Consider the following system of equations. E (-10x2 - 10/2 --300 5x2 +5y2 - 150 Which statement describes why the system has infinite solutions? O The equations represent parabolas that result in graphs that do not intersect. O The equations represent circles that result in graphs that do not intersect. The equations represent parabolas that result in the same graph O The equations represent circles that result in the same graph Hanks and ཀལ། Save and Exit

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19

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.
