Answer:

Final mean value = 24.

Mean value decreased by 6 finally.

Step-by-step explanation:

Total number of restaurant initially = 4

Mean number of tables in restaurants = 30

So, total number of tables in restaurants = 4×30 = 120

Now,

He buys 2 new restaurants with 15 tables and 9 tables .

So, final number of tables = 120 + 15 + 9 = 144.

And, final number of restaurants = 4 initially + 2 newly added = 6 restaurants.

Thus , final mean value of tables in restaurants = \frac{144}{6} = 24.

Thus , mean value decreased by 6 finally

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.

Draw a line having a slope of 1/3 and y-intercept of -1
Lilit [14]
Equation for slope=1/3 and y-intercept=-1 is:
y = mx + b
where m is slope and b is y-intercept.
So, equation becomes
y = -1x + 1/3
Now put different values of x in the equation to get corresponding value of y.
x          y
0         1/3
1        -2/3
2        -5/3
3        -8/3
-1       4/3
-2       7/3
-3       10/3
