Robert is conducting an experiment on the effects of media on children. While developing the experiment, he decides that groups of selected children will be randomly assigned different durations of weekly television viewing. The participants are required to follow the specified viewing times for four weeks. A: What are the treatments in the experiment described above?

B: the different durations of weekly music listening

C: children

D: four weeks

E: the different durations of weekly computer usage

F: the different durations of weekly television viewing

bull

step-by-step explanation:

your answer is b.

x = 33.9

y = 65.6

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.

a sample of water is taken and kept in a beaker in a freezer at a constant temperature of 0°c. if the system is at dynamic equilibrium, which of these statements is true?
