<h2>D. If subjects knew they were receiving an active treatment, researchers would not have known if any improvement was due to the new medication or to the expectation of <u>feeling </u>better. If the researchers knew which subjects received which treatments, they might have treated one group of subjects differently from the other group.</h2><h2 />
For your question... the answer would be D
This is my interpretation of the questions answer. If you are thinking of a design ten just make a snake one. Its simple but not hard.
Three days
1 1/4 = 5/4
1/2= 2/4
2/4+1/4= 3/4 the first day
5/4-3/4= 2/4
2/4 = 1/4 and 1/4 = two days
the first day+ two days= 3 days
Answer:
Step-by-step Solution:
<u>Isolate the variable x to get the answer.</u>
- x − 2/5 = −1
- => x = -1 + 2/5
- => x = -1 + 0.4
- => x = -0.6
Hence, the value of x is -0.6.
Start by writing what is said:
2x + 4 = -6
From there just solve for x:
Subtract 4 from both sides
2x + 4 - 4 = -6 - 4
2x = -10
Divide by 2 to get x by itself
2x/2 = -10/2
x = -5
