Answer:

So then the difference between the two proportions is 0.045 and if we convert this into % we got

Step-by-step explanation:
For this case we can define the following notation:
represent the unemployment rate for high school graduates with no college degree
represent the unemployment rate for college graduates with a bachelor's degree
And for this case we need to find the difference in proportions of those unemployed between these two groups, we want to find:

From the info given we have 

And the difference:

So then the difference between the two proportions is 0.045 and if we convert this into % we got

All because -2.22 is a real number, it’s a rational number because it can stop and a integer because it’s negative
From this picture you can calculate coordinates of triangles' vertices:

.
Since
you can conclude that points A, B, C are rotated by

about the point (-0.5,0) to form points J, G, H, respectively.
Answer: A is correct choice.
