Find the mean, median, and mode 15, 3, 11, 15, 1, 14, 7, 2, 1, 1, 2 a. mean = 6.5, median = 8, mode =1 b. mean = 6, median = 3, mode = 1 c. mean = 6, median = 3, mode = 8 d. mean = 6.5, median = 3, mode = 1

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
