A researcher tries to find a relationship between the weight and age of teenagers. He finds from his observations that correlation between weight and age of teenagers is 0.8. He later finds that the weighing machine was broken and it always shows a weight 5 pounds more than the actual weight. What can we say about the correlation coefficient from this information?

first one because it can't have a fraction in it

step-by-step explanation:

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.
