How is testing a conjecture like finding a stament true or false?
Testing a conjecture is similar to determining the truth value of a statement because both involve evaluating evidence to establish validity. In mathematics, a conjecture is an unproven assertion that requires either proof or a counterexample. When testing a conjecture, one seeks to demonstrate it as true by finding cases that support it or to disprove it by identifying a single counterexample. Thus, both processes rely on logical reasoning and empirical investigation to confirm or refute claims.
What is the definition of the word establish?
* set up or found; "She set up a literacy program" * set up or lay the groundwork for; "establish a new department" * prove: establish the validity of something, as by an example, explanation or experiment; "The experiment demonstrated the instability of the compound"; "The mathematician showed the validity of the conjecture" * lay down: institute, enact, or establish; "make laws" * bring about; "The trompe l'oeil-illusion establishes depth" * install: place; "Her manager had set her up at the Ritz" * build: build or establish something abstract; "build a reputation" * use as a basis for; found on; "base a claim on some observation"
How do you determine if a conjecture is valid by the law of syllogism?
To determine if a conjecture is valid using the law of syllogism, you need to identify two conditional statements where the conclusion of one statement matches the hypothesis of the other. If you have statements in the form "If P, then Q" and "If Q, then R," you can conclude that "If P, then R" is also true. This logical reasoning helps establish the validity of the conjecture based on the relationships between the statements. Always ensure that the conditions are met for the syllogism to hold true.

How do you use the ideas of counterexamples to verify valid conjectures and refute invalid conjectures?
Counterexamples are used to test the validity of conjectures by providing a specific instance where a conjecture fails. If a counterexample is found, it refutes the conjecture, demonstrating that it is invalid. Conversely, if no counterexamples can be found despite thorough testing, it supports the conjecture's validity, although this does not prove it universally true. Thus, while counterexamples are critical for refutation, their absence strengthens the case for a conjecture, though further proof may still be needed for confirmation.
What is the defenesion of conjecture?
A conjecture is an unproven statement or proposition that is based on observations or patterns. It is often used in mathematics and science to suggest a possible truth that has not yet been formally established. Conjectures can serve as a starting point for further investigation and experimentation to determine their validity.
What is the future tense of conjecture?
The future tense of "conjecture" is "will conjecture."
How can you prove a conjecture false?
The word "conjecture" can be taken a number of ways. If the "conjecture" involves an inference based on false or defective information, you need only show convincing or conclusive evidence that the information is false or faulty. If the "conjecture" is the result of surmise or guessing, then it is nothing more than a guess itself, and, therefore, has no basis in fact or logic. If the "conjecture" is an unproven mathematical hypothesis, you will need to disprove its validity from its basis. Start with the basic crux of the problem and work step by step until you disprove (or prove) the hypothesis to be untrue (or true). Make sure you have good arguments and sound mathematics.

Is validity consistent?
Validity is not inherently consistent; it can vary depending on the context and specific application. For example, a test may be valid for measuring one construct but not for another. Additionally, factors such as changes in the population or conditions under which a test is administered can affect its validity over time. Therefore, it's essential to regularly assess and establish the validity of measures in their intended context.
Why is it important to establish a cause and effect between the selected known variable and unknown variables?
To show the highest degree of validity of a hypothesis.
