The best method that would lead to a more effective study is:
- This experiment should be double blind. Neither the subject nor the technician should know which group is receiving the new medication and which is receiving the placebo. This method would control for the placebo effect and prevent any effect on the response.
Double blind experiments are usually better than single blind experiments because they will account for experimenter bias which is where the technicians influence the project whether knowingly or unknowingly.
The placebo effect is also better studied because the participants will not know whether they are receiving a placebo or the real thing.
In conclusion, option A is correct.

Answer:
m = 9
Step-by-step explanation:
The slope of a line can be found through rise-over-run: dividing the change in y-coordinate over the change in x-coordinate -- (y₁ - y₂) ÷ (x₁ - x₂)
That looks like this: (-2 - 7) ÷ (-7 + 6) --> subtracting negative = adding positive
Add: -9 ÷ -1
Divide: 9
Answer:
All you need to do to find factors is divide the number you want to find the factors for by a number and you can do it over and over again as long as you use the same number you want to find a factor for.
In 1 year, it erodes 2 5/18
In 8 years, it will erode: 8*2 5/18= 41/9
Answer= 41/9 = 4 5/9
