Answer:

No real solutions.

Step-by-step explanation:

Square both sides:

$x-3=(x-1)^2\\x-3=x^2-2x+1\\x^2-3x+4=0$

Evaluate the discriminant:

$\Delta =3^2-4 \times 1 \times 4$

$= 9-16=-7<0$

Since $\Delta $ is less than zero, there are no real solutions.

The z-score will be given by:
z=(x-μ)/σ
given that:
x=94
μ=mean=84.5
σ=standard deviation=4.4
thus
z=(94-84.5)/4.4
z=2.1591
