As part of a study on facility needs, the administrators of a university wanted to estimate the percent of students who use the exercise facilities on a regular basis. from the 34,000 students who attend the university, a random sample of 370 male students and 400 female students was selected. of the 770 students selected, 493 students indicated that they use the exercise facilities on a regular basis. what are the population and the sample of the study?

Population = 34,000

Sample = 770

Step-by-step explanation:

Population: Total number of students who attend the university

Sample: A portion of total students selected to conduct the study and generalise the conclusions to the entire population.

Population = 34,000 students who attend the university

Sample = 770 students (400 female + 370 male) randomly selected

Therefore, the population of the study is 34,000 and the sample is 770.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
