The average r. of c. of a function f(x) on an interval [a,b] is:

  f(b) - f(a)
--------------
    b-a

You'll need to apply this to all four of the given functions.

First function:  f(x) = x^2 + 3x
a= -2; b= 3

Then the ave. r. of c. for this function on this interval is:

    18  - (-2)            20
------------------ = ---------- = 4.  y increases by 4 for every unit increase in x.
      3-(-2)                5

Do the same thing for the other 3 functions.

Then arrange your four results in descending order (greatest to least).

Suppose that the expected number of accidents per week at an industrial plant is 5. Suppose also that the number of workers inju
Ksivusya [100]

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.
