Why do we need the quadratic mean How is it better than the average mean?

The quadratic mean is a measure of the spread of values about their arithmetic mean. By definition, the arithmetic mean of the differences will be zero and so adds no information. Another measure is required and that is the quadratic mean.

How do you calculate the average deviation?
You don't need to. Average deviation (about the mean) is always zero!
If the right-hand side of a quadratic equation does not equal zero you need to the number or expression on the righthand side from both sides before you can use the quadratic formula?
subtract
What number comes next in the sequence -1 0 1 8?
You cant solve the next term (next number) in this sequence. You need more terms, because this is either a "quadratic sequence", or a "linear and quadratic sequence", and you need more terms than this to solve a "linear and quadratic sequence" and for this particular "quadratic sequence" you would need more terms to solve nth term, which would solve what the next number is. If this is homework, check with your teacher if he wrote the wrong sum.
When do you ever need to use the quadratic formula in life?
Nearly every day on Wikianswers!
Is yx3cubed plus x2squared a quadratic inequality?
No. This is not an inequality, because you need something > something_else, or less than or 'not equal' or 'greater than or equal', etc. Since it has an x cubed term, it is not a quadratic.
What are comparisons between a cubic and quadratic function?
They are both polynomial functions. A quadratic is of order 2 while a cubic is of order 3. A cubic MUST have a real root, a quadratic need not.
How is the quadratic equation used in volleyball?
If you refer to actually playing volleyball, you certainly won't need the quadratic equation or other advanced math.
How do you calculate the average deviation?
You don't need to. Average deviation (about the mean) is always zero!
Why we need quadratic equation?
Whenever you are describing an object in motion that is accelerating or decelerating (due to gravity for example), the resulting equation will be quadratic. This is just one example.
When do you use the quadratic formula?
When you need to find the roots of a quadratic equation and factorisation does not work (or you cannot find the factors). The quadratic equation ALWAYS works. And when appropriate, it will give the imaginary roots which, judging by this question, you may not yet be ready for.
If the right-hand side of a quadratic equation does not equal zero you need to the number or expression on the righthand side from both sides before you can use the quadratic formula?

How do you find the mean if the average age is24?
The mean is a type of average. You have told us that the average age is 24. If this is the mean average then you have answered your own question. So first you need to establish whether the average you are quoting is the mean, median or mode average. If it is the mean average then you have your answer. If it is not the mean average then you can calculate this by summing all the ages and then dividing by the number of people whose ages you have just summed.
Does rehab mean need to get better?
Yes it can be a long process

Do you have any other examples of real life applications of quadratic formulas?
you need it in carpentry
How do doctors use the quadratic formula?
Doctors use them somehow which you don't need to know.
