The following examples are different types of variables. which are continous variables?

Any variable that can have an infinite number of possible values will be considered continuous.

That is so true, i can’t believe how true this is

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
