Answer:
The equation of the regression line is:
Step-by-step explanation:
The Least Squares Regression Line is the line that makes the vertical distance from the data points to the regression line as small as possible. It’s called a “least squares” because the best line of fit is one that minimizes the variance.
We have the following data:
To find the line of best fit for the points:
Step 1: Find and as it was done in the table
Step 2: Find the sum of every column:
Step 3: Use the following equations to find a and b:
Step 4: Assemble the equation of a line
The graph of the regression line is:
Answer:
I believe it's 60 legs.
Step-by-step explanation:
Each farmer has 2 legs so 2x6=12
Each cat has 4 legs so 4x6=24
Each kitten has 4 legs so 4x6=24
When you add all the sums up, you get 60.
Determinant = b² - 4ac = (-10)² + 4*1*25 = 100 - 100 = 0
So it has 1 solution.
Answer is D
Answer:
6.5
Step-by-step explanation:
43.50-24=19.5
19.5/3=6.5
Answer:
a
Step-by-step explanation:
g(x)=-x²
f(x)=|x+2|
f(3)=|3+2|=5
(g*f)(3)=g(f(3))=g(5)=-5²=-25
