A survey was given to a random sample of the residents of a town to determine whether they support a new plan to raise taxes in order to increase education
spending. The survey reported a confidence interval that between 20.5% and 29.5%
of the residents supports the plan. What is the margin of error on the survey? Do not
write = on the margin of error.

Find the number of real number solutions for the equation. x2 + 5x + 7 = 0 0 cannot be determined 1 2

How do you solve a question like this?

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
