Experimental methods involve the manipulation and control of variables, whereas non experimental methods require simple observation of the variables.
Answer: Option D.
<u>Explanation:</u>
Non-experimental research about doesn't mean nonscientific. Non-experimental investigate implies there is an indicator variable or gathering of subjects that can't be controlled by the experimenter. Test plan, then again, takes into consideration specialists to control the indicator variable and subjects.
Non experimental research falls into three broad categories: single-variable research, correlational and quasi-experimental research, and qualitative research.
There are two people in this problem and both of them get time for playing if they complete the homeworks in their allotted time.
Taking the first instance of Jonathan
For every 5 hours of doing homework, the number of hours Jonathan
gets for playing video games = 3 hours
Then
For every 1 hour of doing homework, the number of hours Jonathan
gets for playing video games = (3/5) * 1 hours
= 3/5 hours
= 0.6 hours
= (0.6 * 60) minutes
= 36 minutes
Taking the second instance of Lucas
For every 1 hour of doing homework, the number of minutes Lucas
gets for playing video games = 30 minutes
Then we can easily say that if both Jonathan and Lucas spend the same amount of time doing homework, then Jonathan gets more playing time than Lucas.
Answer:
(x, y) = (2, 5)
Step-by-step explanation:
I find it easier to solve equations like this by solving for x' = 1/x and y' = 1/y. The equations then become ...
3x' -y' = 13/10
x' +2y' = 9/10
Adding twice the first equation to the second, we get ...
2(3x' -y') +(x' +2y') = 2(13/10) +(9/10)
7x' = 35/10 . . . . . . simplify
x' = 5/10 = 1/2 . . . . divide by 7
Using the first equation to find y', we have ...
y' = 3x' -13/10 = 3(5/10) -13/10 = 2/10 = 1/5
So, the solution is ...
x = 1/x' = 1/(1/2) = 2
y = 1/y' = 1/(1/5) = 5
(x, y) = (2, 5)

The attached graph shows the original equations. There are two points of intersection of the curves, one at (0, 0). Of course, both equations are undefined at that point, so each graph will have a "hole" there.
24/2=12 so you would do 120/12 and get 10. Your answer is 10 hours.
