Independent And Dependent Variables In Math Examples
The dependent variable is the one that depends on the value of some other number.
Independent and dependent variables in math examples. The rate of miles per hour is a constant it is neither independent nor dependent. And the hours you drive is the independent variable. Example of variables in mathematics if an equation shows a relationship between x and y in which the value of y is dependent upon the value of x y is known. If say y x 3 then the value y can have depends on what the value of x is.
Analyze the relationship between the dependent and independent variables using graphs and tables and relate these to the equation. Examples of independent and dependent variables in experiments independent variable. Dependent independent variables. Number of kernels popped this is the dependent variable because it s what you measure for.
If the value of x is said to be 1 input then the value of y will be 2 output. In the function above y is the dependent variable and x is the independent variable. In a study to determine whether how long a student sleeps affects test scores the independent variable is the length of time spent sleeping while the dependent variable is the test score. So for y x 3 when you input x 2 the output is y 5.
But the hours you drive does not depend on the distance you drive. Rotation speed measured in revolutions per minute dependent variable. The dependent variable would be the flow of water measured in liters per minute. Graphing our mission is to provide a free world class education to anyone anywhere.
Independent and dependent variable examples. Electricity voltage controlled in volts independent variable. Khan academy is a 501 c 3 nonprofit organization. Another way to put it is the dependent variable is the output value and the independent variable is the input value.
You want to compare brands of paper towels to see which holds the most liquid. Brand of popcorn bag it s the independent variable because you are actually deciding the popcorn. Therefore the distance you drive is the dependent variable.
