pairing all players and you will have 8 pair of players facing to each other for the first round, then you will have 4 pairs of winners for the second round. after that you will have the last 4 winning players in the semifinal to go for the final match. it's like a form of a pyramid facing side way to the right. do you have seeded players? player considered as seeded 1 to be put as the first name (pair # 1), seeded 2 as the last name (in pair # 8 in your case). seeded 3 in pair # 4, and seeded 4 in pair # 5. if you would i could send you a sample sheet to your email.

4 is the answer. Here's how:\n4 appears after a break of two numbers, so the number that follows 40 must be 4

I have coached highschool and college tennis, they way most programs work is that you can only challenge two ranking spots above you.  So the most any player could move is two spots.  The way a ladder is established is through round robin play.  That means players are divided into groups according to ability and the members of that group play each other to establish an order.  There are different rules which govern how far a player falls after losing a match.  Some teams have the two players switch positions like player 3 goes to 1 and player 1 goes to 3.  Other programs have player 3 go to one but player 1 goes to two and player 2 is pushed down to the third spot.  These are the most common ways to establish a team ladder or ranking.

I play competition tennis in New York, USA. We play a team format in which we have 6 singles players who each play best of 3 sets (each set to 6, win by 2, ad scoring), and we also have three doubles teams (same as singles). After these matches finish, we usually continue by mixing up players and playing some Canadian doubles as well as other exhibition style matches.

23\n\n0 can be scored by not hitting the board(it could also be argued that 0 is not a true number). 1-20 are regular numbers. 21 is treble 7, 22 is double 11. 23 is the first prime number and can only be divided by itself and 1. therefore not available on a dartboard. \n\nGood lord - dont I sound brainy!!

These numbers seem to be defined as : x,x+2,x+3 for every triplet. \nTherefore, 1,3,4,5,7,8,9,11,12,13,15,16,...

It's number 15.\n\nBy definition, a composite number is a positive integer  which is not prime (i.e., which has factors other than 1 and itself). \n\nTherefore, the first few composite numbers (sometimes called "composites" for short) are 4, 6, 8, 9, 10, 12, 14, 15, 16, ... They're the numbers with factors other than one and itself. \n\n2, 3, 5, 7, 11, 13, ... are not included in the set because their factors are limited to only the number 1 and theirselves. That's why they are prime numbers.\n\nNote that by strict interpretation, it's impossible to determine the highest composite numbers since there are an infinite number of composite numbers. I just started from the smallest composite number and counted eight slots upwards.\n\nAlso note that the number 1 is a special case which is considered to be neither composite nor prime. That's why I haven't included 1 in the 8th.

An extract from Wikipedia\n\nAs simple as this scoring appears, the running score of each game is described in a manner peculiar to tennis: scores of zero to three points are described as "love" (or "zero"), "fifteen", "thirty", and "forty", respectively. The origin of this scoring comes from the (quarterly) stations of the clock, where "forty" was, presumably, easier to say than "forty-five." When stating the score, the server's score is stated first. If the server announces the score as "thirty-love," for example, it means that the server has won two points and the receiver none.

Most of them got it right.\n\nThis is another way to think about the result.\n\nFirst player = T or H doesn't matter\n\nSecond Player = Must be that same as the First Player\n                        =  only 2 possibility (H or T)\n                        = 1/2\nThird Player = Must be the same as First Player\n                    = again, only 2 possibility ( H or T )\n                    = 1/2\n\nIn order for the Second Player and Third Player to have the same result as First Plaer = 1/2 x 1/2\n                                 = 1/4.
