Answer: D. minimizes the sum of the squared residuals
Step-by-step explanation: The ordinary least square method is often used in locating the trendine which best fits a graphical linear model. The best is one in which the sum of the squared residual is smallest. The residual refers to the difference between the actual and the predicted points. The sum of the squared differences is obtained and the trend line is positioned where the residual is minimum. Choosing a OLS, and minimizing the sum.of the squared residual, the error difference between the predicted and actual score is minimized or reduced, hence, improving the prediction accuracy of our model.
The number in the photo should be the answer but the problem might just be that your question was worded incorrectly.
Answer:
Observation : No two such factors can be found !! Conclusion : Trinomial can not be factored. Equation at the end of step 1 : x2 - 7x - 14 = 0. Step 2 : Parabola, Finding the Vertex: 2.1 Find the Vertex of y = x2-7x-14
EXPLANATION:
Let the no. of orders Greg served be x.
Orders Chau served = 2x
Orders Maya served= x + 9
Orders served in all= 69
x + 2x + x + 9 = 69
=> 4x + 9 = 69
=> 4x = 69 - 9
=> x = 60/4
=> x = 15
ANSWER:
Number of orders Maya served = (15 + 9) 24
Number of orders Greg served = 15
Number of orders Chau served = (2*15) 30
