We check the directory for new file:

ls (to display entire file/folder)

then move the new file to TweedleDee directory

mv ~/UnixCourse/fileAsst/'name of file' ~/UnixCourse/fileAsst/TweedleDee

we then rename the file to rabbit.dat

mv ~/UnixCourse/fileAsst/TweedleDee/'name of file' ~/UnixCourse/fileAsst/TweedleDee/rabbit.dat

cd .. (this is to go back to the fileAsst directory)

A lot of printers would work. I recommend HP printers because that is what I use and they work great for me.

One of my favorite ones is the HP Deskjet 2543. You can print in black and color, you can copy, and you can scan. Connect it to the computer with a USB port and wait for the computer to recognize it, then you are ready to go. It also supports wireless printing. You can print something from your phone without any cables. How cool is that?

Prove whether each argument is valid or invalid. First find the form of the argument by defining predicates and expressing the h
SSSSS [86.1K]

Answer:

The given argument  ∀x (S(x) ∧ (M(x) V D(x)) --> ¬ A(x)) ∧ S(Penelope) ∧ A(Penelope) -->¬ D(Penelope) is valid.

Explanation:

Solution:

Let us Consider following predicates:

M(x): x missed the class

D(x): x got a detention

S(x): x is a student in the class

A(x): x got an A

Now,

We Express the hypotheses and conclusion as:

The hypotheses: ∀x (S(x) ∧ (M(x) V D(x)) -->  A(x)) and S(Penelope) and A(Penelope)

So,

The Conclusion:  D(Penelope)

Thus,

The Argument:

∀x (S(x) ∧ (M(x) V D(x)) -->  A(x)) ∧ S(Penelope) ∧ A(Penelope) -->D(Penelope)

Then,

The given argument is valid or correct and prove using the inference  rule as follows:

Step                      Premises                    Reason (Rule used)

1.  ∀x (S(x) ∧ (M(x) V D(x)) -->  A(x))                Premise

2. S(Penelope) ∧ (M(Penelope)

  V D(Penelope)) --> ¬ A(Penelope)            Universal instantiation

3.  S(Penelope)                                              Premise

4.  A(Penelope)                                              Premise

5. ¬[S(Penelope) ∧ (M(Penelope)

  V D(Penelope))]                                         2,4, Modus Tollens

6. ¬S(Penelope) V (¬M(Penelope)

  ∧ ¬D(Penelope))                                        De Morgan law

7.¬M(Penelope) ∧ ¬D(Penelope)                 3,6,Disjunctive Syllogism

8¬D(Penelope)                                              7, Simplification

Therefore, the given argument ∀x (S(x) ∧ (M(x) V D(x)) --> ¬ A(x)) ∧ S(Penelope) ∧ A(Penelope) -->¬ D(Penelope) is valid.
