With an open circle, the number at which the circle is is NOT included in the dataset; with a closed circle it is.
For example if a line is drawn on the number line between 0.5 and 1.5 with a closed circle at 0.5 and an open circle at 1.5, then it represents the numbers between 0.5 and 1.5 including 0.5 but excluding 1.5; this range is the numbers which round to 1 to the nearest whole number.

Which do you use an open circle or closed cirle for graphing inequalities?
A closed circle is when a range of numbers also includes that number and an open circle is when a range of numbers doesn't include that number, :)
What is the difference between an open circle and a close circle on a number line?
an open circle on a number line means the answer is just less than or greater than (< or >), but a closed circle means the answer is less than or equal to, or greater than or equal to (< or > with a line under it)
Is a circle closed figure or open figure?
closed figure
How do open and closed circles relate to solid and dashed lines?
An open circle should have a dashed circumference, a closed circle a solid one.
Between 1 and 3include 1 and 3?
If you are referring to a number line: If it is between 1 and 3, then no you would not include 1 and 3... If the notation is [1,3] then 1 and 3 are included (both 1&3 would be closed circles on the # line) If the notation is (1,3) then 1 and 3 aren't included (1 & 3 would be open circles on the number line) If the notation is [1,3) 1 is included 3 is not (1 is a closed circle, 3 is an open circle on # line) If the notation is (1,3] 1 is not included, 3 is included (1 is open circle, 3 is closed circle on the # line)
