Answer 1

Dependent and Independent variables are regarded as variables in mathematical and statistical modeling and of course in some other aspects.

The independent variable is this case is the amount of salt.

• In this kind of scenario, one can think of independent and dependent variables in terms of cause and effect.  
• An independent variable is the variable we assume to be the cause, while a dependent variable is assumed as the effect.
