Answer:
If r-squared for the transformation is greater than r-squared for the original regression, the transformation is successful.
Step-by-step explanation:
16) First solve like a normal equation.
3|x/9| - 1 = 2
3|x/9| = 3
|x/9| = 1
Now just separate into two equations:
x/9 = 1
x/9 = -1
So x = 9, -9
17) Solve like normal:
-4 - 2|b - 10| = -6
-2 |b - 10| = -2
|b - 10| = 1
Now just separate into two equations:
b - 10 = 1
b - 10 = -1
So then b = 11, 9
The one to the right is the hundredth place
Answer:
50
Step-by-step explanation:
68+62=130 then subract 180-130 and have 50 so x=50
4.
You can get this by taking half of the middle number and squaring it.
