Question

Use the change of quantifier rule together with the eighteen rules of inference to derive the conclusions of the following symbolized argument. Do not use either conditional proof or indirect proof.

The image displays a logical proof interface used for constructing formal proofs in symbolic logic. Here's a transcription and explanation of the components:

### Symbols and Operators:
- **Quantifiers**:
\((\exists x)\) - There exists an \(x\)
\((x)\) - For all \(x\)

- **Logical Connectives**:
• - And (conjunction)
\(\sim\) - Not (negation)
\(\supset\) - Implies (conditional)
\(\lor\) - Or (disjunction)
= - Equals
\(\neq\) - Not equal

- **Grouping Symbols**:
() - Parentheses, used for grouping
{} - Curly brackets
[] - Square brackets

### Rule Abbreviations:
- **CQ, MP, MT**: Related to conditional and quantification logic rules
- **UI, UG, EI, EG**: Universal and existential instantiation and generalization
- Others like **DN, Trans, Impl** indicate specific transformation and inference rules in logic.

### Proof Structure:
1. **Line 1:**
- **Premise:** \(\sim(\exists x)(Ax \cdot \sim Bx)\)
- This line indicates that in the premise, it is not the case that there exists an \(x\) for which \(Ax\) and not \(Bx\) both hold true.

2. **Line 2:**
- **Premise:** \(\sim(\exists x)(Ax \cdot \sim Cx)\)
- **Conclusion:** \((x)[Ax \supset (Bx \cdot Cx)]\)
- This line indicates a premise similar to line 1, but concludes that for all \(x\), \(Ax\) implies both \(Bx\) and \(Cx\).

3. **Line 3:**
- Empty, indicating space for another premise or conclusion to be added as part of the proof development.

### Interface Controls:
- **Buttons and Fields:** Allow users to add or edit premises and conclusions, apply logical inference rules, and check the correctness of the steps in the proof.

This type of interface is commonly used in educational settings for teaching formal logic, enabling students to learn and apply logical rules methodically.

Translate the following arguments in to symbols and determine which rule of inference shows the argument is valid. p: The date is June 25, 2010. q: The temperature is above 80 degrees. r: It is sunny. If the date is june 25, 2010, then the temperature is above 80 degrees. The date is June 25, 2010. The temperature is above 80 degrees.
how to prove that contrapositive of the contrapositive is the original statement?
There are fallacies associated with conditional statements. The three most common are Fallacy of the Converse, Fallacy of the Inverse, and Misuse of Hypothetical Syllogism (see link below!). Pick one of these and create an argument to show why it is incorrect.
D part only plz. Thankyou.
Use the rules of inference and the laws of propositional logic to prove that each argument is valid. Number each line of your argument and label each line of your proof "Hypothesis" or with the name of the rule of inference used at that line. If a rule of inference is used, then include the numbers of the previous lines to which the rule is applied. 비 (c) (d) D EXERCISE 1.12.2: Proving arguments are valid using rules of inference. → P→ (q^r) -q -P (p^q) →r -r 9 :-P (pvq) →r p Ar pvq -pvr -q p→q r-u par q^u Feedback?
