Question

What is a conjecture? 1) postulate
2) educated guess
3) theorem
4) solution

Answer 1

A conjecture is a proposition that is not proven yet, but appears to be right and has not been disproven yet either, which is why I would say, it is an educated guess.

Answer 2

Use the following to determine the distance A (13,7) B (-9,4). 1) 5
2) √493
3) √137
4) √112

Answer 3

distance = sqrt ( (x-x1)^2 + (y-y1)^2 )
