Answer:
15000
Step-by-step explanation:
Given that a professor wants to know how undergraduate students at X University feel about food services on campus, in general. She obtains a list of email addresses of all 15,000 registered undergraduates from the registrar’s office and mails a questionnaire to 300 students selected at random.
Only 150 questionnaires are returned.
So the sample size changed to 150. But population is the number of registered undergraduates which do not change.
Population size = 15000
Example:
You owe someone $45.75 which is -45.75. You are able to pay that person the $45.75 which is positive and equivalent to the amount of money you owe. Add them together and you will get 0, meaning you don't owe them any money anymore.
First make the equation equal y
Y=-2x-6
Then rearrange to make x the subject
2x=-y-6
X=(-y-6)/2
Then change the y's to x's
Inverse=(-x-6)/2
