It amazes me how many people in manufacturing don't understand the basic concepts of Statistic Process Control.
Sorry, not math questions here. I prefer statistics, charts and seeking out the economic threshold, but I too am bored.
I also can't sleep and have a headache.
Math has apparently been your friend for a long time.

If it takes a city's public works employee 60 seconds to dig a one cubic foot hole on the ground, 30 seconds for two employees to dig the same hole, and 20 seconds for three employees, how much time will it take for a 60 man brigade to accomplish the same task?

It takes 24 black guys and one white guy to close the flood gates in St. Louis along the Mississippi River. The endloader does all the work.

Here is another one.
Find the two optimal values of x, f(x), and state whether each optimal point is a minimum or a maximum.
y=f(x)=x3-5x2-50x+1000first one, a minimum at -2.5
second one, a minimum at -13.66, a maximum at 3.660 -

she comes back later and says, here's a buck back. you paid 9.
so, all three of you guys put together paid 27, and she's still got 2, which adds up to 29.
how's that possible?!? that's the problem. where's the extra dollar??okay, I went and googled the answer. yes, they paid 27 bucks, but the total doesn't have to be 30. they paid 27 bucks: 25 to the landlord, and 2 to the girl. aarrgh.0 -

OK here's one.
I have 67 dollars. How many bags minimum will it take if you put any amount into each bag to come up with every possible combination of money(in whole dollars)and just handed me any combination of bags for any amount I asked for.
Example: if I asked for $11 and you had 1 bag with $5 and one with $6 you would hand me 2 bags and not just $11. So how many bags would it take minimum to come up with any combination up to $67?[?]
Have fun.0 -
OH I wount be here for a couple days so be patient. But it's not that hard. 0 -

Have fun.I'll take the approach that any number could be a sum of prime numbers, so that should minimize the number of bags I have laying around to use.
the prime numbers up to 67 are:
1$
2$
3$
5$
7$
11$
13$
17$
19$
23$
29$
31$
37$
41$
43$
47$
53$
57$
61$
67$
so, that's the shortest list of bags I could use for any combination up to 67$.
I think any amount you ask for needs only 2 bags.

Nope not even close.[:D]You can give me any number of bags to come up with the amout. But what is the minimum number of bags to come up with any combination to make $67? 0 -
"So how many bags would it take minimum to come up with any combination up to $67?"
there are 20 bags on the list, they can be used to give you any amount up to 67$, and the list can't be any shorter. so... 20 is the minimum! and there they are.0 -
Man, I haven't used any of my Calc or Trig since College.[:(] I can't even remember it. Guess I need to get out the ole textbook and run through it again. 0 -

There's still a dollar missing somewhere...they paid out $30 to begin with...0 -

The minimum amout of bags you could use is one. All 67 dollars in one bag.0 -

Sorry busch for giving you such a hard one to start with. Now I believe in the tv show, are you smarter than a 5th grader because that is the grade where I was taught the formula to solve this problem.
Thank you for your worthy time in trying to solve this problem, but your not even close yet. Keep trying, I think that you can do it.0 -

In that case the answer is 2. 34 dollors in one bag and 33 in the other bag.0 -

Nothing missing Eric, the three brothers each got back $1, for a total of $3. That leaves $27 paid out, $25 of which went to the landlord, and $2 that was kept by the sister.[:)]0 -
