Amagazine provided results from a poll of 500 adults who were asked to identify their favorite pie. among the 500 respondents, 14% chose chocolate pie, and the margin of error was given as plus or minus5 percentage points. describe what is meant by the statement that "the margin of error was given as plus or minus5 percentage points." choose the correct answer below. a. the statement indicates that the study is only 5% confident that the true population percentage of people that prefer chocolate pie is exactly 14%. b. the statement indicates that the study is 100%minus5%equals95% confident that the true population percentage of people that prefer chocolate pie is 14%. c. the statement indicates that the interval 14%plus or minus5% is likely to contain the true population percentage of people that prefer chocolate pie. d. the statement indicates that the true population percentage of people that prefer chocolate pie is in the interval 14

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

irrational, cannot

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
