A random variable X has $$\overline {\text{X}} $$ = 0 & $$\sigma _{\text{x}}^2$$ = 1. Form a new random variable Y = 2X + 1. The values of $$\overline {\text{Y}} $$ & $$\sigma _{\text{y}}^2$$ are: Consider a system whose input x and output y are related by the equation $$y\left( t \right) = \int\limits_{ - \infty }^\infty {x\left( {t - \tau } \right)h\left( {2\tau } \right)d\tau } $$ where h(t) is shown in the graph Which of the following four properties are possessed by the system?
