yes is is proportional
x=ydivided by 3.5
Step-by-step explanation:
Answer:
The next numbers go up by 8, 16, and 32. So they double everytime.
So the answer would be 125.
Answer:
D.12
Step-by-step explanation:
sorry I just know its 12 I promise
Answer:
Angle L*; 67.5 degrees
Angle S*; 22.5 degrees
Step-by-step explanation:
Angle L is 3 times bigger than Angle S.
With this information, we can make an equation.
L=3S
Complementary angles add up to 90 degrees.
90 = 3S + S
90 = 4S
22.5
Angle S equals 22.5.
Because Angle L is 3 times bigger than Angle S, we multiply 22.5 by 3.
This gives us 67.5.
Angle L is 67.5 degrees
Angle S is 22.5 degrees
Now, in order to check our work, we add the two angles together.
67.5 + 22.5 = 90
Because they add up to 90 degrees, the complementary angles work with each other meaning that we are correct
*Angle L is the larger angle
**Angle S is the smaller angle
Answer:
To remove the bias
Step-by-step explanation:
The study in which neither the subject nor the experimenter knows which subject is receiving a particular treatment is known as double blind study.
In the given study, the treatment is caffeine pills. So neither the subjects know they received caffeine pills nor the experimenter knows that which subject received which pill. Hence, this is a double blind study.
Such a study is used to remove the potential bias from the study. For example, if a subject is told that he is given a caffeine pill his actions will re-enforce that he has taken the pill, even in the case when he is given a placebo instead of actual pill. So the belief of the subject may cause bias in the result. This is removed by using the double blind study.
Also, since the experimenter also does not know which subject received the treatment, they won't act in different ways towards different subjects to give away any hints or clue. If the experimenter knows which subjects is given actual treatment, he may behave differently with him. So the double blind study removes this sort of bias as we..
