<span>simplify third eqn -2x+5y+2x=4
5y=4
y=4/5

substitute back to 1st n 2nd eqn n solve for x n z
-4x-4-z=18 and -2x-4-2z=12
simplify -4x-z=22 and -2x-2z=16
-4x-(-x-8)=22
-3x+8=22
x=-14/3
z=-10/3

kirill115 [55]

The area of the shaded region is 0.1271 (12.71%).

<h3>What is the z score?</h3>

Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = (raw score - mean)/standard deviation

Given:

Mean 0 and standard deviation 1. Hence, for z=-1.14:

P(z < -1.14) = 0.1271

The area of the shaded region is 0.1271 (12.71%).
