(a1+a2+....+am )2
=AVERAGE(A1:A34)
n/(1/a1+1/a2+....+1/an)
"Average" as in arithmetic mean is equal to (a1 + a2 + a3 + ... + an)/n, where ai are elements of a set.
A3 is 4 times bigger than A1, so only a quarter of an A3 sheet can fit into an A1 sheet.A3 is 4 times bigger than A1, so only a quarter of an A3 sheet can fit into an A1 sheet.A3 is 4 times bigger than A1, so only a quarter of an A3 sheet can fit into an A1 sheet.A3 is 4 times bigger than A1, so only a quarter of an A3 sheet can fit into an A1 sheet.A3 is 4 times bigger than A1, so only a quarter of an A3 sheet can fit into an A1 sheet.A3 is 4 times bigger than A1, so only a quarter of an A3 sheet can fit into an A1 sheet.A3 is 4 times bigger than A1, so only a quarter of an A3 sheet can fit into an A1 sheet.A3 is 4 times bigger than A1, so only a quarter of an A3 sheet can fit into an A1 sheet.A3 is 4 times bigger than A1, so only a quarter of an A3 sheet can fit into an A1 sheet.A3 is 4 times bigger than A1, so only a quarter of an A3 sheet can fit into an A1 sheet.A3 is 4 times bigger than A1, so only a quarter of an A3 sheet can fit into an A1 sheet.
EPNS A1 is the highest grade of silver plating that the manufacturer provides. EPNS = Electroplated Nickel Silver A1 = the thickness of the silver plating which is usually 30 - 35 Microns. Highest Grade of Silver plating. The higher the grade, the longer the cutlery will last. 35 Microns of EPNS will last approximately 40years, but this depends on usage, storage and care.
EPNS stands for Electro-Plated Nickel Siver. A1 denotes the highest quality of the manufacturer (usually the thickness of the plating). Lower quallities are usually labelled A, 1 or B.

I don't think so, i have my grandmas EPNS 100 silver set, and she use to send it to be plated from time to time.
They list on ebay from 10 to 20 dollars
I think you mean RWS EPNS-A1...RWS is just the manufacturer.EPNS stands for "Electro Plated Nickel Silver". Nickel Silver (sometimes stainless steel) is the base metal onto which silver is plated. Despite its name, nickel silver contains no silver at all, but is an alloy of nickel, zinc & copper. A layer of pure silver is deposited electrolytically on the base metal to give a silver finish.A1 is just the thickness of the silver plating. It usually varies between 30 - 35 Microns. It's one of the Highest Grades of Silver plating.
*Aprox* $50-$180 Depending on what condition it is in, its age, state, and other circumstances it will vary. An average good condition one will get a $80 min. Hope this helps.
The mean of the numbers a1, a2, ..., an is equal to (a1 + a2 + ..., + an)/n. This number is used mostly as the average. It is called the arithmetic mean.
