I hope this is right, but I think it should take a remaining six hours for the new guy to fix your car. He worked on it for two hours with the other mechanic, but it still takes him 8 hours total to fix the car. So he still has six more hours to fix your car. Again, I hope this is right.

Given:
The side of square = 12 in.
Scale factor of enlargement = 3 in : 2 m
To find:
The proportion that is use to solve the side length, x, of the enlarged square.
Solution:
Let, the side of length of enlarged square = x m
In case of enlargement the corresponding sides are proportional.
![\dfrac{3}{12}=\dfrac{2}{x}](https://tex.z-dn.net/?f=%5Cdfrac%7B3%7D%7B12%7D%3D%5Cdfrac%7B2%7D%7Bx%7D)
![3x=2\times 12](https://tex.z-dn.net/?f=3x%3D2%5Ctimes%2012)
![3x=24](https://tex.z-dn.net/?f=3x%3D24)
Divide both sides by 3.
![x=\dfrac{24}{3}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B24%7D%7B3%7D)
![x=8](https://tex.z-dn.net/?f=x%3D8)
Therefore, the required proportion is
and the side length of the square after enlargement is 8 m.

Answer:
(a)High school students in the United States.
(b)100 Students
(c)Statistic
Step-by-step explanation:
(a)Since the researcher is interested in the texting habits of high school students in the United States, the population for this study consists of all high school students in the United States.
(b)It is most often improbable to carry out research on an entire population of study. A <u>sample is taken to represent the population</u> and the results obtained from the sample are assumed to hold for the entire population.
In the given study, the researcher selects a group of 100 students to represent the High School students in the United States. This is the sample for the study.
(c)The researcher calculated the average number of text messages that each individual sends each day from the sample of 100 Students. This is an example of a Statistic. A statistic is a numerical data obtained from a sample.
Note: If the data were obtained from the entire population, it would be a <u>parameter.</u>
