Convert the decimal number $-4\mathrm{.}375$ to a floating$-$point number expressed in the $14-$bit simple model given in your textbook.

Note: in the $14-$bit simple model, the left$-$most bit is the sign, followed by $5$ bits for the exponent, followed by $8$ bits for the mantissa $($There are no implied bits$).$ The exponent is in Excess $15$ notation.
