Scores on the Critical Reading part of the SAT college entrance test in a recent year were roughly Normal with mean 1003.3 and standard deviation 189.8 . You choose an SRS of 110 students and average their SAT scores. If you do this many times, the mean of the average scores you get will be close to

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

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

answer is b
