1)) What is the length of the hypotenuse?
C =
meters

  20 m

Step-by-step explanation:

Assuming the given dimensions are the leg lengths of a right triangle, the hypotenuse is given by the Pythagorean theorem:

  c² = a² + b²

  c² = (12 m)² +(16 m)² = (144 m²) +(256 m²) = 400 m²

  c = √(400 m²) = 20 m

The length of the hypotenuse is 20 m.

You can recognize that the side length have the ratio 3:4, so are part of a 3:4:5 right triangle with a scale factor of 4 m. They hypotenuse is 5×4 m = 20 m.

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.
