Answer

Explanation:

Question 1a

The dependent variable is the one that depends on another variable. In a price - demand graph, quantity demanded depends on price. Quantity demanded

Question 1b

Examine the graph. As price goes from $3 to $4, demand increases but price decreases. No

Question 1c

Locate the price of $5 on the x - axis and read the corresponding demand value on the y - axis. 15 (per week)

Question 2a

Estimate the number of students in each major from the bar - graph and sum them up. Approximately 1100 students (150 + 100+350 + 250+250, with an allowance of ±50)

Question 2b

Identify the tallest bar in the bar - graph representing majors. Econ

Question 2c

Read the height of the bar corresponding to Physics from the bar - graph. 100

Question 2d

Find the number of students in Poly Sci and Psych from the bar - graph and subtract. 250 - 200 = 50

Question 3a

Locate March 1989 on the graph and read the rainfall value. 3 inches

Question 3b

Find the rainfall in Feb 1990 and Feb 1989 and subtract. 6 - 2 = 4 inches

Question 3c

Compare the total rainfall for each year by visually assessing the graph. 1990

Question 3d

Identify the highest point on the graph for each month across the two years. April 1990

Answer:

1a. Quantity demanded 1b. No 1c. 15 (per week) 2a. Approximately 1100 students 2b. Econ 2c. 100 2d. 50 3a. 3 inches 3b. 4 inches 3c. 1990 3d. April 1990
