Anational restaurant chain claims that their servers make an average of $12.85 in tips per hour, with a standard deviation of $2.15. the servers at the restaurant chain's location in dallas make an average of $8.65 in tips per hour. given that the data is approximately normal, find the probability that a server, chosen at random, will make more than $8.65 in tips per hour.

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

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.
