Quadratics

100

What is the difference between linear and quadratic?

Quadratics involve an exponent of 2 at most.

200

What is the Zero of a Function?

The X-intercepts

300

What is another way of saying slope?

Average Rate of Change.

400

What is the method used for converting from standard form to vertex?

Completing the Square.

500

What is the Quadratic Formula?

𝑥 =−𝑏 ±√(𝑏²−4⁢𝑎⁢𝑐)/(2⁢𝑎)

Probability

100

What is the difference between dependent and independent events?

Dependent change each other's outcomes, while independent don't affect each other at all.

200

What are some properties of a Binomial Probability?

Fixed #

2 clearly defined outcomes, at least one being a success

Independent

% chance of success is the same

300

What is the difference between a combination and a permutation?

With a permutation, the order matters. Combinations don't have that.

400

How do you find expected value?

Multiply the sum of the outcomes by the probability of the chosen outcome.

500

How do you determine if something is dependent or not?

Get the probability of something happening, and the probability of something happening given something else occurring. If they aren't equal, they are dependent.
