The minus symbol is an arithmetic operator used to represent subtraction. The plus-minus symbol is used in math to represent both positive and negative results from a calculation. It also indicates the error or uncertainty in measurements.
π−. . Each pion consists of a quark and an antiquark and is therefore a meson. Pions are the lightest mesons and, more generally, the lightest hadrons. They are unstable, with the charged pions. π+. and. π−. decaying after a mean lifetime of 26.033 nanoseconds ( 2.6033 × 10−8 seconds), and the neutral pion.

The formula for calculating a z-score is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation. As the formula shows, the z-score is simply the raw score minus the population mean, divided by the population standard deviation. Figure 2. The Z-score formula in a population.
The base remains the same. As the page explains, a negative exponent just means "the multiplicative inverse of the base raised to the positive opposite of the power". So a^ (-b) = 1/ (a^b). The base, a, doesn't change. Only its place in the expression changes.
So, the next one it's going to be two minus two over 0.816, this is where I got the two from and I'm subtracting from that the sample mean right over here, times, now we're looking at this two, two minus three over 2.160 plus I'm happy there's only four pairs here, two minus two again, two minus two over 0.816 times now we're gonna have three
