The students in a typing class have a mean typing rate of 38.2 words per minute. Five randomly selected students have typing rates of 32, 28, 41, 38, and 45 words per minute. What is the value of μ and x¯ ?

μ = 38.2 wpm, x¯ = 38.0 wpm

μ = 36.8 wpm, x¯ = 38.2 wpm

μ = 38.2 wpm, x¯ = 36.8 wpm

μ = 38.0 wpm, x¯ = 38.2 wpm

µ = 38.2 wpm, = 36.8 wpm

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.
