Out of 400 students sampled, 300 of them said that they hoped to have children someday. with 99.7% confidence, what is the approximate percentage of the students in the population who hope to have children someday?

Which equation represents a line that is parallel to the line whose equation is 3x-2y=7( show all work)

What numbers are included in the set of integers? what numbers are not included?

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.
