Answer: I think its A If you do the math corrcetly
Step-by-step explanation:
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.
Answer:
A parabola opens downward with vertex at (1,20)
Step-by-step explanation:
The function that models the height of bag of candies is
The graph of this function is a parabola that opens downward.
To find the maximum height of the candy bag, we complete the squares to obtain the vertex form of the function.
Factor -16 to get;
Add and subtract the square of half the coefficient of t.
Factor the perfect square trinomial:
The vertex is (1,20)
This means the maximum height after 1 second is 20 feet.
Answer:
y=13/11+17x/11 (these are fractions)
Step-by-step explanation:
Move all terms that don't contain
y
to the right side and solve.
Since the truck is 8 feet long then the longest log able to fit in the truck should be 8 feet as well. However talking reality, we might want to shorten it to make it fit better. Hope this helps!
