　　Explanation

　　3.The correct answer is B

　　Figures in a Coordinate Plane

　　The figure provides all the information you need to answer the question.

　　What Is the Question Asking?

　　You are asked to figure out the area of a triangle that is defined by the points in a coordinate plane.

　　What Do You Know?

　　The triangle in the figure is a right triangle with the right angle at the lower left.

　　Because it is a right triangle, its base and height are the two sides that form the right angle.

　　4.The correct answer is A

　　Choice (A) is correct. There are 5 + 6 + 5 + 8 + 6 + 1 = 31 employees represented in the graph. If the employees are put in order according to the number of days spent on business trips from least to greatest (or from greatest to least), the median number of days spent on business trips is the number of days spent by the employee in the middle of the list. Since 312 = 15.5, this is the 16th employee (there will be 15 employees before and 15 employees after the 16th employee in a list of 31 employees). From the graph, it can be seen that the 16th employee is in the group that spent 22 days on business trips (since 5 employees spent 20 days on business trips, 6 employees spent 21 days and 5 employees spent 22 days). Therefore, the median number of days spent on business trips in 2010 for these employees is 22.
