What is an example of a dependent variable in math?
A dependent variable is a variable in an expression that depends on the value of another variable. For example, if y = 2x, then y depends on x. So, if x = 1, then y = 2.Differential Equation: Square Root Of 4What Is A Complex Number: Linear Programm…
Which is a good example of a dependent variable?
It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.
What are some examples of independent and dependent variables in math?
For instance, if you were to be measuring the number of miles you drove in any number of hours at a constant speed, the controlled independent variable is the time in hours and the dependent variable is the distance you drove in miles.
What is the dependent variable in math mean?
A dependent variable is a variable that represents a quantity that changes based on other quantities being manipulated in an experiment. … In the context of a function, the independent variables are the inputs to the function and the dependent variables are the outputs of the function.
What is a Dependant and independent variable in math?
key idea. There are two variables. One is called the independent variable and the other is called the dependent variable. The variable whose value does not depend on the other variable is the independent variable. The variable whose value depends on the other variable is the dependent variable.
How do you identify the dependent variable in an experiment?
The easiest way to identify which variable in your experiment is the Independent Variable (IV) and which one is the Dependent Variable (DV) is by putting both the variables in the sentence below in a way that makes sense. “The IV causes a change in the DV. It is not possible that DV could cause any change in IV.”
How do you know when a variable is dependent or independent?
Independent vs. Dependent Variables | Definition & Examples
- The independent variable is the cause. Its value is independent of other variables in your study.
- The dependent variable is the effect. Its value depends on changes in the independent variable.

How many dependent variables do you want in an experiment?
A well-designed experiment normally incorporate one or two independent variables, with every other possible factor eliminated, or controlled. There may be more than two dependent variables in any experiment.
What is a dependent variable in research?
Definitions. Dependent Variable. The variable that depends on other factors that are measured. These variables are expected to change as a result of an experimental manipulation of the independent variable or variables. It is the presumed effect.
Can time be a dependent variable?
In short, time can sometimes be treated as a dependent variable. For example, in general relativity, time will dilate near a black hole as seen by an outside observer. Thus, the outside observer could describe time as a dependent variable that depends on position (distance from the gravitating object).
Is temperature a dependent variable?
So, the temperature is dependent, and the time is independent. If you’re looking at a graph, the independent variable is generally on the horizontal axis. Also, when you’re looking at an equation, the independent variable is usually on the side that has other numbers and arithmetic.
Is height a dependent variable?
An example of a dependent variable is how tall you are at different ages. The dependent variable (height) depends on the independent variable (age).
Is money independent or dependent?
Think of the independent variable as the “cause” and the dependent variable as the “effect.” The money earned changes depending on the hours worked, so the money earned is the dependent variable.
Are hours dependent or independent?
Explanation. Independent variable is Time in hours; Dependent variable is Distance in miles.
Why is y the dependent variable?
Mentor: That’s right, y is the dependent variable because we do not set a value of y directly; instead, we set a value of x and use that to find the value of y.
Is Fxa a variable?
It is because f(x) is not a variable. In Wikipedia, the word “variable” appears out of nowhere and I could not figure out why f(x) cannot be a variable. My idea is that if we say “∀f(x)” then f(x) will be considered as a symbol without meaning rather than “value of a function f”.
What does F mean in an equation?
‘f’ is just the name of the function, ‘x’ is just the function’s input and ‘y’ is just the function’s output. So y = f(x) means: a function called ‘f’ which inputs ‘x’ and outputs ‘y’. You could even declare a function like this: function(input) = output.
What is the F in math?
more … A special relationship where each input has a single output. It is often written as “f(x)” where x is the input value. Example: f(x) = x/2 (“f of x equals x divided by 2”)
Is 7 a term?
The 5x is one term and the 7y is the second term. The two terms are separated by a plus sign. + 7 is a three termed expression.
How many terms does a Monomial have?
one term
A monomial is an algebraic expression that has only one term. The basic building block of a polynomial is a monomial. A monomial is one term and can be a number, a variable, or the product of a number and variables with an exponent. The number part of the term is called the coefficient.
Is a coefficient a constant?
When a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.
