Use the balanced scale to find the conversion factor that can be used to convert the number of blocks to the weight of the blocks, in pounds?

Oh wow, i posted an answer with a full on explanation as to why it was correct, and the person above me just puts, "1.5" and their answer doesn't get taken down? yeah so fair.

thanks

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.

4+3x is the answer

hope you got it
