Student conjecture that if x is a prime number then x plus 1 is not prime. Which of the following answer is a counterexample?
x = 2 : 2 and 3 are both primes.
What a counterexample?
a number wich disproves a proposition For example, theprime number 2 is a counterexample to the statement "All prime numbers are odd."
What is a counterexample?
a number wich disproves a proposition For example, theprime number 2 is a counterexample to the statement "All prime numbers are odd."
What is an example of a counterexample for the difference of two whole numbers is a whole number?
There is no counterexample because the set of whole numbers is closed under addition (and subtraction).
What is a conjecture about the number of factors for square numbers up to 1000?
One possible conjecture is that each square number up to 1000 has 4 factors. The conjecture is manifestly false, but it is still a conjecture.
Which counterexample shows the conjecture is falseConjecture: The square of a rational number is greater than or equal to the number.?

What number would be a counter example to the following conjecture. Prime numbers are odd?
The number 2 is even as well as prime.

There is no counterexample because the set of whole numbers is closed under addition (and subtraction).
Any number that is divisible by 3 is also divisible by 9 .Find a counterexample to show that the conjecture is false?
You are an Idiot dude. there is no such value
Any number that is divisible by 2 is also divisible by 6 Find a counterexample to show that the conjecture is false?
4 is divisible by 2 but not by 6
Is Goldbach's Conjecture true?
Perhaps. Computers have shown that it is true for some pretty large numbers, but you need to remember that there are an infinite number more out there. It hasn't been proved true yet, nor has there been a counterexample. Of course, theoretically the conjecture could be true, yet unprovable (see Godel's Incompleteness Theorem)
