comment Calculating expected value from paired values and weights
+1 Nice, clear explanation.

Very good point.

+1 Interesting use of Dot. It would be nice if you provided an explanation of the code.

Thanks for pointing this out.

comment Finding all shortest paths between two vertices
It should work with weighted edges. From the documentation on GraphDistance: "For a weighted graph, the distance is the minimum of the sum of weights along any path between s and t."

comment Is there a nice way to display big nested tables?
I don't see any nesting in your table. It looks like a simple table of graphs with an ID and what appears to be an average value. Are you seriously planning to show each of these graphs to your audience without putting them to sleep?

comment How convert list of numbers to list of points on x-axis?
You may easily combine Plot and NumberLinePlot. For example, Show[{ Plot[2 Sin[x] + x, {x, 0, 15}], NumberLinePlot[{2, 4, 7, 10, 13, 6}, Spacings -> 0]}]

comment InfiniteLine Woes
@MarcoB, That's just what tripped me up. And I was in an unusual hurry too.

comment InfiniteLine Woes
Thanks. The syntax even matches that of Line. I'm surprised I didn't try it.

What about this? (from the documentation) Graphics[InfiniteLine[{0, 0}, {1, 1}], Frame -> True]

ImageCorners reference.wolfram.com/language/ref/ImageCorners.html may be useful for step 1.

comment Pull out scaling factor from a denominator
Algohi, That seems to be a general solution to the problem.

Algohi, try ((2 + x)/7)[[2]]

comment VertexLabels, EdgeLabels and the direction of the arrows on a directed graph
You should be able to find solutions to all of your problems by consulting the documentation. See GraphicsGrid,VertexCoordinates, EdgeStyle, etc...

comment Font presentation difference between version 9 and version 10
Looks fine on my MacBook with Mathematica v. 10.0.2 The font is heavier than your upper image, but far smoother than your lower image. Shouldn't Georgia be a serif font? Your lower image is sans serif.

comment Dynamically Update both a HorizontalGauge range and the value
This seems to offer more general solution (which is great because I want to add additional scales), but the lower marker sometimes jambs, sitting immobile while the upper marker is being dragged.

comment Fine precision control in IntervalSlider
Basically, I want students to be able to explore a number line by zooming in or out at will. I plan to have multiple Horizontal Gauges on display at once. But I am still thinking about the functionality, the operations I want students to be able to apply.

Good point. I hadn't tried adjusting the interval size!

comment What is Association[Rule[“ID”,number ] and how it is used
I'm puzzled. Look at TreeForm[ds1] and then ds1[[1]]. How can you get the full list of data out of the dataset?
