### Are there an infinite amount of multiples of 11 with an odd digit sum?

Are there infinitely many multiples of 11 with an odd digit sum?Yes.One proof [I'm not sure that this is the simplest proof for this, but it is a proof]:--------------------------Note that 209 is divisible by 11 and has an odd digit sum (11). Now consider the number 11000*10i+209. Because 11000 is divisible by 11 and 209 is divisible by 11,11000*10i+209 is divisible by 11 for all whole number values of i (of which there are infinitely many).Further, the digit sum for 11000*10i+209 is odd for all whole number values of i because the hundreds, tens and ones places will always be 2, 0, and 9 respectively, and the other digits will be either all zeros (for i=0) or two ones followed by zeros, down to and including the thousands places. Thus, the digit sum of 11000*10i+209 is 11 for i=0 and 13 for all other whole numbers i.Thus, we have have the following set of numbers (of which there are infinitely many) which are multiples of 11 and which have an odd digit sum:20911209110209110020911000209110000209...----------------[Note there are other multiples of 11 that have an odd digit sum (e.g., 319, 11319, 110319, ...).]___________________________________________________________Late addition:Here is the simplest proof:Prove that x+2=3 implies that x=1.proof:FIRST, assume the hypothesis, that x+2=3.

There are far too many Taekwondo dojang (clubs/schools) in the world to number them all. Many are with different organizations, and some are independent of any established or recognized associations, so there is no universal count. It would be safe to say they number well into the tens of thousands.

### What is the average of 209 317 243 288 190?

To find the mean of the numbers, add all the numbers and divide by how many numbers are in the list: 190 + 209 +243 + 288 + 317 = 1247 1247 divided by 5 = 249.4 To find the median, list the numbers from smallest to largest. The median is the number in the middle: 243 The mode is the number that is repeated more than any other. This list of numbers has no mode.
