Using data in the table below, construct a Neural Network with one Output Layer $($z$)$ and

one Hidden Layer $($A and B$).(20$ points$)$

a$.$ Calculate the predicted outcome if the inputs to the input nodes are $($x$=1,$ Node $1=\mathrm{.}4,$

Node $2=\mathrm{.}7$ Node $3=\mathrm{.}7$ and Node $4=\mathrm{.}2).$

b$.$ Adjust the weight if the actual output is $0\mathrm{.}750$
