There are eight boys and eight girls in a dance troupe at the beginning of each class, the teacher randomly pick a person to lead warm ups. the teacher has picked a boy 48 times and a girl 32 times. what is the relative frequency of picking a girl to lead warm-ups?

7:4

Step-by-step explanation:

Reducing the numbers down completely will get you 7:4. For every 7 boys that get picked, 4 girls will get picked.

55% are girls and 45% are boys : ) hope this

step-by-step explanation:

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.
