The coefficient of determination is 0.65.
According to the given question.
For a regression analysis,
SST = 120
and, SSE = 42
Since, coefficient of determination for a regression analysis = SSR/SST
So,
SSR = SST - SSE
⇒ SSR = 120 - 42
⇒ SSR = 78
Therefore, the coefficient of determination for the given regression analysis
= 78/120
= 0.65
Hence, the coefficient of determination is 0.65.

Answer:
y=3x-1 = x=1/3
Step-by-step explanation:
y=3x-1
to find the 0-intercept at x, underline y = 0
0=3x-1
move the variable to the left side and change its sign
-3x=-1
divide both sides of the equation by -3
x=1/3
