Mean absolute deviation of 103,171,115,165,124,170,125

41.1

Step-by-step explanation:

Mean: 103 + 171 + 115 + 165 + 124 + 170 + 125 = 973/7 = 139

139 - 103 = 36

103 - 171 = 68

103 - 115 = 12

103 - 165 = 62

103 - 124 = 21

103 - 170 = 67

103 - 125 = 22

36 + 68 + 12 + 62 + 21 + 67 + 22 = 288/7 = 41.1

step-by-step explanation:

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
