Semi-Colon “;”

Connects 2 independent clauses

Linked 2 related complete sentences

Breaking down inside of a list

Colon “:”

Focuses on what’s upcoming

Introducing a list

Connects a general statement to a specific explanation

Mean

Sum of set of numbers divided by the numbers in the set.

Median

The middle number when data arranged from least to greatest.

Mode

The number that occurs most often

Range

Difference between the highest and lowest.

Standard Deviation

Standard deviation measures how close things r to the eye

Long vs Small Stdv

Small is very tall and slim, a large is much more widespread and short. Lets say tall looks like Captain clark and large is the blob from hivmind.

Left/Negative Skewed

• Mean < Median < Mode.

• small valiues to a hill on the rirght

Right/Positive Skewed

• Mode < Median < Mean.

• The long tail extends to the right (toward higher values).

Whats greater in a symmetric? Mean or Median?

None =

To that end,

1. "to achieve that goal." Signals the next sentence explains an action taken to accomplish something just mentioned.

Granted,

1. "I admit this is true, but..." Almost always followed by a "however" type contrast later.

That said,

Same idea: "Even given what I just said, here's the other side."

Of course,

1. "Naturally" / "as you'd expect." It signals that what follows is an obvious, unsurprising, or already-expected point — often right before a contrast. 

Again and again,

1. Something happens repeatedly. Signals a pattern or recurring example, not a logical shift.

Indeed,

1. "In fact" / "yes, and even more so." It takes the previous statement and strengthens it, often with a more emphatic or specific version of the same idea. 

That is,

1. "In other words." What follows restates or clarifies the previous point more precisely — not new info, just sharper phrasing.

Hence,

1. "Therefore." Introduces a conclusion or result that logically follows.

Accordingly,

1. Also "therefore/as a result" — one thing happened, so this happened in response.

As such,

1.  "In that capacity" or "therefore" — ties a conclusion back to something's stated nature/identity.

Conversely,

“On the other hand" — introduces an opposite or reversed idea.

Alternatively,

1.  Introduces a different option or possibility, not necessarily opposite, just another path.

What's more,

1. "And in addition to that" — adds a stronger or more surprising point on top of what was said.

Moreover,

1. Same function, adding supporting info — slightly more formal/academic tone than "what's more."

Fittingly

1. Signals that what follows matches or is appropriate given what came before (not a logical result, more like "this makes sense given that").

y = mx +b

slope-intercept form

Ax+By=C

Standard form

y = a(1+r)^t

exponential form

A is the y intercept

ax²+bx+c → b² - 4ac

Discriminant

>0 → two real solutions G2

= 0 → one real solution =1

< 0 → no real solution L0

y = ax²+bx+c

Standard form of a quadratic

x = -b/2a

min or max finder

y = a(x-h)²+k

vertex form

y = a(x - p)(x - q)

factored form of a quadratic

-b/a & c/a

sum & product of a quadraticA

Adjacent to left/oppo = Adjacent to right/oppo

Agnel bisector theorem

SA of a Cube

6s²

SA of a Rectangle

SA = 2(lw + lh+ wh)

SA of Sphere

SA = 4πr²

SA of Cylinder

2πr²+2πrh

SA of Cone

SA = πr²+πrl (L is slant height)

l = sqrt of (r²+h²)

SA of Pyramid

Base Area + (perimeter of base x slant height) /2

Radius on desmos

distance (a,b) /2

Geom Ratios

Square ratio → square it → SA

Cubic ratio → cube it → volume
