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:
Step-by-step explanation:
Given that Elijah threw a ball from a height of 4 feet. The ball reached maximum height of 16 feet after 2seconds
Let vertical component of his speed be v
When it reaches maximum height its velocity becomes 0
Hence
height reached by the ball =
When h=12(16-4) we get g=gravity =32
Hence 12 =2v-16(4)
v=38
Hence 
where h is calculated from the height of hand i.e. 4 feet
When it touches the ground h =-4
When it starts falling then distance travelled = 16 feet
Initial velocity =0 Accn due to gracity =32 feet
Using these we can write
So after 3 minutes from start the ball would reach the ground

Answer:
A. They were afraid of having another monarchy/king.
Step-by-step explanation:
This is because they were already under a rule of a cruel king from Britain and the whole reason they were creating this document was because they rebelled from monarchy and wanted to create a better government.
its just 0...
Thats all its -1+1 so it would equal zero
Think about it like this
-1+1 = 1+(-1)
and when you add a negative what are you doing? Subtracting!
so 1-1 equals...?
0
