Four students conducted a survey about sports preferences at their middle school. Each student asked participants in their survey the same questions.
• Brian surveyed all the students in the school clubs.
• Ellen surveyed 10 different students in all of his classes that he had in the morning.
• Karter surveyed all the seventh graders who were eating sandwiches in the cafeteria at
lunchtime.
• Olivia surveyed each fifth person from a list containing alphabetized names of the
students in the school.
Which student’s survey would most likely be representative of sports preferences at the
school?

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true

the answer i believe is 27 units.
