Answer:
12.5
Step-by-step explanation:
If the number of workers injured in each accident is i<em>ndependent </em>of the number of accidents that occur, <em>then the expected number of workers injured in a week equals the expected number of accidents per week times the expected number of workers injured in each accident.
</em>
But the expected number of workers injured in each accident is precisely the average or mean, so
<em>Expected number of workers injured in a week = 5*2.5 = 12.5.
</em>
Or in other words, in 10 weeks there will probably be 125 workers injured.

Answer:
One equation would be y= -1.5x +11
Step-by-step explanation:
Here's a table to show the coordinates
x: y:
8 -1
-------------------
-4 17
the x coor. 8 goes down by 12 to get to the next x coor. -4.
8-12= -4
the y coor. -1 goes up by 18 to get to the next y coor. 17.
-1+18= 17
therefore 18/-12 is -1.5 which can be your k in y=kx+b.
Check your answer.
-1.5*8= -12 but when you add 11, you get the y coor. -1
Do the same with the other x coor.
-4*-1.5= 6 + 11 =17
11 can be your b in the slope-intercept form equation.
One equation may be y = -1.5x +11
