Under what condition (or conditions) would one observe no change in the regression coefficient for some variable (e.g., b-hat Y on X1) when another variable is added to the regression equation? How is that explained?

when your predictor variables are perfectly UNcorrlated then they B coefficientes wouldn't change regardless of how many predictors are added or taken away...
