One of the assumptions made in OLS regression is that a) the error terms are dependent
b) the model is nonlinear
c) the error terms are normally distributed
d) the error terms are all equal
e) the error terms have unequal variances

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

the answer is y = 11.54

hope this : )
