Write a rule that expresses the number of quarts q of a liquid as a function of the number of pints p.

1q = 2p

Step-by-step explanation:

One quart of liquid is the equivalent of 2 pints... one of the rare easy measures in the American measure system.

So, the equation needs to have 1 quart on one side, and 2 pints on the other side.  It's an equation because both values are equal, just expressed in different units.

1 quart = 2 pints, then rewritten to match the variables given in the question:

1q = 2p

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.
