2880 is the answer because 4 weeks in a month then times it by 15 and get 60 the 12 times 4 and get 48 and then 48 times 60 and get 2880
Answer:
A line fitted to data points that minimizes the sum of the squared residuals
Step-by-step explanation:
The principle of least square(LS) consists of determining the values of the unknown parameters that will minimize the sum of squares of errors (or residuals) where errors are defined as the differences between observed values and the corresponding values predicted or estimated by the fitted model equation.
Thus, the correct definition of least square regression line is "<em>A line fitted to data points that minimizes the sum of the squared residuals</em>"
Answer:
Step-by-step explanation:
<u>Given line</u>
(a)
<em>A steeper line has a greater slope</em>
So the line
Is 4 times steeper than the given line
(b)
<em>Vertical shift down of a function y is the function (y - 4)</em>
<u>So the required line is:</u>
Answer:
L=(4,-2)
Step-by-step explanation:Left = -2 units and down = -4 units, left is x direction and down is y direction. (x,y).
