The range is the possible y-values of the graph. If you have a specific equation, post it.
Answer: a=36; b=18
Step-by-step explanation:
1. You know that the sum of two numbers is 54, then, you have:
a+b=54
2. According to the problem, the larger number is 18 more than the sampler number, this can be expressed as following:
a=b+18
3. Then, you must substitute the second equation into the first equation and solve for b:
b+18+b=54
b=18
4. Then the value of a is:
a+18=55
a=36
To find what 25 percent of 130 is we must convert 25 to a decimal. 0.25
Then we multiply .25 and 130 to get 32.5 dollars off 130. This means that the radio and earphones will cost $97.50 and you will have $2.50 remaining.

Step-by-step explanation:
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.
