The decimal 0.38 is represented as the fraction 19 over 50
Equation t= $7 times w
$7 times 4 = $28
The value of the digit 4 is worth 4,000 in the number 84,230.
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
