Answer: The solution to a system of linear equations is the point at which the lines representing the linear equations intersect. Two lines in the x y xy xy -plane can intersect once, never intersect, or completely overlap.

Answer:
The answer is 0.9599.
Explanation:
mu (sample) = mu = 8.4
s.d. (sample) = 1.8/ sq. rt. 40
P( greater than 8.1) = (8.9-8.4)/(1.8/ sq. rt. 40)
Let x be the mean time for the 40 mechanics
Standardize the mechanics: (8.9-8.4)/(1.8/ sq. rt. 40) = 1.75 = Z
P( x > 8.9) = P(Z > 1.75), this means the area to the right of Z = 1.75.
Then you need to look in the table of the Normal distribution, Z(1.75) =0.9599
