Answer: 15,120

Step-by-step explanation:

The number of permutations of n objects taken r at one time ^nP_r is calculated by the following formula:

^nP_r=\frac{n!}{(n-r)!}

Now, the given  expression is ^9P_5

by using the above formula , we get

^9P_5=\frac{9!}{(9-5)!}\\\\=\frac{9!}{4!}\\\\=\frac{9\times8\times7\times6\times5\times4!}{4!}\\\\=9\times8\times7\times6\times5=15120

Hence, ^9P_5=15,120

Let the average profit or loss in year 2006 be x millions, 


The average profit for the 8-year period, is the total sum of the profits (or losses) of each year, divided by 8:

so we have:

\displaystyle{ \frac{3.40+2.10+x+0.60+2.10+0.20+1.30+0.75}{8}=1

\displaystyle{\frac{10.45+x}{8}=1

10.45+x=8

x=8-10.45=-2.45


Answer: the loss in 2006, was 2.45 million dollars
