Answer:
x=2,y=0
(You did not provide enough information for me to know what to do with said equations, so I'm assuming it was System of Equations.)
We Can Let "A Number" Be M.
M Divided By 3 Less Than Itself Gives Quotient Of 8/5.
M/(M-3) = 8/5. Lets Solve.

So, What Number Can Have 3 Subtracted From It To Get Five, But Also Be Equal To Eight?
Eight Of Course!!!
So, We Know That The Number Equals 8.
Answer:
This is an example of causation because the patient that took the medication recovered quicker than the patient that did not.
Step-by-step explanation:
Correlation is a statistical technique that shows that a relation exists between 2 variables but does not give any explanation about the relationship
Example: Correlation between Air Conditioner sales and sunglasses sold.
As the sales of the air conditioner is increasing so do the sales of sunglasses.
Causation is a statistical technique that shows a relation ship between 2 variable. It emphasizes the fact that any change in the value of one variable will cause a change in the value of another variable.
Answer:
One possible confound for the experiment is the attitude of the research assistants.
Step-by-step explanation:
A confounder simply means a variable that has impact in influencing both the dependent variable and independent variable, causing a spurious association.
So, we can conclude that the attitudes of the research assistants have positive and negative impacts in determining the reactions of both participants in the experiment.
The rudeness of a research assistant will negatively impact the response of the participant allocated to him/her.
The calmness of the other research assistant will positively impact the response of the participant allocated to him/her.
