The diagram at the right shows the orthocenter of an acute triangle. Drag vertex C to form a right triangle and an obtuse triangle. Which statements are true about the orthocenter? Check all that apply. It lies inside an acute triangle.
It lies inside a right triangle.
It lies on a right triangle.
It lies on an obtuse triangle.
It lies outside an obtuse triangle.

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.

Select the margin of error that corresponds to the sample mean that corresponds to each population: a population mean of 25, a standard deviation of 2.5, and margin of error of 5%
