How many ways exist to group n ordered elements?Your approach does indeed have $2^n-1$ groupings, because there are $n-1$ possible places to insert a vertical spacer, and each of these may be done, or not, independently.Your approach does not include the possibility that we draw the two strokes for "" nonconsecutively. To count those, we need Bell numbers

Do roasted and unroasted peppers taste different after slow cooking in soup all day?
The roasting process doesn't just heat the peppers, but the high, dry heat also causes a bit of both scorching and carmelization of the sugars, so I would expect there to be a bit of different flavor, even if both get cooked to the same consistency in a subsequent process

Standard deviation / Bell Shaped Distribution
Hint: Have you tried using the 68/95/99.7 rule? 9 inches greater than the mean is 2 standard deviations. The question is asking for the area to the right of $2 sigma$. Since the interval within $2sigma$ from the mean is 95%, the left and right combined is 5%, so the area only to the right is 2.
5%.

I think one of my students may have an emotional problem?
Since you teach in a high school, I highly recommend that you pass this information on to a counselor or school psychologist. They may already have confidential information that you are not aware of, or at least can advise you of a possible next step. Your instincts may be correct.

Is this property of the Bell's number evident?
This follows from the well-known Touchard's congruence (here for a random reference). Following your notation, the congruence is:$$B(np^k)equiv kB(n)B(n1) mod p$$Taking $n0$:$$B(p^k)equiv kB(0)B(1) mod p$$And since $B(0)B(1)1$,$$B(p^k)equiv k1 mod p$$

Your parallel is slightly off. It's not Biko that Wikus is related to but Biko's friend, Donald Woods from "Cry Freedom".Both Wikus and Woods were initially of the governing race, and both started with adversarial relationship to Biko/alien known as Christopher Johnson, only later to turn into friends

What did The Ring (, Ringu) in the original Japanese version refer to?
I read somewhere (how many times have we seen that?) that the author chose the word Ringu from the English word ring because it has a double meaning. A circular shape ... or the alarm made by a telephone.The title for Ringu used in Spanish-speaking countries is El crculo

Has anyone come across a geometric interpretation for fractional exponents of pi?
To generalize Professor Vector's comment, the $d$-dimensional hypersphere of radius 1 has hypervolume $A_dpi^s$ for some easily computed rational constant $A_d$, where $s$ is the integer part of $d/2$ see Wikipedia. Then the hypercube with the same hypervolume has side $A_d^1/dpi^s/d$

Single word to describe something that should have been done at the beginning
I think the suggestions above are excellent, but since it is important that the accessibility be a part of the design, it really calls for an altered sentence structure.Accessibility remediation after the fact is harder. Accessibility should be a design parameter from the start (or "at the conceptual stage").

Disable beeping in lightdm
One solution is to turn off the beep with xset b off. This can be made to take effect for the lightdm greeter by adding it to the greeter-setup-script line of the lightdm.conf file at /etc/lightdm/lightdm.conf. The config line would then be: greeter-setup-scriptxset b off.

PRNG for a gaussian distribution?
You can generate any distribution by using a standard PRNG to choose $X$ uniformly from the interval $0,1$ and then returning $F^-1(X)$, where $F$ is the cumulative distribution function of the distribution you're interested in.For the Gaussian distribution, though, it's usually better to use BoxMuller or ziggurat

How can I disable bells/visualbells in vim?
To disable the bell altogether, you need to(This is explained in the documentation of 'visualbell', but not very clearly.) Even with novisualbell, you might see a visual bell if vim emits a bell control sequence (usually a) and the terminal is configured to flash rather than make a sound

How to approximate decaying probability distributions with few dice?
Use integer division; that is, division where you keep only the whole number part.
For example, d6/d6 or d10/d10https://anydice.com/program/1a38f
Those are quite easy to calculate, or, since the outcome is very limited, you can just print a cheat sheet with the results.

GetCount not implemented on 4.4?

Do helmets go out of style and get discontinued by manufacturers?
Depending on how long it takes before you change helmets, possibly not. My understanding is that even just lying around, the crash-resistant foam in helmets gradually degrades. Five years seems to be a common number, but I don't see any supporting evidence, so take that for the little it's worth.

How do I ensure an appropriate payout ratio for a slot machine?
The easier and more reliable way to do this is not by simulating reels but rather have an internal die that chooses what the player wins and then just populate the reel procedurally(or have a large set of them saved somewhere but that will probably take longer to make)

I'd recommend Smoothwall, which can handle reporting (through log files and/or its Web GUI) the sites visited and who visited them. Add on the bandwidthd plugin, and you can see what machine(s) is(are) using the most bandwidth, and what protocol they're using (HTTP, FTP, P2P, etc.)

Four cups on a table
This solution is incorrect because it doesn't account for case 2b since flipping two diagonals of 2b causes it to remain the same orientation.Therefore step 2 is an invalid assumption since the majority orientation is not the only possible outcome.Solution is 6 steps.This now takes into account case 2b

Is there a technique for turning an image into a 2d model?
You could have done that with OpenSCAD, there are instructions for extruding. Personally, I'd just do a 1 altitude copy with
Image 2 STL 2 Heightmap Mesh Converter Generator, then rotate in OpenSCAD. It's called rotate_extrude() and is used for seashells.In MeshLab you can use Laplacian Smooth to depixelate/antialias it.

How to disable system beep for non-privileged user
For beeps generated in your shell (which seem to be the most annoying ones), add this to "/.inputrc":Note that this is not terminal- but host-specific. That means that when you log in to another computer via ssh where this isn't set, the beep is back. (I tested on Fedora).

What kind of bigram probability smoothing is this?
This looks like it might be implementing Laplace smoothing (though I can't explain the extra 2 in the first two calculations).There are many smoothing methods, e.g., Lidstone, Good-Turing, Kneser-Tey, Witten-Bell. You can also use interpolation and backoff to handle rare or low-probability events when computing conditional probabilities like this.

Can you change the skill auto battle uses?
Currently, no. Auto battle favors skill use over regular attacking. That said, it tries to be smart about the skill use. For Example, if your party is at good health, your healer won't use healing. Or if there is only one enemy, your unit likely won't use the aoe skill

When the render job is complete, a bell rings.

Bell measurement and relativity of simultaneity
Measurement doesn't entangle the particles, they're already entangled. Measurement does destroy entanglement though. So measurements would need to be simultaneous for the correlation to manifest itself. If measurements are taken in succession, the latter measurement wouldn't be on an entangled system. I'm not sure what your second question is asking

What references should be cited to support using 30 as a large enough sample size?
IMO, it all depends on what you want to use your sample for. Two "silly" examples to illustrate what I mean: If you need to estimate a mean, 30 observations is more than enough. If you need to estimate a linear regression with 100 predictors, 30 observations will not be close to enough.

Router in front of Bell modem drops out TV
The traffic is separated onto virtual LANs (VLAN), internet traffic is on VLAN 35 and Bell Fibe TV traffic is on VLAN 36. The Bell router handles this while the stock D-LINK DIR-815 doesn't. Set things up so TV traffic doesn't have to go through the DLINK and it should be fine.
