What is a variable declaration? A variable declaration is a statement that sets the name of a variable and its data type. It also provides information about where the variable should be stored in memory. This process can include initializing the variable with an initial value, although that is...
A variable is something that can be changed. In computer programming we use variables tostore information that might changeand can be used later in our program. For example, in a game a variable could be the current score of the player; we would add 1 to the variable whenever the player...
Definition:A manipulated variable is an independent variable subject to the changes of an experiment to analyze its effect on a dependent variable. Simply put, the variable is modified to assess its influence over the experiment’s overall result. ...
What is the definition of variable cost per unit?Variable costs are costs which are directly related to the changes in the quantity of output; therefore,variable costsincrease when production grows, and decline when production contracts. Common examples of variable costs in a firm areraw materials...
Example- Let us take an example of the algebraic expression 2x + 6. Here, x is a variable and can take any value. If x = 1, the value of this algebraic expression will be 2(1) + 6 i.e. 8 and if x = 2, the value of the algebraic expression changes to 10. Hence, we can...
