Its job in the formula

Approximately equal to; the equality is not exact.

The passage around this formula

State the sample size the claim actually requires. If a system is being represented as safe at a given tail probability, report the number of trials run and compare it explicitly against the n ≈\approx k/qτq_\tau threshold needed to have observed the claimed rate with any precision, rather than letting a comfortable-sounding trial count stand in for a rate that would in fact require orders of magnitude more observations.

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
