7.75 is the mean of 6.5 and 9.
The geometric mean of 9 and 25 is: 15.0
The geometric mean of 9 and 81 is 27.0
9*9
The mean is found by adding the values together and dividing by the number of values. 5+7+9+11+13+9 = 54 54 divided by 6 is 9. The mean of 5, 7, 9, 11, 13, 9 is 9.
You cannot use deviations from the mean because (by definition) their sum is zero. Absolute deviations are one way of getting around that problem and they are used. Their main drawback is that they treat deviations linearly. That is to say, one large deviation is only twice as important as two deviations that are half as big. That model may be appropriate in some cases. But in many cases, big deviations are much more serious than that a squared (not squarred) version is more appropriate. Conveniently the squared version is also a feature of many parametric statistical distributions and so the distribution of the "sum of squares" is well studied and understood.

It depends on whether you mean 45, 4.5, 0.45, 0.045, or 0.0045 If you mean 45, the answer is 45/1 If you mean 4.5, the answer is 9/2 If you mean 0.45, the answer is 9/20 If you mean 0.045, the answer is 9/200 If you mean 0.0045, the answer is 9/2000
9 = sr, could mean "9 equals square root of 81".
Do you mean "What are the 9 alphabets?"
9*9
The mean is found by adding the values together and dividing by the number of values. 5+7+9+11+13+9 = 54 54 divided by 6 is 9. The mean of 5, 7, 9, 11, 13, 9 is 9.
If you mean 9 and 3 fourths inches, the answer is: 9 and 3/4 inches! If you do not mean 9 and 3 fourths inches you should say what units mean.
