For cynthia's fourth lab report, she calculated the ratio of velocities before and after the impact of a basketball bouncing on a court. this measurement is called the coefficient of restitution. she got the following four values.
0.72
0.75
0.73
0.76
the accepted value is 0.77.
cynthia's percent error was [blank]%.
enter your answer as the number that correctly fills in the blank, rounded to two decimal places, like this: 42.53

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

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.
