A cell phone company is interested in the relationship between the number of texts per minute for their customers and customer age. Based on the collected data, the least-squares regression line is ý = 3.27 +2.14x, where x is the number of years by which age
exceeds 12. Which of the following statements best describes the meaning of the slope of the least-squares regression line?
For each increase in age of 1 year, the estimated number of texts per minute increases by 3.27
For each increase in age of 1 year, the estimated number of texts per minute increases by 2.14.
For each increase of one text per minute, there is an estimated increase in age of 327 years.
For each increase of one text per minute, there is an estimated increase in age of 2 14 years.
The slope has no meaning because the units of measure for x and y are not the same

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
