algebra 2 final notecard (featuring coinpin)

unfortunately getting tossed after the final so gotta preserve it while i can 💔

lil mistake—if the discriminant is < 0, it has two imaginary solutions! but if it asks for only real solutions, there are zero real solutions (note to self)

@ghostyghost202 i loved your coinpin doodles so much i was like, i gotta take this with me somehow. tysm your art is literally sacred to me

also asymptote reference? (those who know)

missed opportunity to put four and x on there i feel like they would love this. but i need coinpin to get through this final 🙏

thankfully it's. all multiple-choice

🧠 Top 10 Statistics Formulas Every Data Analyst Should Know

Why These Formulas Matter Statistics is the foundation of data science, analytics, research, and decision-making. These formulas help you:

Understand and summarize data

Identify patterns and trends

Test hypotheses and assumptions

Communicate insights clearly

Let’s explore the top 10 formulas you must know.

1. Mean (Average)

Formula: Mean = (x₁ + x₂ + ... + xₙ) / n

Explanation: The central value of a dataset — helps in understanding the overall trend.

2. Standard Deviation (σ)

Formula: σ = √[Σ(xᵢ - μ)² / n]

Explanation: Shows how spread out the numbers are from the mean — key for variability.

3. Variance (σ²)

Formula: σ² = Σ(xᵢ - μ)² / n

Explanation: The square of standard deviation — useful in model evaluation and statistics.

4. Probability (P)

Formula: P(A) = Number of favorable outcomes / Total outcomes

Explanation: Core of inferential statistics — used in predictions and risk assessment.

5. Bayes’ Theorem

Formula: P(A|B) = [P(B|A) × P(A)] / P(B)

Explanation: Calculates conditional probability — widely used in ML and diagnostics.

6. Z-Score

Formula: z = (x - μ) / σ

Explanation: Tells how many standard deviations a point is from the mean — useful for anomaly detection.

7. Confidence Interval (CI)

Formula: CI = x̄ ± Z*(σ/√n)

Explanation: Gives a range that likely contains the true population mean — essential for surveys.

8. p-value

Formula: Depends on test statistic (e.g., t or z distribution)

Explanation: Tells the probability of observing results under the null hypothesis — core for significance testing.

9. t-Test Statistic

Formula: t = (x̄₁ - x̄₂) / √[(s₁²/n₁) + (s₂²/n₂)]

Explanation: Used to compare means between two groups — key in A/B testing.

10. Pearson’s Correlation Coefficient (r)

Formula: r = Σ[(x - x̄)(y - ȳ)] / √[Σ(x - x̄)² × Σ(y - ȳ)²]

Explanation: Measures the strength and direction of a linear relationship between two variables.

Final Thoughts These formulas are the backbone of statistical reasoning and data analysis. Whether you’re exploring customer trends, testing experiments, or interpreting research — they’re must-haves.

Did I find a book with all formulas in math, physics and chemistry?

Of course I did.

Did I find in German language?

Of course.

Do I know any word in German language?

Nope, but I still buy it.

We’re all animals who need enrichment in our cages. Sometimes that enrichment is making art or destroying something.

Sometimes it’s figuring out how Google sheets macro coding works so you can build a little program for your brother to enter in his win/loss ratio for Balatro, broken down by Stake & Deck.

Let me know if you want a copy of the file for whatever reason. It’s fun :) and I’m happy to make changes for you.

Tumblr-friendly text & cleaned up macro code & expanded Sheets formulas at bottom of the readmore & explanations if you’re interested.

I know it’s not optimized or whatever but I’m new to JavaScript and I’m used to using Excel instead of Google sheets.

Google Sheets Macro aka Google Apps Script aka JavaScript:

What that code would look like with and without variables :(

Google Sheets in cell formulas:

(I know they look ridiculous)

+ expanded view so it’s a little easier to follow

(Color-coded in-line text Tumblr-friendly version in Pic 4 ID below.)

+ explanations!

