Doss [256]

Answer: The coefficient of determination = 0.6291

Step-by-step explanation:

Given: Total variation is 24.488, the explained variation is 15.405, and the unexplained variation is 9.083.

The coefficient of determination is computed as:

\text{ coefficient of determination} =\frac{\text{explained variation }}{\text{total variation}}

Substituting given values, we get

\text{coefficient of determination} =\frac{15.405}{24.488}

=0.6291

Therefore, the coefficient of determination = 0.6291

A line is parallel to the line y = -x + 5 and passes through the point (4. - 1). Which of the following is an equation of the
MariettaO [177]

Answer:

y = -x + 3; could also be y + 1 = -(x - 4)  or  y = -(x - 4) - 1  or x + y = 3

Step-by-step explanation:

No options given, so I hope this helps.

1. Identify any of the equations that have the same slope as your given equation (-1). If there's only one, stop here.

2. Find the y-intercept by replacing (x,y)=(4,-1) in the equation y = -x + b and solve for b: -1 = -(4) + b  ==> 3 = b

3. Replace b in the equation y = -x + b with 3.
