obrigada wikipedia, por me proporcionar um universo tao amplo de divulgaçao cientifica.
media : ρ {\displaystyle \rho } = ( 1 n ) {\displaystyle ({\frac {1}{n}})} ∑ n = 1 N {\displaystyle \sum _{n=1}^{N}} ρ ′ {\displaystyle \rho ^{\prime }}
desvio padrao: σ = ∑ n = 1 N ( ρ ′ − ρ ¯ ) 2 n − 1 2 {\displaystyle \sigma ={\sqrt[{2}]{\frac {\sum _{n=1}^{N}(\rho ^{\prime }-{\overline {\rho }})^{2}}{n-1}}}}
score z :
z = ( ρ ′ {\displaystyle \rho ^{\prime }} - ρ {\displaystyle \rho } ) 1 σ {\displaystyle {\frac {1}{\sigma }}}
matriz:
X = ( 2 1 4 9 11 6 1 6 99 ) {\displaystyle {\begin{pmatrix}2&1&4\\9&11&6\\1&6&99\end{pmatrix}}}
cos x 2 + s e n x 2 {\displaystyle \cos x^{2}+\ senx^{2}} = 1
