Answer:
y = - 9.1768x2 + 122.2567x + 14.9091
Step-by-step explanation:
Given the following :
Month (x) Daily Rental Price (y) 1 $154 2 $205 3 $266 4 $358 5 $403 6 $425 7 $437 8 $430 9 $381 10 $285 11 $211 12 $195
Using the online regression equation graphing tool ; The quadratic model obtained in the form,
y = Ax^2 + Bx + C is :
y = - 9.1768x2 + 122.2567x + 14.9091
Attached below is a picture of the quadratic regression curve.
I assume that the numbers are: 4,4,6,1,5,2,6
If so, then the MAD is 1.43
To find the MAD, you first find the mean of the list. It is 4.
Then find the absolute difference of each number from the mean.
Those values are: 0,0,2,3,1,2,2
Now find the mean of those numbers and you have about: 1.43
You do 2x20 which is basically 2x2 (4) add a zero and your answer is 40
Step-by-step explanation:
I cannot give an exact result but I will try.
What it means by this is to continue the graph up to 2010.
Based on its trajectory, you would simply draw the line on.
If I made a prediction on what it would end up on in 2010, I would say 50 percent.
