The night watchman in a factory cannot guard both the safe in back and the cash register in front. The safe contains $6000, whil

Zolol [24]

Answer:

The guard should be positioned at the safe

Step-by-step explanation:

The night watchmen should be positioned to guard whichever place gives the highest expected value to the thief.

The expected value of robbing the safe is:

$EV_{s} = \$ 6000*0.2\\EV_{s} = \$ 1200$

The expected value of robbing the cash register is:

$EV_{r} = \$ 1000*0.8\\EV_{r} = \$ 800$

Therefore, the guard should be positioned at the safe since it yields a higher expected value to the thief in case he tries to rob it.

Your answer should be a polynomial in standard form. ( − 2 h + 9 ) ( 9 h − 2 ) = (−2h+9)(9h−2)=

AleksandrR [38]

Answer:

$-18\cdot h^{2} + 85\cdot h - 18$

Step-by-step explanation:

The polynomial in standard form is:

$(-2\cdot h + 9) \cdot (9\cdot h - 2)$

$-18\cdot h^{2} + 81\cdot h +4 \cdot h - 18$

$-18\cdot h^{2} + 85\cdot h - 18$
