Answer:
the 3rd number line
Explanation:
first of all, we know That the line starts from zero.
the inequation is n>0
the circle inside should be the hallow one because it's "greater" not greater than or equal to.
n>0 means that n is greater than 0.
in the number line, ( the 3rd one) n is going away from 0. it's going greater than 0.
that is why this is the correct answer.
I hope this clarified any confusion.