Google Sheets Macro AKA JavaScript Coding

[Picture 1 Text ID]

Macro Code Text: Comments are in blue.

function sendQuote() { //Function named sendQuote

//Set Variables

var ui = SpreadsheetApp.getUi();

var Deck = ui.prompt("Deck Type").getResponseText(); //prompt

var Stake = ui.prompt("Stake Level").getResponseText(); //prompt

var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();

var sheetSub = spreadsheet.getSheetByName("Submission & Dashboard");

var sheetEntry = spreadsheet.getSheetByName("List of Game Entries");

const WinLose = ui.alert("Did you win?", ui.ButtonSet.YES_NO); //prompt

//Check WinLose condition

if (WinLose === ui.Button.YES) {

var WinLoseNum = 1;

var WinLoseVar = 'Win';

ui.alert('Yay!');

}

else {

var WinLoseNum = 0;

var WinLoseVar = 'Loss';

ui.alert('Loser.');

}

//Check if correct info

const response = ui.alert("Is this info correct?\nDeck Type: "+ Deck + "\nStake Level: " + Stake + "\nResult: " + WinLoseVar, ui.ButtonSet.YES_NO );

//Could have probably done "Is this info correct?\nDeckType: ${Deck}\nStake Level: ${Stake}\nResult: ${WinLoseVar}"

//Set Cell Variables

var cellValue = sheetSub.getRange("B3").getValue(); //gives max # of current Responses

var Row = cellValue + 5; //Gives next available line row

if (response === ui.Button.YES) { //If info is correct, do this

var Comments = ui.prompt("Add any run notes here.").getResponseText();

ui.alert("Response Submitted");

//Fill Table Values

sheetEntry.getRange("B"+ Row).setValue(cellValue + 1);

sheetEntry.getRange("C"+ Row).setValue(Deck);

sheetEntry.getRange("D"+ Row).setValue(Stake);

sheetEntry.getRange("E"+ Row).setValue(WinLoseNum);

sheetEntry.getRange("F"+ Row).setValue(Comments);

}

else { //If info is not correct, exit & try again

ui.alert("Try Again!");

}

}

Google Apps Script is based on JavaScript so it’s easiest to look up 'how to do x in JavaScript' than google sheets.

Functions Used

getUi()

prompt(string)

getResponseText()

getActiveSpreadsheet()

getSheetByName(string)

alert(string, ButtonSet)

getRange()

getValue()

setValue(variable)

If() {}

Else {}

//let - can't be redefined in scope

//var - value can change in scope

//const - value can't be changed

You can make your own functions to make your code more readable:

function repeatBack () {

var ui = SpreadsheetApp.getUi();

var = wordsPlease = ui.prompt("What would you like me to say?").getResponseText();

sayTo(wordsPlease);

}

function sayTo (wordsToSayBack) {

ui.alert(wordsToSayBack);

}

Haven't tested this one yet:

function sayHello(name = "Guest") {

console.log(`Hello, ${name}!`);

}

sayHello(); // Output: "Hello, Guest!"

sayHello("Bob"); // Output: "Hello, Bob!"

How Macro Coding Functions Work

Functions using '.' in them act like location pointers.

var ui = SpreadsheetApp.getUi(); //Google Sheets UI

var spreadsheet = SpreadsheetApp.getActiveSpreadsheet(); //Google Sheets UI -> Active Spreadsheet

var sheetEntry = spreadsheet.getSheetByName("List of Game Entries"); //Google Sheets UI -> Active Spreadsheet -> Sheet Named "List of Game Entries"

var sheetSub = spreadsheet.getSheetByName("Submission & Dashboard"); //Google Sheets UI -> Active Spreadsheet -> Sheet Named "Submission & Dashboard"

var cellValue = sheetSub.getRange("B3").getValue(); // Sheet Named "Submission & Dashboard" -> Cell Range (B3) -> Get Value

var Row = cellValue + 5; //B3 Value + 5

var Deck = ui.prompt("Deck Type").getResponseText(); //Google Sheets UI -> Prompt Function Class (Deck Type) -> Get Response Text

With Variables:

sheetEntry.getRange("B"+ Row).setValue(cellValue + 1); //Set next entry in column B to 'Row + 1 '

sheetEntry.getRange("C"+ Row).setValue(Deck); //Set next entry in column C to 'Deck'

Without Variables:

SpreadsheetApp.getActiveSpreadsheet().getSheetByName("List of Game Entries").getRange("B"+ cellValue + 5).setValue( SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Submission & Dashboard").getRange("B3").getValue() + 1);

SpreadsheetApp.getActiveSpreadsheet().getSheetByName("List of Game Entries").getRange("B"+ cellValue + 5).setValue(SpreadsheetApp.getUi().prompt("Deck Type").getResponseText());

