Step-by-step explanation:
Coefficient of determination is represented by . This tells us that how much of the variation in the dependent variable is explained by the independent variable.

Hence,
Coefficient of determination =
=
= 0.89
∴ 89% of the variation in the dependent variable is explained by the independent variables.
