Whatever the variable was.
the variable = 3
It appears that the question is incomplete and so cannot be answered. There should be a number (or variable) after "minus".
Yes. For example, consider rolling a die twice, with the random variable defined as the first outcome minus the second.
2m^2 - 8 -First you should factor out a two. --> 2(m^2-4) -You now have something squared minus something else squared; You have m squared minus 2 squared. Whenever you have something squared minus something squared as you do in this case, there is a simple rule to remember: You can reduce that expression into the quantity of the square root of the first number or variable plus the square root of the second number or variable Times the quantity of the square root of the first number or variable minus the second number or variable squared. --> In the case of your expression: ----> 2(m+2)(m-2)<-----
Your variable (a number) X, minus 100. X - 100
Use a character variable. For example: plus = '+' minus = '-' You can now refer to these symbols using the variable names "plus" or "minus".
In the expression 5-4t it is t that is the variable
It depends on what variable the probability ratio was for! The random variable could have been the number of heads minus the number of tails, for example.
x(x + 1)(x -1)
It is the Standard normal variable.
