A company opened this past year. They have a 24 hour customer service department. The company is looking to reduce costs and is considering closing its customer service department between the hours of midnight at 5am. Before making this decision, they want to gather some information about the usage of this service during these hours. They pull the data from the number of calls to customer service for each day since the company began. Number of Calls to Cust Service Number of Days 0-14 32 15-29 64 30-44 58 45-59 46 60-74 68 75-89 32 What is the mean number of calls to customer service

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
