The result of mixing equal MASSES of water at different temperatures will be the mean of the two temperatures. Unless you are being very sophisticated and are taking the thermal expansion into account, the same will apply to volumes.
No.
Co can mean joint, together or the similar; however it doesn't always mean equal. For example: co-owners in a business are both owners. However, they do not necessarily have to have equal ownership.
If you mean in Excel, yes: you must always start a formula with an equal sign.
The geometric mean, if it exists, is always less than or equal to the arithmetic mean. The two are equal only if all the numbers are the same.
Not necessarily. Equal volumes do not always mean equal masses because different substances have different densities. Denser substances will have more mass in a given volume compared to less dense substances.
The result of mixing equal MASSES of water at different temperatures will be the mean of the two temperatures. Unless you are being very sophisticated and are taking the thermal expansion into account, the same will apply to volumes.
No. They are equal only if the distribution is symmetrical.
If by "equal" you mean "equal in length", yes, that is the same as "congruent".
No.

No, equal does not mean fair even though it may be fair.

The z score for the mean is always 0.
Any number to the power of 0 is always equal to 1
I think it means a truth can is always true. I means it's right.
