#3 The question says the sun of two consecutive integers is 345. What are the integers? #5 The sum of two consecutive even integers is 446. What are the two. integers?
Need help please

Step-by-step explanation:

#3 let the two consecutive integers be a, a+1.

a+a+1=345

2a+1=345

2a=345-1

2a=344

a=344/2=172...

the integers are 172, 173

#5 let the consecutive even integers be a, a+2

a+a+2=446

2a=446-2

2a=444

a=444/2=222..so the even integers are 222, 224

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.
