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)

Ivahew [28]

Step-by-step explanation:

0.08*300 + 0.13x = 51.95

Multiply thru by 100 to get:

8*300 + 13x = 5195

13x = 5195-2400

13x = 2,795

x = 215 hours

Leah loves chicken wings and is comparing the deals at three different restaurants. Buffalo Bills has 88 wings for \$7$7. Buffal
Ksivusya [100]

Answer:

Buffalo mild wings offers the lowest price per wing ($0.83).

Step-by-step explanation:  

Let us find unit price per buffalo wing of each restaurant.

\text{Unit rate for buffalo bills}=\frac{\$7}{8\text{ wings}}

\text{Unit rate for buffalo bills}=\frac{\$0.875}{\text{ wing}}

Upon rounding our answer to nearest cent we will get,

\text{Unit rate for buffalo bills}=\frac{\$0.88}{\text{ wing}}

Therefore, buffalo bills offers each wing for $0.88.

\text{Unit rate for buffalo mild wings}=\frac{\$10}{12\text{ wings}}

\text{Unit rate for buffalo mild wings}=\frac{\$0.83333}{\text{ wing}}

Upon rounding our answer to nearest cent we will get,  

\text{Unit rate for buffalo mild wings}=\frac{\$0.83}{\text{ wing}}

Therefore, buffalo mild wings offers each wing for $0.83.

\text{Unit rate for wingers}=\frac{\$17}{20\text{ wings}}

\text{Unit rate for wingers}=\frac{\$0.85}{\text{ wing}}

Therefore, wingers offers each wing for $0.85.

We can see that buffalo mild wings offers the lowest price per wing that is $0.83 per wing.
