Furthermore, the regression formula has been calculated as:

$Y=a+b_1{x}_1+b_2{x}_2+b_3{x}_3$

where $,Y=$ number of automobile accidents

$a=7\mathrm{.}2$

$b_1=3\mathrm{.}5$

$b_2=4\mathrm{.}5$

$b_3=2\mathrm{.}5$

For the given values of $x_1,x_2,$ and $x_3,$ the expected number of accidents will be $($round your responses to one decimal place$)$:

$\backslash$table$[[x_1,x_2,x_3,$# of accidents$],[6\mathrm{.}0,3\mathrm{.}0,0\mathrm{.}0,]]$
