A cohort study on the effectiveness of a treatment for alcoholism will follow 50 people for two years. In this time, it is expected that the number of people who drop out of the study due to relapse will be ten, with standard deviation four. It is also expected that the number of people who drop out of the study because they move out of the study area will be six, with a standard deviation of three. What is the SD of the number of people who will drop out due to either relapse or moving away? g

a 10 percent increase

how is that middle school

step-by-step explanation:

how am i supposed to answer

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
