Hey visitors, welcome to the Matrix...
Wikifórmulas 1:
Média:
ρ ¯ = 1 n ∑ n = 1 N ρ ′ {\displaystyle {\overline {\rho }}={\frac {1}{n}}\sum _{n=1}^{N}\rho ^{\prime }}
Desvio Padrão:
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 ′ − ρ ¯ ) σ {\displaystyle z={\frac {(\rho ^{\prime }-{\overline {\rho }})}{\sigma }}}
Matriz:
x = ( 28 28 28 28 28 28 28 28 28 ) {\displaystyle x={\begin{pmatrix}28&28&28\\28&28&28\\28&28&28\end{pmatrix}}}
Relação Fundamental da Trigonometria:
cos 2 x + s e n 2 x = 1 {\displaystyle \cos ^{2}x+\ sen^{2}x=1}
This is the end...
