<span>Linear regression is a method of finding the linear equation that comes closest to fitting a collection of data points.
</span>The better the choice of line, the closer the predicted values will be to the observed values.
The differences between the data pints (observed values) and the estimated (pedicted) regression line is called the <span>residue.
</span>Residue = Observed Value -<span> Predicted Value</span>
Answer:
It looks like you wrote the equation in point-slope form perfectly!
But for part c, it seems as though x1 and y1 would represent parts of the midpoint formula. So, I would specify and say that they represent the midpoint, not just a point.
Step-by-step explanation:
Answer:
B.
Step-by-step explanation:
painting a increases expoonentially
1.05(A value)= N
same for painting b by 1.02x
but a increases .3 %more
Yes
8+3= 11
You regroup the one
4+2=6+1=7
Hope this helps!
Answer:
55
Step-by-step explanation:
3x-12=2x
+12
3x=2x +12
-2x
x=12
4(12)+ 9
48+9
=55
