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
The 5 number that have 3 ,5 and 7 as prime number are 23, 31, 37, 43, 53. and if you want there 57,47, 103.
(x - 2)^2 will always be positive and will have a minimum value of 0
so f(x) will have minimum of 2
Range is [2,∞)
3x+y=17
=> 3x=17-y
Again, x+3y=-1
=> 3y= -1-x
now, 3x+3y= (17-y)+(-1-x)
= 17-y-1-x
= 16-x-y
Answer:
I think the answer would be n×0.99
Step-by-step explanation:
the answer will be n×0.99 because she bought for example n=7 each for 99 cents. to find the total you would have to do 7x0.99. Hope this help you
