Jason earns $6.00 an hour babysitting.
Jason earns $7.75 an hour working at a store.
He can work no more than 40 hours each week.
Let b equal hours of babysitting, and s equal hours working at the
store.
Which system of inequalities models the constraints?
O 6.00b + 7.755 2 250
b +5 s 40
O 6.00b + 7.75s 250
b +5 s 40
O 6.000 + 7.75s 40
b + s 250
O 6.00b + 7.75s 2 40
b + s 250

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