$A$1 - use to freeze column or row or both in functions - helpful when function used across a range

$D6 - Deck is all in column D

E$5 - Stake is all in row 5

"Words" & Value & "Words"

Other Options depending on context:

TEXTJOIN(delimiter, Ignore Empty, Text) - Joins with delimiter

TEXTJOIN(", ", TRUE, C1:C6, D2:D9) - This, That, These

CONCAT(Texts) - Joins list of values

CONCATENATE(Texts) - Joins several text strings into 1

So I updated my fanfiction databases like an insane amount since the last time I posted about it it includes having I think two more databases- One for stats and one for reading logs because I want to be able to more accurately say when I'm reading and how much I'm reading at a time because I read a lot of wips--

but the stats one is the one that I want to talk about because obviously yeah things are based on statistics and therefore averages and medians and whatever. But it's crazy to me that I gave right a formula that's like hey, this fic is about 12,644 words-- It'll probably take you 33 minutes to read it. And then I'll be exactly right! Like yeah obviously it's math apparently at my like average reading speed is around 385-390 wpm but I have the like estimated page numbers in my database which is just actually complete bull because it's me trying to estimate how many words are on a page but like sometimes a page has more dialogue. Sometimes I'm reading a text fic that'll be like insanely longer technically because there's so few words on each page but I can't really account for that in the formula-- that is not the case with words per minute because that is like straight data and every single reading log that I create adds to the data so it just gets more accurate the more I read!

life update, wtf is ableton this is where im at rn

fukit only deeper rn

incorporating the KS sampler into my workflow, as a standalone PC application realy increases productivity. i like how it can auto chop samples into 1,2,3,4,5,6,7,8,9,10.11.12.13.14.15.16 or more individual chops and is very accurate and eliminates all the additional guesswork that i would need to face with EDISON. chopped a sample and imported th3 chops inro MPC ....

in short KS opened a whole new workflow into my routine and has enhanced my productions ... also watching live underground MPC/SP404 shows lately has sparked my interest for DAW production again and has motivates me to try harder and make more music

Tuesday observation:

Do you see it? It looks like mathematical ghosts. I wanted to look outside through the glass wall, but there are formulas flying in front of my eyes.

The design of the mathematical institute of Orsay makes you see some mathematics in transparent.

I’ve been finding Ohms law a little useful lately so I’ve been playing with some designs inspired by it - If in doubt consult Ohm’s law available with black white and blue text.

Majareta

Mi cordura hace tiempo que ya no sostiene el peso aplastante que me rodea. Hizo alianza con la locura porque necesita refuerzos, tropas aliadas, municiones inconexas, sinapsis de escapatoria que excaven túneles aleatorios, como los algoritmos entrópicos que mueven cada lámpara de lava. Hace meses que se me terminó el año, y no sé como vivir este limbo en el que quedé atrapado, regando todas las semanas plantas que se niegan a conversar conmigo. Por momentos me sorprende la razón. No la mía, la de lxs demás, entra sin avisar, tiene llave propia, un imparable tsunami de sentido común con fórmulas, usos, costumbres y soluciones infalibles para vidas prefabricadas. Les respondo que no hay repuestos para lo que se me rompió, no escuchan e insisten en venderme sus piezas. “Son universales” afirman lxs vendedorxs “sirven para todxs, también para vos”. Ya compré cuando era más ingenuo que loco y me cagaron (es más fácil engañar a la inocencia que a la incoherencia), así llegué a este punto, por usar componentes de otras vidas que no fueron pensados para la mía. Fue entonces cuando decidí trepar a la luna usando sus rayos como cuerda. Allá arriba encontré vodka, hielo para congelar mis ideas y fuego para incinerar mi contaminación de coherencia, pesa un montón y no me sirve para nada más que para caminar más lento mientras me susurra direcciones de lugares que no me abren las puertas. Hoy evito las horas en que los girasoles se mueven, me pregunto qué ofendió a las plantas, meo con viento a favor, cago en los baños de humildad, nado en la nada, busco motivaciones mudas (sin frases), y sobre todo jamás (JAMÁS) veo señales en ningún lado. Si encuentro alguna coincidencia con el universo, discrepo. El problema de la locura no es la locura, es a donde apunta. Por eso ahora entro por las ventanas y sigo únicamente la dirección de brújulas rotas.
