There are many possible situations. For example, when the data are symmetric about some fixed value of the explanatory variable.
The standard deviation is a measure of how much variation there is in a data set. It can be zero only if all the values are exactly the same - no variation.
No, direct variation is "y=ax." In direct variation a equals any real constant, b=1, and c must equal zero. If any of thee conditions are changed, it is not direct variation.
Line joining the points of equal variation is known as Iogonic line andthe line joining the points of zero variation is know as Agonic line.
Brahmagupta
Yes it is. If all the observations have the same non-zero value then the coefficient of variation will be zero.
Yes, if there is no variation: all the data have to have the same value and that value must be non-zero.
Zero is equal to zero
A standard deviation of 0 implies all of the observations are equal. That is, there is no variation in the data.
Instrumental drift is the systematic time variation of the instrumental zero value. (A small) temporal variation of the zero reading of the gravimeter.
Any number to the power zero is equal to 1 - except zero to the power zero, which is undefined. So, if x is not equal to zero, the answer is 1.Any number to the power zero is equal to 1 - except zero to the power zero, which is undefined. So, if x is not equal to zero, the answer is 1.Any number to the power zero is equal to 1 - except zero to the power zero, which is undefined. So, if x is not equal to zero, the answer is 1.Any number to the power zero is equal to 1 - except zero to the power zero, which is undefined. So, if x is not equal to zero, the answer is 1.
Any number multiplied by zero is equal to zero, including zero. Therefore, zero times zero is equal to zero. 0 x 0 = 0
Yes most of them do equal zero.
