No, he is only studying a small percentage out of 2500 kids. His study isn't large enough to count.

Answer:

not a valid study

Step-by-step explanation:

Given that

Kai is conducting a study about the percentage of students with jobs. His school has 2500 students. He asks everyone in his drama class to participate in a survey. He bases his findings on these results.

Just selecting only students in his drama class to form the sample will not give accurate results since samples are not drawn at random.  The sample done is convenient sample saving time, but failing to represent the entire student population with jobs.

THe best sample would be group the students with jobs and select from the group at random a sample size proportional to the population size.

olganol [36]
Ben wanted to take some money from his Friends to build his family a home. He said that he would give the money back after 12 months. So he would give 1500$ a month. How much money did he borrow?
1500*12=x

Matilda got also money, she told Ben, I got x $ from my dad and y $ from mom. all they gave me was 5000$. If I gave mom Half of the moneys I got from her than I would have 3000$ left to pay. How much did she borrow from her parents?
x+y=5000
and
x+y/2=3000

so x=5000-y
and
5000-y+y/2=3000

so
x=5000-y
and
y=4000

so x=1000 and y=4000
