Notes > Expect an LR and WB for each lecture. WBs target 15-minute engagements (longer early on); LRs are short, ~5 minutes. > > - 🎯 **[LR] [Day 14 Reflection Questions](https://elearning.mines.edu/courses/81632/quizzes/121452)** — 4 questions drawn from Monday's material, unlimited attempts, highest kept — due **Wednesday 9/30, 11:59pm** > - 🎯 **[LR] [Day 14 Reflection Statement](https://elearning.mines.edu/courses/81632/quizzes/121453)** — one free response, no wrong answers — due **Wednesday 9/30, 11:59pm** > - 🎯 **[WB] [Workbook 10](https://elearning.mines.edu/courses/81632/assignments/587683)** · [[MATH310F26_WB10.pdf|blank]] · [[MATH310F26(Workbook 10 Companion) - Reading a sound's fingerprint|companion]] — due **today, Wednesday 9/30, 11:59pm** > - **Workbook check-in: Workbooks 1–10 due today, Wednesday 9/30** (soft); in-person checks begin soon > - **Modeling-project**: responses to your problem statements were promised before today; this week, a preliminary estimate of your problem's symbols, equations, and mathematics > - **Presentations**: the packaged mock presentations (TA's Connections story + the instructor's), timing TBA > - 🎬 [[MATH310F26 - Random numbers, two videos]] — the guided videos for this unit, if you haven't yet > [!example]- 🗃️ COMAP Corner — three from the archive > *TK — three picks (one stat, one computational, one weird) from the catalog land here.* > [!warning] Skeleton — this is the pre-class page > Day 15 has not met yet (title provisional). Monday ended with the first moment of a step, $\mathbb{E}[X]=L_{1}+p_{2}(L_{2}-L_{1})$, and the promise: next, the **second moment** — the variance of a step — and then both moments applied to the walkers $S_{n}=S_{0}+\sum X_{i}$ to say where they should end up in aggregate: the $\sqrt{n}$ bands on the [[MATH310F26(Day 14) - Into stochasticity|dice-walk figures]] "that we can actually derive," the 99.7% zone, and where the central limit theorem lives in it. The transcript and any captures fill in after Wednesday's class.
