, then give its truth value. Logical Expression: (h) T(5, 16) → E(6, 3, 36) *Create a truth table for the expression
Check if the following statement is TRUE or FALSE. Let p(x) and g(x) be two open predicates in a universe of discourse. Is it true that (x) (p(x) v g(x)) is equivalent to (Vxp(x)) v (Vxq(x))? O True O False
Express this in predicate logic: Each email address has exactly one email box. M(x): x is an email address B(x,y): x has an email box y
. If the domain consists of all animals, express the following statements in terms of quantifiers and logical connectives, where B ( x ) = x is a bear, G ( x ) = x raids garbage cans, H ( x ) = x loves honey, and T ( x ) = lives in tents. A bear lives in a tent. Bears love honey. Only bears raid garbage cans. No bear lives in a tent. Some bears do not love honey.
TRUE OR FALSE?
Express the following statement using mathematical and logical operators, predicates and quantifiers, where the domain is the set of integers (i.e. translate into symbolic form). Then prove the statement. "If the difference of squares of two integers is even then they have the same parity" (Note: two integers have the same parity if both are even or both are odd)
Consider the sentences Vx3yP(x, y) and y\xP(x, y). Are these sentences true or false under the interpretation where x and y range over the positive integers and P(x, y) is "x divides y"? Vx³yP(x, y) is true, Vxy(x, y) is true, Vx³yP(x, y) is false, Vx³yP(x, y) is false, yvxP(x, y) is true yxP(x, y) is false y\xP(x, y) is true yvxP(x, y) is false

Exercise 1. Express the following statements symbolically using multiple quantifiers. De- fine your domains and two-variable predicates. Then negate the statements. (a) Every rational number when multiplied by some integer is an integer. Domain(s): • Predicate: • Statement: • Negation: ● Englsih translation of negation: . Which is true? The original statement or its negation? Justify your answer.
