how do you calculate from the selection below? Please explaine.

A survey conducted by a research team was to investigate how education level, tenure in current employment, and age are related to annual income. A sample of 20 employees is selected, and the data are given below. Determine the estimated multiple linear regression equation that can be used to predict the annual income given the number of years of school completed (Education), length of tenure in current employment, and age. income =143481+10011.9 educations 2193.88 *tenure +2689.24 age income =143481+10011.9 educations +2193.88 *tenure +2689.24 age income =143481+10011.9 educations 2193.88 *tenure +2689.24 age
