Answer:
the equation of the least-squares line for the data is: 
Step-by-step explanation:
In a simple linear regression model, such as,
, the coefficients bo and b1 are estimated through the method of least squares by the use of the equations:

For the data provided you have to:
, thus:

the equation of the least-squares line for the data is:

Hi!
The sum of all angles on a line is 180 degrees.
y = 180 - 2x
Hope this helps!
Best estimate would be to round 591.3 to 600 and round 29 to 30. 600/30 = 20.
Answer:
Part A: The two factors are 6 and 4x. Part B: Question is confusing Part C: The coefficient of the variable is 4.
Step-by-step explanation:
Factors are what gets multiplied to give a product, therefore, 6 and 4x are the products as they are both being multiplied by 5. I don't understand what you are asking for part b. Part C, the coefficient is any number that is multiplied with the variable next to in. For example, in 16x, 16 is the coefficient and x is the variable. In 9y, 9 is the coefficient and y is the variable.
Answer:
The pattern is that they are multiplying by -3 every time. 81*-3 = -243
