The system that satisfies this requirement is described as meeting the N-1 contingency criterion (N designates the number of pieces of equipment). The N-2 and N-3 contingency refers to planning for a simultaneous loss of, respectively, 2 or 3 major units; this is sometimes done for the critical area (e.g. downtown ).
An N battery (or N cell) is a standard size of dry-cell battery. An N battery is cylindrical with electrical contacts on each end; the positive end has a bump on the top. The battery has a length of 30.2 mm (1.19 in) and a diameter of 12.0 mm (0.47 in), and is approximately three-fifths the length of a AA battery.
An N of 1 trial (N=1) is a multiple crossover clinical trial, conducted in a single patient. [1] A trial in which random allocation is used to determine the order in which an experimental and a control intervention are given to a single patient is an N of 1 randomized controlled trial.
The optimal value depends on excess kurtosis, as discussed in mean squared error: variance; for the normal distribution this is optimized by dividing by n + 1 (instead of n − 1 or n). Thirdly, Bessel's correction is only necessary when the population mean is unknown, and one is estimating both population mean and population variance from a ...
This difference between n and n − 1 degrees of freedom results in Bessel's correction for the estimation of sample variance of a population with unknown mean and unknown variance. No correction is necessary if the population mean is known.

The n-th prime gap, denoted g n or g(p n) is the difference between the (n + 1)-st and the n-th prime numbers, i.e. = +. We have g 1 = 1, g 2 = g 3 = 2, and g 4 = 4. The sequence (g n) of prime gaps has been extensively studied; however, many questions and conjectures remain unanswered. The first 60 prime gaps are:
Medigap Plan N and Plan F offer very similar benefits, but some differences and rules exist. This article will look at Medigap plans, both Plan N and Plan F coverage, and alternative options that ...
