Tutorial 13: Working with multiple elements of a graph This tutorial has presented the basic types of Interactions you will encounter with graph questions. However, many graphing questions will require you to draw multiple objects on a single graph. For example, you may be required to draw a line, label some points, and highlight an area, all on the same graph. Because there are many questions that will require multiple Interactions, this tutorial gives you the opportunity to practice using multiple Interactions on a single graph. Be sure to read the graph Instructions carefully. Instructions: 1. Use the line tool 'Quota' to draw a vertical line at a quantity of 2 units. Draw this line so the lower end point touches the horizontal axis (2,0) and the line intersects and extends beyond the demand curve. 2. Use the reference point tool 'B' to identify the new price and quantity at coordinate (2,6). 3. Use the shading tool 'Fill' to shade in a triangular area at the points or vertices of (0,8), (2,6), and (0,6).

Can you help me graph that information

Alex is a hard-working college sophomore. One Saturday, he decides to work nonstop until he has answered 50 practice problems for his economics course. He starts work at 8:00 AM and uses a table to keep track of his progress throughout the day. He notices that as he gets tired, it takes him longer to solve each problem. Time Total Problems Answered 8:00 AM 0 9:00 AM 20 10:00 AM 35 11:00 AM 45 Noon 50   Use the table to answer the following questions. The marginal, or additional, gain from Alex’s second hour of work, from 9:00 AM to 10:00 AM, is   problems.   The marginal gain from Alex’s fourth hour of work, from 11:00 AM to noon, is   problems.   Later, the teaching assistant in Alex’s economics course gives him some advice. “Based on past experience,” the teaching assistant says, “working on 7.5 problems raises a student’s exam score by about the same amount as reading the textbook for 1 hour.” For simplicity, assume students always cover the same…

As part of its bankruptcy restructuring, General Motors (GM) launched an ad campaign that revealed glimmers of a streamlined GM: fewer brands (Cadillac, Buick, Chevrolet, GMC) and fewer models within each brand A. What research would you have done to determine which vehicle models GM should retain and which it should drop? B. What would you have measured and with what type of measurement scale?
