Answer:
2,520
Step-by-step explanation:
The number of possible arrangements of officers patrolling the streets is the combination of choosing 5 officers out of 10 (₁₀C₅). After choosing the patrolling officers, the number of arrangements for the officers working full time at the station is given by the combination of choosing 2 officers out of the 5 remaining (₅C₂). The remaining officers should be on reserve at the station (₃C₃). The total number of arrangements is:
![N = _{10}C_5*_5C_2*_3C_3\\N=\frac{10!}{(10-5)!5!} *\frac{5!}{(5-2)!2!}*\frac{3!}{(3-3)!3!} \\N=2,520](https://tex.z-dn.net/?f=N%20%3D%20_%7B10%7DC_5%2A_5C_2%2A_3C_3%5C%5CN%3D%5Cfrac%7B10%21%7D%7B%2810-5%29%215%21%7D%20%2A%5Cfrac%7B5%21%7D%7B%285-2%29%212%21%7D%2A%5Cfrac%7B3%21%7D%7B%283-3%29%213%21%7D%20%5C%5CN%3D2%2C520)

Solve for x.
![16:1.5=20:x](https://tex.z-dn.net/?f=16%3A1.5%3D20%3Ax)
![16/1.5=20/x](https://tex.z-dn.net/?f=16%2F1.5%3D20%2Fx)
Cross Multiply.
![16*x=20*1.5](https://tex.z-dn.net/?f=16%2Ax%3D20%2A1.5)
Simplify.
![16x=30](https://tex.z-dn.net/?f=16x%3D30)
Divide both sides by
16.
![(16x)/16=(30)/16](https://tex.z-dn.net/?f=%2816x%29%2F16%3D%2830%29%2F16)
Simplify.
