8. Given the following probabilities, find z1: (a) P(Z < z1) = 0.025
(b) P(Z > z1) = 0.025
(c) P(−z1 < Z < z1) = 0.95

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

maya’s expression will generate the wrong sum because she violated the commutative property.

step-by-step explanation:

27 +27 or 27times 2=54

the diffrence is 0

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.
