• drawCircle(200, 300, 50, Color.purple);

• drawCircle(50, Color.purple, 200, 300);

• drawCircle(200, 300, Color.purple, 50);

• drawCircle(radius, color, x, y);

Consider the following array:

Why do we compress data?

I. To save memory space on devices

II. To speed up the time it takes to send a file over the internet

III. The computation it takes to decompress data is cheaper than the storage space required to store uncompressed data

• I only

• I and II

• I, II, and III

• III only

Which of the following are true about Internet routing?

I. For any two points on the Internet, there exists only one path between the two points

• Neither I and II

Which of the following statements are true about using visualizations to display a dataset?

I. Visualizations are visually appealing but don’t help the viewer understand relationships that exist in the data

II. Visualizations like graphs, charts, or visualizations with pictures are useful for conveying information, while tables just filled with text are not useful.

III. Patterns that exist in the data can be found more easily by using a visualization

• I and II

• II and III

• I, II, and III

• III only
