A) z value = (x - π) / <span>σ = 100 - 133 / 23 = -1.43
p(<= 100) = 0.0764
</span>
Im pretty sure that it would be 600%. If it was 600% that would be 600 over 100 which would be 6
The value of m is -30 because once you get m on the one side the equation is 3m=-90 and once you divide -90 by 3 you get m=-30.
