<h3>Answer:  C) n - 10</h3>

============================================

Explanation:

Consider an example of saying "10 less than 50" would mean we compute 50-10 = 40

Another example would be "10 less than 78" so we say 78-10 = 68

In general, we would use algebra to go from "10 less than a number" to "a number - 10" to n - 10

Whatever n is, we subtract 10 from it to get that expression.

From there, we replace n with various numbers. Eg: replace n with 50

n-10 = 50-10 = 40

-----------------

Be careful not to mix up "10 less than a number" with "10 <u>is</u> less than a number". The "is" being the difference. This single word will change what the symbol interpretation will be.

"10 is less than a number" translates to 10 < n

Missing Part of Question

Explain which rules of inference are used in the above

Answer:

Universal instantiation, Modus ponens and Existential generalization

Step-by-step explanation:

Splitting the Statement into two, we have

"Doug knows how to write program is Java"

and

"Doug can get a high paying job"

Represent Doug with x. Then the statements is rewritten as

P(x) = "x knows how to write program is Java"

and

Q(x) = "x can get a high paying job"

In logic, A premise is a statement in an argument that provides reason or support for the conclusion.

So, Statement 1 can be written as

1. P(x) ---- Premise

Then, we have

2. Vx(P(x) --> Q(x)) -- Premise. This mean that P(x) for all values in the domain.

The universal instantiation of (2) leads to

3. P(Doug) --> Q(Doug)

The modus ponens of the above gives

4. Q(Doug)

The existential generalisation from above gives

5. ƎxQ(x)

Which means someone in this class can get a high paying job.

PS:

Universal Instantiation is a valid rule of inference from a truth about each member of a class of individuals to the truth about a particular individual of that class; it is represented by VxP(x).

Existential Generalisation is a valid rule of inference that allows one to move from a specific statement, or one instance, to a quantified generalized statement, or existential proposition.

It is represented as ƎxP(x)
