z-score = 4.43,

It is a Good day

Step-by-step explanation:

The provided information is:

Mean = $28,286.28

Standard deviation = $1,500

X+y+z=1<br> X-2y+3z=2<br> X+z-5=0

serious [3.7K]

x+y+z=1

x=1/(y+z)

1/(y+z)-2y+3z=2

1-2y²-2yz+3yz+3z²=2(y+z)

(1-2y²+yz+3z²)/2=y+z

z=(1-2y²+yz+3z²)/2 -y/1

z=(1-2y²+yz+3z²-2y)/2
