What number is z.

In mathematics, a complex number is an element of a number system that includes both real numbers and a specific element denoted by the symbol i. If |z| = 1, it is claimed that the complex number z is unimodular. If both z 1 and z 2 are complex numbers, then the unimodularity of the expression z 1 – 2z 2 / 2 – (z 1 – z 2) must contradict ...

Google Classroom What are z-scores? A z-score measures exactly how many standard deviations above or below the mean a data point is. Here's the formula for calculating a z-score: z = data point − mean standard deviation Here's the same formula written with symbols: z = x − μ σ Here are some important facts about z-scores:The symbol for the atomic number is designated with the letter Z. For example, the atomic number (z) for sodium (Na) is 11. That means that all sodium atoms have 11 protons. If you change the atomic number to 12, you are no longer dealing with sodium atoms, but magnesium atoms.
