When constructing a perpendicular line through a point on a line, how can you verify that the lines constructed are perpendicular?
check the angles used in the construction with a straightedge to ensure consistency.
check the distance along the lines at several places with a compass to ensure they are the same length.
check the intersecting lines with the corner of a piece of paper to ensure the lines create 90° angles.
check the distance between the lines at several places with a compass to ensure they are equidistant.

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
