75Average — In mathematics, an average, or central tendency[1] of a data set is a measure of the middle value of the data set. Average is one form of central tendency. Not all central tendencies should be considered definitions of average. There are many… …
760.999... — In mathematics, the repeating decimal 0.999... (which may also be written as 0.9, , 0.(9), or as 0. followed by any number of 9s in the repeating decimal) denotes a real number that can be shown to be the number one. In other words, the symbols 0 …
