When David first got a job, his annual income was $20,000. He worked hard and got more experience. After 8 years, he realized that his average increase in pay was about $4,000 every year. Which scatter plot represents this situation?

there are no graphs attached, so i can't pick an exact answer, but if plato/edmentum users have 4 graphs, its the second graph from the first row. (basically the top right graph.)

the graph i'm saying is the answer contains: first red dot below the line above 1, a second red dot above the 2 and the line, a third red dot above the 3 but below the line, a fourth red dot above the 4 and the line, a fifth red dot above the 5 but below the line, a sixth red dot above the 6 and the line. thats as clear as i can possibly explain the answer. (you can ignore the 123456 if you want).  

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
