Answer:
Option E
Step-by-step explanation:
Single-blinding refers to a kind of clinical trial in which only the researcher conducting the study knows which treatment or the participant is receiving until the trial is over.
Control Group refers to the group in an experiment that does not receive treatment by the researchers, it is used as a benchmark to measure how the other tested subjects do.
Under the random assignment, the study participants are randomly allocated to different groups, such as the experimental group, or treatment group.
Confounding can be controlled by adjusting for it after completion of a study using stratification or multivariate analysis.
The treatment group refers to the experimental groups that receive treatment in an experiment. The “group” is made up of test subjects (people, animals, plants, cells, etc.) and the “treatment” is the variable under study.
Since here we are making groups to perform the experiment away from the main workforce, the feature used here is the treatment group.
Remember that multiples are numbers that can be divided by a number without a remainder so in this case you could add 15 by 15 to find what number in this set is a multiple of 15.
Therefore your answer is "60."
Hope this helps.
The answer is 12/5

Answer:
1. 10n
2. 3x^2z^2
3. 2(9n^3 - 3n^2 + 3n - 1)
4. (Put the same thing)
5. There are no common factors so it is completely factored out.
Step-by-step explanation:
For 1, you gotta find the gcf of the numbers and the variables. So, the common factor of 90, 70, 70, and -80 is 10. Nothing else greater than 10 divides these numbers. For the variables, only "n" is the GCF, as there is one "n" and all the other numbers have n^2 and etc.
For 2, same thing, you have to find the gcf for the numbers and the variables.
3. same thing ;-; (gcf is 2 btw, nothing divides the variables because 2 has no "n".
4. theres nothing that divides the numbers or the variables. So, the gcf is just 1.
Answer:
42 = the number of hats Paula can knit from one yard of yarn
Step-by-step explanation:
The way this problem is written, the constant 42 is the multiplier of yards to get hats. That is, it has units of hats per yard, so represents the number of hats that can be knit from 1 yard of yarn.
_____
<em>Comment on the problem</em>
It seems more likely that the proportion should be written as ...
y = 42h
or
h = y/42
Then the constant would be the number of yards of yarn required for each hat.
