What is the central angle of a circle with a diameter of 20 inches and divided into 20 congruent sectors?
1
What do you call the point where a line on a graph changes slope?
Nothing particular. The graph of y = x2, for example, changes slope at each point on the graph.
How do you graph -6 is greater than x plus 5 as an inequality on a number graph?
The inequality -6 > x+5 can be rewritten -11 > x (by subtracting five from each side) or rather x < -11. To graph this on a number line, draw an open circle over the number -11 (if the inequality included "or equal to" the circle would be filled in). Then draw a line/arrow coming out of the circle over the number line. The line should only be drawn over the portion of the number line that makes the inequality true. For instance, choose a test point. When x is -20, the inequality is true: -20 < -11. So in this case, the arrow coming out of the open circle will point to the left, in the direction that the number line is getting smaller.
What is the set of an equation in two variables in the set of all points in a coordinate plane that represent all the solutions of the equation?
To graph the set of all the solutions to an equation in two variables, means to draw a curve on a plane, such that each solution to the equation is a point on the curve, and each point on the curve is a solution to the equation. The simplest curve is a straight line.
If a circle is divided into 360 equal parts what is the degree measure of the 360 angles?
A circle is divided into 360° and each of them is 1° ■
How does information on a circle graph represented?
Each segment of the circle graph represent a part of the whole.
How do you analysis a circle graph?
Analysis a circle graph through graphs and sociograms, Kinds of graphs, level of measurement, Each sector represents a part of the whole or circle is then split into parts,or sectors.
What is a circle graph use?
A circle graph is used for showing something divided into portions. For example, a circle graph with the title "Trash in the Atlantic Ocean" would have sections and percentages of each section with labels of each section of each type of trash in the Atlantic Ocean.
What does the center of each earthquake circle represent?
It represent the seismic wave focus centerThe center of each circle is a seismograph's location.
Why does f represent the graph of a function?
Because each vertical lines meets its graph in a unique point.
What does the radious of each circle represent?
The radius of a circle is a straight line from the centre of the circle to its circumference.
What does the radius of each circle represent in science?
The radius of a circle is the distance from the circle's centre to its circumference
What type of graph uses an X above a number line to represent each number in a set of data?
This graph is called the x graph.
How are circle line and bar graphs alike and different?
A circle graph (also called pie chart, because the different data representations look like slices of a pie) will represent the data as a portion (percentage) of the whole (a full circle). A bar graph will show absolute values of each data. Both graphs allow you to compare the different data categories to each other (which one is biggest, smallest, etc.)
Which type of graph is best suited for displaying the percentages of students in each grade level at a school?
circle graph
Each sector of a circle divided into sixths occupies what percent of the area of the whole circle?
Each section of the circle is 1 sixth of the circle, so 1/6. 1/6 = .166666... = 16.66...%
Can you display data from a circle graph on to a bar graph?
Yes you can. First, determine the percentage of the whole is represented by each slice of your circle (or pie) chart. Then make a bar for each slice that is the same percentage of the height of you bar graph. If you graph represents absolute number out of a total, the same principle applies.
