The table displays a probability distribution of the number of pets in a student's home. find the standard deviation of the probability distribution.

idk

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

my dude, this isn't answerable due to the fact there is no question or clear desc of what you want them to do.
