Step-by-step explanation:
We are given the following information:
The estimate regression equation for a model involving two independent variables and 10 observations follows:

where
are the two independent variable and y is the dependent variable.
a) The regression line is of the form:

Comparing, we get,

These are the coefficients of
respectively, and helps us to know the the significance of the independent variable in predicting the independent variable.
b) We have to estimate y when

Answer:
4y+104
Step-by-step explanation:
To distribute, multiply everything inside the parentheses by the number outside the parentheses
4(1y+26)
Multiply 4 by 1y+26
(4*1y) +(4*26)
4y+104
Step-by-step explanation:
the lebgth to form the right angle is e9
