Answer: The slope is 1/2 and there is no y intercept
Step-by-step explanation:
Least-squares regression is used to find the equation of best fit of a linear model
The equation of the least-squares regression line for predicting GPA from the number of absences is
The given parameters are:
The equation of the least-squares regression line is represented as:
Where:
So, we have:
Substitute values for a and b in
So, we have:
Approximate
Hence, the equation of the least-squares regression line for predicting GPA from the number of absences is

Answer:
150
Step-by-step explanation:
First a diagram which looks like a 12 sided figure where all the sides are equal.
Now draw 2 consecutive radii.
There are 12 such triangles in a 12 sided polygon.
These triangles have an apex angle of 360 / 12 = 30 degrees.
The other two angles making up the triangle are both equal. Therefore x + x + 30 = 180
2x = 150
x = 75
But 75 is 1/2 of the interior angle. There are 2 such angles making up the interior angle 75 + 75 = 150
