Answer:
<u>The correct answer is C. 66.7</u>
Step-by-step explanation:
1. y varies directly with regard to x
y = 9 and x = 24
If y = 25, what is the value of x?
2. For finding that value of x, first of all, we should understand what happened to y.
If y moves from 9 to 25 it means that y has been multiplied by 2.77, using this simple division
25/9 = 2.777
3. And we should use that same number or value to calculate the new value of x
If x was 24, now the new value of x is 24 * 2.777
24 * 2.777 = 66. 67 or 66.7 (rounding to just one decimal)
<u>The correct answer is C. 66.7</u>
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](https://tex.z-dn.net/?f=EV_%7Bs%7D%20%3D%20%5C%24%206000%2A0.2%5C%5CEV_%7Bs%7D%20%3D%20%5C%24%201200)
The expected value of robbing the cash register is:
![EV_{r} = \$ 1000*0.8\\EV_{r} = \$ 800](https://tex.z-dn.net/?f=EV_%7Br%7D%20%3D%20%5C%24%201000%2A0.8%5C%5CEV_%7Br%7D%20%3D%20%5C%24%20800)
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.

denotes the complement of set B, which is the set of all elements that are in the universal set that are not in set B. In this case, this set is ![\{3, 4, 5, 6, 8, 11, 13, 16, 17, 19, 20, 22, 23, 24, 25, 26, 27, 28\}](https://tex.z-dn.net/?f=%5C%7B3%2C%204%2C%205%2C%206%2C%208%2C%2011%2C%2013%2C%2016%2C%2017%2C%2019%2C%2020%2C%2022%2C%2023%2C%2024%2C%2025%2C%2026%2C%2027%2C%2028%5C%7D)
