You substitute the variable for its value. Or you substitute the variables for each of the values.
In mathematics, the expression "2a" represents the product of 2 and the variable "a." This means that you are multiplying the number 2 by the value of the variable "a." The result will depend on the specific value assigned to the variable "a."
you have to deduce the variable and evaluate the expression.
You cannot plug in a variable, what you do is plug in the value for a variable. If you know the value of the variable in an equation (or formula), the process of replacing that variable whenever it appears in the equation by its value is called plugging in the value for the variable.
If you define a variable, it can have ANY value - so yes, that includes zero.In a specific problem, it may have a specific value; which may be given, or you might need to figure it out.
The definition of constant variable is a variable whose value cannot be changed once it has been assigned a value for an experiment. It is the variable held steady, or constant, for a specific experiment.
No. The probability that a continuous random variable takes a specific value is always zero.
Zero.
You substitute the variable for its value. Or you substitute the variables for each of the values.
A nominal variable is a variable measured in current dollars (the value of the dollar for the specific period discussed), and a real variable is a variable measured in constant dollars (the value of the dollar for the base period). That is, a real variable adjusts for the effects of inflation.

with an assignment: variable = value variable += value variable /= -3; ...
The dependent variable is the variable that depends on the independent variable.
You cannot plug in a variable, what you do is plug in the value for a variable. If you know the value of the variable in an equation (or formula), the process of replacing that variable whenever it appears in the equation by its value is called plugging in the value for the variable.
A constant is a variable that remains the same and does not change its value during a specific process or calculation. This allows for consistency in mathematical or scientific equations.
Generally speaking, a letter in algebra refers to a variable, that is, it is a placeholder for any specific value that can be used in that equation.In algebra syntax, a number next to a variable, or a variable next to another variable, with no explicit arithmetic symbol between them, mean to multiply the two values.So:2aMeans to multiply the variable value of "a" by two.In your question:2aball values should be multiplied. So, the result would be 2 times the variable value of "a" times the variable value of "b".
