In July, Jannat did yard work for a total of 26 hours. For all the hours Jannat worked, she earned $234. How
much money did Jannat make per hour doing yard work?
$7/hr
B
$9/hr
$15/hr
D
$35/hr

$9/hr

Step-by-step explanation:

Find how much she earned by dividing 234 by 26:

234/26

= 9

So, Jannat made $9 per hour.

Jannat had to work $9/hr for 26 hours in order to earn $234

How to solve this problem: Times 26 by 9 it will equal 234.

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.
