3) What is a Truth Valve?

None of the above options are correct.

Of either true (T) or false (F).

A device used to measure honesty in conversations.

An electronic device that detects lies.

A tool for filtering out fake news from social media.

A Truth Valve simply refers to the concept of determining the truthfulness of a statement, indicating whether it is true (T) or false (F). It is not a physical device but rather a way of categorizing the accuracy of information.

Explanation

4) What is the definition of an Inverse in logic?

Is the statement formed by negating the hypothesis and the conclusion.

Is the statement formed by negating only the conclusion.

Is the statement formed by negating only the hypothesis.

Is the statement formed by switching the hypothesis and conclusion.

Submit

5) What is the definition of a contrapositive statement in logic?

Is the statement formed by both exchanging and negating the hypothesis and conclusion.

A contrapositive is a statement that exchanges the hypothesis and conclusion without negating either.

A contrapositive is a statement that only negates the hypothesis of the original statement, but keeps the conclusion the same.

A contrapositive is a statement that has the exact same hypothesis and conclusion as the original statement.

In logic, a contrapositive statement is formed by both exchanging and negating the hypothesis and conclusion of the original statement. This is done to prove the original statement by showing that its contrapositive is true.

Explanation

6) What is a triangle?

A shape with four sides.

Is defined as a three-sided polygon.

A circle with three corners.

A square with equal sides.

A triangle by definition has three sides, distinct from shapes like squares or circles with different defining characteristics.

Explanation

A triangle by definition has three sides, distinct from shapes like squares or circles with different defining characteristics.

7) What is inductive reasoning?

Is the process of reasoning that only one specific case is true.

Is the process of reasoning that specific cases are true because a rule or statement is true.

Is the process of reasoning that rule or statement is true because specific cases are true.

Is the process of reasoning from general cases to specific cases.

Is the process of random guessing without evidence.

Inductive reasoning involves making generalizations based on specific observations or cases, unlike deductive reasoning which starts with a general statement and applies it to specific situations.

Explanation

Inductive reasoning involves making generalizations based on specific observations or cases, unlike deductive reasoning which starts with a general statement and applies it to specific situations.

Submit

8) What is a conjecture?

A proven fact in mathematics.

A random guess with no basis.

An assumption without any evidence.

A statement you believe to be true based on inductive reasoning is called a conjecture.

A conjecture is a statement that is believed to be true based on observation or patterns, but has not been proven with certainty.

Explanation

A conjecture is a statement that is believed to be true based on observation or patterns, but has not been proven with certainty.

Submit

9) What is a counterexample?

A counterexample can be a drawing, a statement, or a number.

A counterexample is a term used exclusively in literature analysis.

A counterexample is never related to logic or reasoning.

A counterexample is always a mathematical equation.

A counterexample is a useful tool in logic and mathematics to disprove a statement or hypothesis by providing a specific example that contradicts it. It can take various forms, including drawings, statements, or numbers, to demonstrate why the original statement is false.

Explanation

Submit

10) What is a hypothesis?

A prediction based on observation.

An educated guess that must be proven.

A conclusion drawn from an experiment.

Is the part p of a conditional statement following the word if.

A hypothesis is a statement that can be tested in an experiment. It is not a prediction, guess, or conclusion.

Explanation

A hypothesis is a statement that can be tested in an experiment. It is not a prediction, guess, or conclusion.

Submit

11) What is the negation of statement p?

Of statement p is ''not p,'' written as ~ p.

The negation of statement p is 'p,' written as p.

The negation of statement p is 'p is false,' written as p is false.

The negation of statement p is 'p is true,' written as p is true.

The correct answer 'not p' is the logical opposite of statement p, indicating that statement p is false. The other incorrect answers do not accurately represent the concept of negation in logic.

Explanation

The correct answer 'not p' is the logical opposite of statement p, indicating that statement p is false. The other incorrect answers do not accurately represent the concept of negation in logic.

Submit

12) What does it mean to converse in a logical statement?

Is the statement formed by adding a negation to the conclusion.

Is the statement formed by combining two separate statements into one.

Is the statement formed by reversing the order of the words in the statement.

Is the statement formed by exchanging the hypothesis and conclusion.

In logic, the term 'converse' refers to exchanging the hypothesis and conclusion of a statement to form a new statement. This is a common concept in logical reasoning and argumentation.

Explanation

In logic, the term 'converse' refers to exchanging the hypothesis and conclusion of a statement to form a new statement. This is a common concept in logical reasoning and argumentation.

Submit

13) Which statements are logically equivalent?

A conditional and its inverse are logically equivalent.

A conditional and its converse are logically equivalent.

A conditional and its contrapositive are logically equivalent, and so are so are the converse and inverse.

A contrapositive and its inverse are logically equivalent.

When two statements are logically equivalent, the truth values of one statement guarantees the truth value of the other statement. In this case, a conditional statement and its contrapositive share the same truth values, as well as the converse and inverse. This is a fundamental concept in logic.

Explanation

Submit

14) What is Deductive Reasoning?

Is the process of collecting data to support a hypothesis.

Is the process of following a set of rules without question.

Is the process of making educated guesses based on intuition.

Is the process of using logic to draw conclusions from the given facts, definitions, and properties.

Deductive reasoning involves drawing specific conclusions from general principles or premises.

Explanation

Deductive reasoning involves drawing specific conclusions from general principles or premises.

Submit

15) What is a quadrilateral?

A three-sided polygon.

Is a four-sided polygon.

A six-sided polygon.

A five-sided polygon.

A quadrilateral specifically refers to a polygon with four sides. It is different from polygons with three, five, or six sides.

Explanation

A quadrilateral specifically refers to a polygon with four sides. It is different from polygons with three, five, or six sides.

Submit

16) What is proof?

An assumption without evidence.

A written statement of fact.

An unproven theory.

Is an argument that uses logic, definitions, properties, and previously proven statements.

Proof is not just a written statement of fact, an assumption without evidence, or an unproven theory. It involves using logic, definitions, properties, and previously proven statements to support an argument.

Explanation

Submit

17) What is a theorem?

A scientific law that has been proven experimentally.

An educated guess based on observations.

Is any statement that you can prove.

A rule that is always true in mathematics.

A theorem is a statement that can be proven using existing knowledge or principles, unlike an educated guess. It is also more specific than a rule in mathematics and may or may not be a scientific law.
