Answer:
The correct selections are:
B) After the donation collection period, compare the average or total amount collected from each of the two treatment groups.
C) A placebo is not being used
F) Randomly select 500 donors to receive the literature and 500 donors to receive the phone call.
Step-by-step explanation:
What this question requires from you, is to identify the correct characteristics of the study described. Let us explain why each of the selections was made.
B) After the donation collection period, compare the average or total amount collected from each of the two treatment groups: The purpose of the study is to determine the difference in the effectiveness of two methods of fundraising. Therefore at the end of the study, the average total amount raised from each group will be compared to determine which was more effective.
C) A placebo is not being used: Placebos are sham treatments used in a control group without their knowledge. The placebos do not produce any effect similar to the results anticipated the actual treatment. Here, no group is given sham treatment, there is no "control" group given placebos hence placebos are not used.
F) Randomly select 500 donors to receive the literature and 500 donors to receive the phone call: To remove any form of bias in the study, the selection of the groups is done at random, and the number of participants in each group is the same, so as to maintain uniformity during the comparison.
C is the correct graph because u can't get a cubed root of a negative number
if u chose 8 to bring x the cubed root is 2 and 2 - 3 = -1...graph matches
Answer:
For ease of writing, θ
Step-by-step explanation:
Our angle is
To find our answers for and , we will need to use a unit circle. (I have attached the image of one).
Recall that the of an angle is equal to the y-value of the corresponding ordered pair.
And the of an angle is equal to the x-value of the corresponding ordered pair.
For the angle , the ordered pair is
This means that
