The Variance percentage indicates through the REgression equation but, the R-Square, it becoming the determination coefficient. 88.871% of the variance could be explained according to the above results.
X+y=15 0.3x+0.6y=0.4*15=6 solve the system of equation. Multiply equation one by 0.3: 0.3x+0.3y=4.5 subtract the new from the second equation: 0.3y=1.5 y=5 x=10
