Answer:
Step-by-step explanation:
Refer to the attached figure. Note that the solution set is shaded, and includes all points on the solid boundary line.
black point (-1,1) is outside of the solution set
Red point (1,-1) is also outside of the solution set.
Yellow point (3,2) is on the solid boundary line, so it is part of the solution set
Blue point (2,3) is outside of the solution set.
You can comment below, are these supposed to be simply equations or piecewise functions?
The plot for January places the median age at 40, so half of the surveyed group was over 40. That would be half of 100 people, or 50 people.
The plot for July places the upper quartile at age 40, so 1/4 of the surveyed group was over 40. That would be 1/4 of 100 people, or 25 people.
There were 50 - 25 = 25 more visitors over the age of 40 at the beach in January.
