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
I think that this quesion is missing some background, that is that Ms. Donaldson earned 907.10
So the 34.55 were deduced from this number, and the remaining amount was:
907.10-34.55=872.65
After this, further 28% were deduced, which means that 100-28=72% were left.
And this is:72%*872.55= 628.236 (which we round to 628.24!)
Answer:
Second option is the correct answer
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
Here, we want to find the value of ;
h circle h(10)
This mean we are to put h in h, the find the function of 10
we have this as;
6-(6-x)
= 6-6 + x = x
Now, replace the x by 10; so we have h circle h(10)
