Answer:
The first and third answers are correct
Step-by-step explanation:
First answer=11/4=2.75
Second answer=4/9=0.444...
Third answer=4/3=1.333...
Fourth answer=5/9=0.5555555556
2/3=0.66666666667

Answer:
B. The observational study is a cross-sectional study because information is collected at a specific point in time.
Step-by-step explanation:
1) There are three types of Observational Studies: Case-control, cross-sectional and Cohort.
2) Since the researchers collected information from those 1800 adults at a certain time, then we can call it a cross-sectional study. It does not provide solid results since the research was not done over a period to collect further information. We don't know, for example, much more than what that association deeply mean.
3) If we wonder more, then the researchers would have to track those adults over a given period, i.e. a Cohort would be necessary.
4) Moreover, it's not "retrospective" for virtually every question, always makes us look back somehow, and it does not categorize a kind of observational study.
P=rt+0.16s
365=20r+0.16(1500)
365=20r+240
125=20r
r=6.25
So Piper makes $6.25 an hour.
