I'm one hundred students taking a statistics test were randomly assigned to two equal groups. each student in group a was given an apple as a snack during a test; each student in group b was given a banana. the mean test result of group a was 7 points higher than that of group b.

y > 1/3x

y < = -x + 4

hope this : )

i believe the correct answer is b.

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

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.
