The number of peanuts in bags is normally distributed with a mean of 184.7 peanuts
and a standard deviation of 3.3 peanuts.
what is the z-score of a bag containing 178 peanuts?

X= 49; x = 4step 1: foilstep 2: equal both to 0step 3: find x individually

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0
