A student conducts a survey on the eye color of a group of ninth-graders and then randomly selects a ninth-grader. Compare the experimental probability of choosing a ninth-grader with blue eyes to the experimental probability of choosing a ninth-grader with hazel eyes.

Eye Color Blue Brown Green Hazel
Number 37 62 13 15

75

Step-by-step explanation:

blue : brown : green : hazel

37    :     62    :    13      :   15

37 + 62 + 13 + 15 = 127

hazel (15 ) + blue (37) = 52

127 - 52 = 75

The probability is 75/ 127

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
