Cross sectional study

A friend wants to explore age differences in happiness for her ph.d. thesis. she should most likely conduct a cross sectional study, because it will demand less time than the other types of study.

An observational research method known as a cross-sectional study examines data on variables that were gathered at one specific moment across a sample population or a pre-defined subgroup.

Cross-sectional analysis study can also be called transverse study, or prevalence study. Although cross-sectional research does not involve conducting experiments, researchers often use it to understand outcomes in the physical and social sciences and many business industries.

tammy and lia work in retail, in different shops. Tammy makes $7 per hour plus $4 for each item she sella, and Lie makes $10 per

Tatiana [17]

<h3>So lets say y = The amount of money that's made and x = The number of hours worked. We need two equations. one for Tammy and one for Lia. Tammy's equation will be: y=7x+4 because she makes 7 dollars an hour plus 4 dollars for every item she sells. Lia's equation should be: y=10x+3 because she makes 10 dollars an hour plus 3 dollars for every item she sells. Now since we need to know when they will make the same amount of money, we put both the equations together to make 7x+4=10x+3. Now lets use the distributive property to solve that equation. </h3><h3>7x+4=10x+3</h3><h3> -4 -4</h3><h3> 7x=10x-1</h3><h3> -10x -10x</h3><h3>-3x=-1</h3><h3>x=0.3 repeated)</h3><h3>Now we plug x into Lia's equation and solve that.</h3><h3>y=10( $\frac{1}{3}$ )+3</h3><h3>y=3.33+3</h3><h3>y=6.33</h3><h3>Now we write our answer as an ordered pair: (0.33, 6.33) </h3><h3>Buuuuuuuuuuuttt you can't have 0.333333333333 of an item so the final answer here would be NO SOLUTION.</h3>
