Answer:
Suppose you want to assess student attitudes about the new campus center by surveying 100 students at your school. In this example, the group of 100 students represents the Sample, and all of the students at your school represent the Population.
Step-by-step explanation:
Previous concepts
The term sample represent a set of observations or individuals selected from a population. And we can have a random sample (when all the individuals have the same probability of being selected) or a non random sample (when not all the individuals have probability of inclusion into the sample)
The term population represent the total of observations or individuals with a common characteristic.
If N represent the sample of the population and n the sample size we have always this inequality:
Solution to the problem

Number of general admission tickets sold is 75
<u>Step-by-step explanation:</u>
Step 1:
Let the number of general admission tickets be x, then the number of student ID tickets = 200 - x. Total cost of tickets sold = $625
Cost of general admission tickets = 5x
Cost of student ID tickets = 2(200 - x) = 400 - 2x
Total cost of tickets = 5x + 400 - 2x = 625
⇒ 3x + 400 = 625
⇒ 3x = 225
⇒ x = 75

Step-by-step explanation:
1. the image is multiplied by the scale factor. if the scale factor is 2, the image is twice the size of the preimage. if the scale factor is ⅓, the image is one third the size. only a scale factor of 1 preserves congruency
