What is running feet?
A running or linear foot is simply a measure of distance. The measure is more commonly known simply as a foot.
Why do you square the deviations and then turn around and find the square root of the sum of the squares?
If you simply added the deviations, their sum would always be zero. The derived statistic would not add any information. Essentially, the choice was between summing the absolute values or taking the square root of the squares. The latter has some very useful statistical properties.
What is the sum of acute angle is?
The sum of one angle is simply the measure of that angle.
How do you find covariance of two variables?
The covariance between two variables is simply the average product of the values of two variables that have been expressed as deviations from their respective means. ------------------------------------------------------------------------------------------------- A worked example may be referenced at: http://math.info/Statistics/Covariance
How do you convert metres into cubic metres?
This poses a problem. How can you make a measure of distance only into a measure of mass? How can you add volume to something that does not have volume? This can simply not be done.
Do you need to know the individual masses of the samples of water and salt in order to measure the change in mass when the two samples are mixed?
No, you do not need to know the individual masses of the samples of water and salt to measure the change in mass when they are mixed. You can simply measure the mass of the mixture before and after mixing to determine the change in mass.

How do you get the length of a triangle?
Simply measure it.
What is an IQ?
An Intelligence Quotient or IQ is a measure of an individual's intelligence, derived from a test that relies heavily on logical thinking, which may also include other elements in certain variations (such as simple philosophy). Simply, the IQ score is a quotient of an individual's mental age. The vladity of the IQ test is often questioned because of it's failure to account adequately for minds that think abstractly, as well as for it's reliance on time-keeping as a measure to test the individual's intelligence.

simply units....
What is the formula of inches?
There is no formula for inches. It is simply a measure of length.
When Congress reexamined the Miranda decision in 2000 what did it decide?
Basically, that MINOR deviations/technicalities should not allow a guilty person to go free, simply because someone forgot to "dot an i or cross a t."
Why cannot the accounting rate of return be used as a reliable capital budgeting technique?
Because this computation attempts to calculate the average book value of an investment by simply averaging the initial and liquidation values.
Why cant individual particle of sugar be seen?
Simply because the individual molecules are too small to be seen without a microscope.
How do you calculate oven capacity in liters?
You simply measure its volume, in litres.
What is six segma related to MBA?
Six Sigma at many organizations simply means a measure of quality that strives for near perfection. Six Sigma is a disciplined, data-driven approach and methodology for eliminating defects (driving towards six standard deviations between the mean and the nearest specification limit) in any process -- from manufacturing to transactional and from product to service.
