These ad agencies must focus on their target audience, which are the students. Hence, they should gather data on the pool that will surely comprise of students. For agency B, social media posting is not a good source pool. It's true that students are very participative and opinionated in social media. However, they can't be sure that these are students. Some parents are in social media, as well. Some are working individuals, and some are out of school youth. Unlike agency A, agency B has to sort out profiles first and identify which ones are students. Hence, agency A will produce a fair sample of the student population because it is unarguably true that everyone in the school enrollment data are students.
The answer is B.

The scale of a drawing is the RATIO that all parts of an object are reduced or magnified by
Answer:
16,800 Liters
Step-by-step explanation:
Convert 3/4 into eighths, because it was already 1/8 full before the 10,500 liters were added:
3/4= 6/8
Subtract 1/8 from that (because it was already 1/8 full):
6/8-1/8= 5/8
Divide 10,500 by the 5 (because you want how many liters each part is):
10,500/5= 2,100
You know can say that every eighth is 2,100 Liters of water.
Multiply that by the 8 total parts it can hold:
2,100x8= 16,800 Liters
To find that one, just look at the highest exponent. In the given equation that would be 4, so there can be at most 4 zeros in this function.
