open dot means < or > but not equal to.
Open dot at 4 and a line going to the left on the number line.
A dot on the number line that represents the location of the number
Only approximately. Since pi is an irrational number, it cannot be expressed numerically, but only symbolically. You can put a dot on the line very close to where pi would be, but if the scale of the line were magnified enough, there would always be some error in the placement of the dot.
a dot is the smallest point whereas a line can be assumed to be a collection of points or dots for eg- a dot is - " . " and a line (continuous dots) is " ................................. "
open dot means < or > but not equal to.
A closed dot includes the number, an open dot excludes the number. Greater than excludes the number, so it would have an open dot.
Open dot at 4 and a line going to the left on the number line.
It usually means that the line ends there but does not include that point.
It means that the number is equal to more or less of that number.
The marks you're describing represent the number 1 in a prescription. The horizontal line and dot are to help prevent reading errors.
A dot on the number line that represents the location of the number
you put a dot on the number.
A dot plot is a type of graph that shows data points along a number line. Each data point is represented by a dot above the corresponding value on the number line. Dot plots are useful for displaying the distribution of data and identifying patterns or outliers.
x = 4 is the set of all points where the x coordinate = 4 On a number line, it's easy to graph. You simply place a dot on the number 4. When you extend that number line along the y axis, the dot extends, as well, into a line.
A line which has one end, but stretches off to infinity is called a ray. If we want to show an interval such as [2,infinity) which means all the numbers between two an infinity including two, we put a close dot at two and draw a ray going to the right. Similarly for (negative infinity, 2] we draw the closed dot at 2 but this time the ray goes to the left. Now if we draw an open circle, or a the out line of a dot this mean the interval (2,infinity) where we are considering all the numbers very close to two but not two itself This is an open half line and it represents an open interval.
The dot next to your name means that you are on-line and can chat with your friends who also have g-mail. If your friends have a green dot it means they are on-line.
