What does z represent in math.
Sequences and series are most useful when there is a formula for their terms. For instance, if the formula for the terms a n of a sequence is defined as "a n = 2n + 3", then you can find the value of any term by plugging the value of n into the formula. For instance, a 8 = 2(8) + 3 = 16 + 3 = 19.In words, "a n = 2n + 3" can be read as "the n-th term is given by two-enn …
The symbol for atomic number, Z, stands for "Zahl", which means number in German. Prior to 1915, the symbol Z denoted the position of an element in the periodic table. Once there was evidence that this was also the charge of the atom, Z came to be called "Atomzahl", or atomic number.

So what we can do, we can use a z-table to say for what z-score is 70% of the distribution less than that. And then we can take that z-score and use the mean and the standard deviation to come up with an actual value. In previous examples, we started with the z-score and were looking for the percentage. This time we're looking for the percentage.In a wide sense, as argued below, the answer is no. Indeed, R(z) ℜ ( z) is not a holomorphic function since its image is the real line. In this sense, there is no formula for R(z) ℜ ( z) that does not involve z¯ z ¯, because the Cauchy–Riemann equations fail for R(z) ℜ ( z) : This was said already in the comments.2.1: Statements and Logical Operators.
