- Q1
What is a conjecture in mathematics?
A proven theorem
A general law
A type of algorithm
An unproven hypothesis based on observations
30s - Q2
What is the primary characteristic of a conjecture?
It is a type of mathematical formula
It is a claim with evidence but no proof
It is always proven to be true
It is only valid for specific cases
30s - Q3
What is the first step in making a mathematical conjecture?
Writing a proof
Sharing the conjecture with others
Proving the conjecture
Observing patterns or regularities
30s - Q4
Which of the following is a common tool used to form a conjecture?
Deductive reasoning from axioms
The Riemann Zeta function
A formal proof
Inductive reasoning based on observed examples
30s - Q5
Which of the following best describes an example of inductive reasoning in making a conjecture?
Using a known theorem to prove the conjecture
If a pattern is true for several numbers, the conjecture suggests it holds for all numbers
Applying a formula to a single case
Deductively concluding that all even numbers are divisible by 2
30s - Q6
Which of the following best describes the role of counterexamples in conjecture-making?
They disprove the conjecture by showing it doesn’t hold in all cases
They show the conjecture is likely to be correct
They help prove the conjecture is true
They have no impact on the conjecture's validity
30s - Q7
What is inductive reasoning?
Drawing conclusions based on proven facts and rules
Drawing general conclusions based on specific observations or examples
Reaching a conclusion through deductive logic
Applying a formula to derive specific results
30s - Q8
Which of the following is an example of inductive reasoning?
Concluding that all swans are white after observing several white swans
Using a known theorem to prove a new result
Proving that 2 + 2 = 4
Deductively deriving the area of a circle from its formula
30s - Q9
Inductive reasoning often leads to conclusions that are:
Probable but not certain
Always true
Formally proven
Unverifiable
30s - Q10
Which of the following statements best describes an inductive argument?
The conclusion is true in all possible cases
The conclusion is based on patterns observed in specific examples
The conclusion logically follows from established laws or axioms
If all the premises are true, the conclusion must be true
30s - Q11
Which of the following is an example of an inductive conclusion that might be drawn from observation?
The sun will rise in the east tomorrow because it has always done so in the past
All integers are either even or odd
If x = 5, then x + 2 = 7
All prime numbers are odd
30s - Q12
Which of the following is a common method of using inductive reasoning in science?
Using a known axiom to explain natural phenomena
Forming a hypothesis after observing patterns in nature
Drawing conclusions based on a universally accepted theory
Deductively proving a hypothesis using mathematical laws
30s - Q13
Which of the following best illustrates the difference between inductive and deductive reasoning?
Inductive reasoning draws conclusions from patterns, while deductive reasoning draws conclusions from general rules
Inductive reasoning can only be used in mathematics, while deductive reasoning applies to all fields
Inductive reasoning is always faster than deductive reasoning
Inductive reasoning leads to certainty, while deductive reasoning only leads to probability
30s - Q14
If you observe that the sun rises every day, you might conclude, based on inductive reasoning, that:
The sun will stop rising soon
The sun rises only on Mondays
The sun rises every day in the past, present, and future
The sun will rise in the east tomorrow
30s - Q15
You observe that the sun rises in the east every day. Based on this pattern, you conclude that the sun will rise in the east tomorrow. What type of reasoning is this?
Abductive reasoning
Inductive reasoning
Analogical reasoning
Deductive reasoning
