If 25 students took an exam and 4 of the students that took the exam failed, what percent of the students passed?
To find out how many students passed, we can subtract 4 from 25 and we will get a difference of 21.
The fraction 
represents the number of students who passed the exam out of all the students.
To find out what percent of the students passed, we can turn into a percent.
21 ÷ 25 = 0.84
0.84 × 100 = 84%
Therefore, 84% of the students who took the exam passed.
Answer:
184 
Step-by-step explanation:
Surface area = 
· h / 3
Surface area = 55.2 · 10 / 3
Surface area = 552/3
Surface area = 184
Final answer: 184 
Answer:
An independent sample.
Step-by-step explanation:
In this scenario, to compare the production techniques used by foreign and local firms in Brazil, a random sample of 80 foreign firms and a random sample of 80 local firms are selected. We can safely conclude that this study uses an independent sample design.
An independent sample design can be defined as a research method that usually involves the use of multiple experimental groups (two or more). The samples or participants are only in one group and as such each group has no relationship with the other. This simply means that, the samples in a particular group is having no relationship with the other samples in another group.
Ultimately this implies, each samples are independent and satisfies only one condition of the independent sample design during the experiment to compare the production technique used by foreign and local firms in Brazil.
<em>Hence, the researcher would use only two variables or conditions: a random sample of 80 foreign firms and a random sample of 80 local firms are selected.</em>
