Problems on Turing Machines

In the computational world, the Turing machine is a powerful computation engine. The invention of the Turing Machine is done by Alan Turing in 1936. A Turing Machine (TM) is a diagrammatic model of a fictional computer. It determines an output from a set of input variables using a pre-defined set of rules. It is used to get around the limitations of finite automata and pushdown automata.

3. Use rules of inference to show that the hypotheses "If it does not rain or if it is not foggy,
then the sailing race will be held and the lifesaving demonstration will go on," "If the sailing
race is held, then the trophy will be awarded," and "The trophy was not awarded" imply the
conclusion "It rained."
4. For the argument below, explain which rules of inference are used for each step.
"There is someone in this class who has been to France. Everyone who goes to France visits
the Louvre. Therefore, someone in this class has visited the Louvre."

3. Use rules of inference correctly to show that the hypotheses ”If it does not rain or if it is not foggy,then the sailing race will be held and the lifesaving demonstration will go on,” “If the sailingrace is held, then the trophy will be awarded,” and “The trophy was not awarded” imply theconclusion “It rained.” PS: Please do it in a word processor and not handwritten.
Inference question in discrete mathematics. Use the example solution in the picture to solve this inference question. Given the premises: If the steak is well done, it’s overcooked. If the steak is overcooked, the fire alarm will go off. Either the batteries have been changed or the fire alarm will not go off. The batteries have only been changed if the ladder is in the room. The ladder is not in the room. Conclude that the steak is not well done. These premises don’t make sense in the real world. Why? How can you change the premises so that they make sense in the real world? (They don’t have to end up perfectly correct, but they need to avoid the obvious problems you uncover in part B.)

By using propositional variables, logical connectives, and quantifiers, determine whether the argument is valid. If it is valid, what rule of inference is being used? If it is not, what logical error occurs?
(1) Check whether the following sentence is valid (i.e. true in all possibilities) or not by using the truth-table method. If-(if-A-then-C)-then-(if-(A-and-B)-then-C).
Please refer to the attachment for the question. I know there's quite a few options, may I request in particular option (i), (iii), (v) and (viii)? The answer given to me is (i) = No, (iii) = Yes, case 1, (v) = No, (vii) = Yes, case 3 but I don't know how to differentiate whether master theorem is applicable despite having the same or similar f(n). Thank you.
Both questions please
Are the following inferences deductively valid, inductively valid, or neither? Why? José is Spanish; all Spanish people are Catholics; so José is Catholic Most apples are delicious so this apple is delicious Some Pit Bulls are vicious; Fido is a Pit Bull; so Fido is vicious Nobody has ever seen an alien, so there aren't any
Part 1: Choose two of the proofs below and use one of the indirect proof techniques (reductio ad absurdum or conditional proof) presented in Chapter 8 to demonstrate the validity of the arguments. The proofs below may use any of the rules of inference or replacement rules given in Chapter 8. 1.(G • P) → K, E → Z, ~P → ~ Z, G → (E v L), therefore, (G • ~L) → K 2.(S v T) ↔ ~E, S → (F • ~G), A → W, T → ~W, therefore, (~E • A) → ~G 3.(S v T) v (U v W), therefore, (U v T) v (S v W) 4.~Q → (L → F), Q → ~A, F → B, L, therefore, ~A v B 5.~S → (F → L), F → (L → P), therefore, ~S → (F → P) Part 2: Below are basic arguments in English. Choose two arguments and translate those argument into the symbolism of predicate logic. You do not need to do a proof. Every fetus has an immortal soul. A thing has an immortal soul only if it has a right to life. Hence, every fetus has a right to life. (Fx = x is a fetus, Sx = x has an immortal soul, Rx = x has a right to life). Some wars are just. No war of…
Please provide an answer with explanation to the attached question.
Using predicate logic, prove that the following argument is valid. Provide the translation and the proof sequence. Every computer science student works harder than somebody, and everyone who works harder than any other person gets less sleep than that person. Riley is a computer science student. Therefore, Riley gets less sleep than someone else. Use the symbols, C(x), W(x,y), S(x,y), r.
