Sure. If some of the items on the list are positive and some are
negative, then their average can be positive, negative, or zero.
But if all of them are positive, then their average must be more
than zero. Remember that the average is always greater than the
least item on the list, and less than the greatest one.
size zero in the UK is an average of size 4
Yes it can be.
Because the average deviation will always be zero.
You don't need to. Average deviation (about the mean) is always zero!
On average, approximately zero.
in circular motion
Since speed is a scalar quantity, the only way the average speed can be zero is if the instantaneous speed is at all times zero, making it not a moving body, so no on the average speed. The average velocity, on the other hand, can easily be zero. The simplest example is you running in a circle.
No. If the speed is always zero, then the average of its speed at any two points in time is also zero.
why average product labour never gets to zero
No.
An object moving in a circular path at constant speed will have a non-zero average speed and zero average velocity since velocity is a vector parameter,
You will include zero in finding an average if it is present in the problem. For example, you want to average quiz scores of 75, 100, 90, 0, 80. You would include zero. If zero isn't listed, don't use it.
No, it can't. Average VELOCITY can be zero, though.
The shed is of zero mass and zero weight
The gas molecules are in motion but if the total gas volume is stationary (Eg. closed in a container) the average gas velocity is zero. And since the square of any number is never negative. And not all molecules have zero velocity at a time. Therefore, since not all numbers are zero and no number is negative the the average of numbers should be a positive number and will not be zero.
Empty cells are ignored completely when calculating an average in Excel. If a cell contains a zero, then it is included in the calculation of the average because zero is a number and it is relevant to include it. If you want to exclude zero values in the calculation, then you could use the AVERAGEIF and set it to only include values that are above zero.
The average is zero.
