Variables measured in monetary units
It is not continuous.
Yes, if you have two limiting variables with other possibles variables between them, the variables between the limiting variables would be continuous.
Not continuous => Discrete variable. Continuous => Continuous variable.
You age, your height, your mass, the speed at which you run, the energy you burn in doing so. They may be measured as discrete quantities but the underlying variables are all continuous.

Nominal and ordinal variables are both qualitative or discrete variables. Nominal variables allow for only qualitative classification while an ordinal variable is a nominal variable, but its different states are ordered in a meaningful sequence.
Nominal Variables
It is not continuous.
The difference between continuous and discrete system lies in the variables. Whereas the continuous systems have dynamic variables, the discrete system have static variables.
Yes, if you have two limiting variables with other possibles variables between them, the variables between the limiting variables would be continuous.
Not continuous => Discrete variable. Continuous => Continuous variable.
Peak power is the highest rated output of the speaker when loud (or peak) parts hit. Continuous/nominal power is the average output at normal and continuous listening levels. If you have the Peak Power rating, you can figure out the nominal level by multiplying the peak power by the square root of two (0.707). Peak Power * 0.707 = Nominal Power.
There are many ways of categorising variables. One classification, used in statistics, is Nominal, Ordinal and Interval.
nominal and ordinal is wrong; those are the two types of qualitative variables. Ratio and interval are the two types of quantitative variables.
You age, your height, your mass, the speed at which you run, the energy you burn in doing so. They may be measured as discrete quantities but the underlying variables are all continuous.
