Given -
Mean 
= 53 minutes
Standard deviation ( s ) = 53.9 minutes
n = 1010

Answer:
one solution
Step-by-step explanation:
y=-3x+5
y=1/2x-2
You can tell straight off the bat, it does have a solution, and it isn't infinite solutions. If it had no solution, it would have the same slope but different y-intercepts. If it had infinite solutions, the 2 equations would have to be the exact same. So there is only one solution.
