Variables are values that can change during the program once declared. Oppose to that, Constants, also values once declared, can't change their values.

What is a constant value that are not coefficients of variables to equations?
parameters
What is the term other things equal?
A number of associated variables are assumed to be constant
Why do you use control variables in a regression equation?
Say you want to study the effect of age on income. You would control for other variables that could effect income (for example gender, race etc...). What you are really doing is holding those variables constant so you can see if there actually is a relationship between age and income. Controling makes your findings more powerful and 'true'.
Which is the correct form for a linear equation?
The general form is for a linear equation in n variables is SUM aixi = b (i = 1,2,3,...,n) where xi are the variables and the ai are constant coefficients.
What is the general form of a direct-variation equation?
y = cx where x and y are the two variables and c is a constant.
What does constant mean in math?
Constant is a number with no variables. For an example, 12a, but this is a constant 12.
Are constant variables and derived variables the same?
Constant variables are constant, they do not change. Derived variables are not constant. They are determined by the other values in the equation.
Are constant variables and independent variables the same?
No they are not the same. A constant variable keeps going at a constant rate.
How do you keep control variables constant?
Dependent upon the variables, you need to take into consideration factors that can affect the outcome of the result; what will make the result vary in any way. If this, for example, entails the variable to be kept constant time, you will monitor the time and repeat it throughout the experiment. This is my understanding of constant variables; hope this helped.
What is the definition of constant term?
One that doesn't have any variables. for example 2x+7 the term Is +7
Can an experiment that has sveral variables be used to explain a theory?
Yes. A good example of which is the Ideal Gas Law. PV=nRT You have four variables and one constant.
What are constant and controlled variables?
Constant/controlled variables are variables that remain the same throughout an experiment. For example, if you wanted to see whether light affected how well plants grow, you would feed them equal amounts of water, so that the only variable affecting their growth was light exposure.
What is the constant and the variables in Boyles law?
The constant k is a...constant specific for the system considered.
What is a monomial with no variables?
constant
How many variables are kept constant in a experiment?
All variables except one, the experimental variable, are kept constant in an experiment.
What is the relation between variable and constract?
Did you mean "variables and constant"? Variables vary taking on various values whereas constants do not change and remain fixed. Temperature, number of accidents per day in a city, number of children born in a city are examples of variables. Number of planets in our solar system is an example of a constant.
What are the two types of variables?
The two types of variables are the CONSTANT and CONTROL.
