You substitute the variable for its value. Or you substitute the variables for each of the values.
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.
dependent variable
No. The probability that a continuous random variable takes a specific value is always zero.
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.
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.
you have to deduce the variable and evaluate the expression.
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.
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".
what is a variable expression that has a decreasing value as the value of thevariable increases?
A discontinuous variable is a variable that has distinct categories. Blood type is a good example. You could be A, B, AB or O. This contrasts with a continuous variable such as height or weight, where there are an almost infinite number of possible values. Data for discontinuous variables is usually represented using a bar graph or pie chart, but never a scatter graph.
