Determine if the following statement is "true" or "false". (a) The mathematical sentence “x+5<10” is a proposition. (b) A conjunction is false if one of the propositions is false. (c) A mathematical sentence can either be true or false, or sometimes true/sometimes false. (d) The converse of the statement “If today is Wednesday, then I have a test today.” is “If today is not Wednesday, then I have no test today.” (e) A tessellation is a rough or fragmented geometric shape that can be split into parts, each of which is a reduced-size copy of the whole.

I plugged x=1 through x=7 all of them was false. Let P(x) be the statement "(x 21)". If the domain consists of the integers, what is the truth value of ax:P(x)? "A" is the conjunction notation. O True O False 6 or 7 why they pick these value? Let P(x) be the statement "(x 21)". If the domain consists of the integers, what is the truth value of vx:P(x)? "v" is the disjunction notation. O True O False help me with this one. thanks.

Which of the following is the propositional form of the statement "If the music is sorrowful, then either Miyazono does not play violin or Arima plays piano". A S=- (M VA) B S--(MAA) (s= -M) VA D S (-MVA)
A student club holds a meeting. The predicate M(x) denotes whether person x came to the meeting on time. The predicate O(x) refers to whether person x is an officer of the club. The predicate D(x) indicates whether person x has paid his or her club dues. The domain is the set of all members of the club. The names of the members and their truth values for each of the predicates is given in the following table. Indicate whether each expression is true or false. If a universal statement is not true, give a counterexample. If an existential statement is true, give an example. Name M(x) O(x) D(X) Hillary T F Bernie F F Donald F F Jeb F Carly F F Ex (M(x) A D(x)
Let P(x) be the predicate “x > 1/x.”a) Write P(2), P( 1/2 ), P(−1), P(−1/2 ), and P(−8), and indicate which of these statements aretrue and which are false.b) Find the truth set of P(x) if the domain of x is R, the set of all real numbers.c) If the domain is the set R+ of all positive real numbers, what is the truth set of P(x)?
1) Determine the truth value of each proposition. Justify your answers. (a) 3x E R such that x³ + 3 = 0. (b) 3x EC such that x³ + 3 = 0. (c) 3! x E R such that x³ + 3 = 0. (d) 3! x E C such that x³ + 3 = 0.
