Agumball machine has 15 red, 13 blue, 16 yellow, and 6 orange gumballs. what is the probability, expressed as a percent, of getting a blue gumball?

26 percent

Step-by-step explanation:

total number of gumballs

15+13+16+6 = 50 gumballs

to find the percent of blue gumballs

blue/total * 100 = 13/50 * 100 = 26 percent

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.
