No. It also applies to mathematics in general.
-- You select an operation. -- You apply the same operation to each side of the equation. -- You keep doing both steps until the equation says (the variable) = (the value of the variable)
A continuous variable is a variable for which all possible representations are valid. A discrete variable is a variable for which only some representations are valid. Discontinuous variables apply to data sets where values recorded during particular periods are missing from the set.
Angle J is congruent to angle K line KL is parellel to line Jm
In an experiment, the independent variable is the variable that is manipulated by the experimenter in order to observe and measure how it affects the dependent variable. For example, an experiment in which the experimenter wants to observe and measure the effect of force on the acceleration of an object, force would be the independent variable and acceleration would be the dependent variable. The experimenter would apply different amounts of force to an object, and then observe and record the object's acceleration with each amount of force. On a graph, the independent variable would be on the x-axis, and the dependent variable would be on the y-axis.
