12 salesmen at a car dealership sale 876 cars in a year The sum of square for the number of cars sold is 64716.find the mean and standard deviation of the number of sold cars

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24

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.
