How to find the normal vector of a plane.
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.
dont think so
step-by-step explanation:
to find the perimeter of the rectangle this is the expression:
x-9+x-9+3x-4+3x-4=138
if we simplify it:
8x-26=138
remember, 138 is what it all adds up to
the length is 11.5cm
the width is 57.5cm
the area is 661.25cm^2
