I define an variable by saying x- an value
Declaration is a promise: 'I will define (or has defined) this variable/function somewhere else'.
int x; "Example"
Can't really say. X is a variable and untill you define that variable, it can't be answered.
Any variable can be declared as the independent variable, then the other would be the dependent variable. However, it is quite common to arbitrarily define y as the dependent variable - a variable that depends on x.
It means any thing that you define it to mean.

They define a variable by saying n equals some value.
define
yes we can define a variable in an interface in java.
I suspect that you mean that you want to define constants, which is not possible in Python. Any variable can be rebound to something else at any time.
Pointer is a variable, A variable that stores the address of another variable. Size of a pointer is 2 bytes.

Operational definition

That depends on the rules that define the random variable.
