A student may participate in football or golf. About 13% of the student body at a high school participates in football. About 8% plays golf. What is the probability that a student chosen at random participates in either football or golf? 5%

104%

13%

21%

21%

Step-by-step explanation:

The sum of the 13% who play football and the 8% who play golf would be 21%

.13 + .08 = .21

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
