Complete question is;
Determine whether the experiment is blind or double blind.
Is the aspirin produced by the World’s Best Pharmaceutical Company better than that of a competitor at relieving headaches? 200 headache sufferers are chosen at random. Migrained Testing Service administers the experiment and provides the results evaluation. Three levels are made: participants receive contents from Bottle A, Bottle B, or Bottle C. Other than the fact that one bottle contains placebo aspirin, no other information is given to the testing service regarding the bottles’ contents.
a) blind study
b) double blind study
C) Neither
Answer:
Double blind study.
Step-by-step explanation:
We are told that participants receive contents from Bottle A, Bottle B, or Bottle C.
However, the testing service only knows that one bottle contains placebo aspirin but they don't know the other contents nor which of the participants is taking the one with placebo aspirin.
Thus, this is a double blind experiment because neither the participants nor the testing service have knowledge of who is taking the bottle that contains placebo aspirin unlike a blind experiment where the testing service will know which participants got the bottle containing aspirin.
This is the concept of algebra, the denominator of y+(y-3)/3 will be as follows;
the expression y+(y-3)/3 can be written as:
y/1+(y-3)/3
the denominator of the first term is 1 and that of the second denominator is 3, to get the common denominator for both terms we multiply both denominators;
thus the common denominator will be:
3*1=3
thus the our common denominator will be 3:
Divide 21 by 8. and then whatever the reminder comes will go as the whole number
and the reminder will be the numerator and the number 8 will be the denominator.
the answer is 2 5/8
2 is the whole number, 5 is the numerator and 8 is the denominator
<span>(2/3)(9/5)(5/4)
= (2*9/3*5)</span><span>(5/4)
= (18/15)(5/4)
= 18*5/15*4
= 90/60
= 9/6
= 3/2

The amount of Protein intake is 900 kilocalorie.
We have - 2000 Kilocalories of diet and 45 Percent of calories come from Proteins.
Wе have to find out the amount of protein intake.
<h3>If ' x ' students out of total ' n ' students in a class are infected by virus. Then, what percentage of students are infected.</h3>
Percentage of students affected are - 
In the question given -
Let the amount of Protein intake be y.
Then -
45 = y % of 2000
45 = 
y = 
y = 900 Kilocalorie
Hence, the amount of Protein intake is 900 kilocalorie.
