Statistics
This is a line drawn to approximate the association of data.
What is a line of best fit?
These are two types of functions.
What are arithmetic and geometric?( Linear and exponential)
These are the four methods for solving a system of equations
What are elimination method, substitution method, equal values method, and graphing?
This is what it means to be congruent (complete definition).
What is having the same shape and same size?
Annie's loan charges interest of 5% per year. This is the multiplier.
What is 1.05?
This coefficient is a measure of the strength of the association. Often, it's given the letter "r".
What is the correlation coefficient?
This is the equation of a line parallel to y=4x + 7
What is y = 4x + 1 (or any other starting value)?
A system of equations that make parallel lines will have
(A) No solution (B) One solution, or (C) Infinitely many solutions
What is (A) No solution?
This is either true or false: Triangle FOG is congruent to triangle JKL, so side OG is congruent to side LK.
What is false?
Annie's stock is decreasing at a rate of 15% per year. This is the multiplier to represent this situation.
What is 85%?
A correlation coefficient of -0.1 implies this type of association.
What is a weak negative association?
This is the simplified version of (n2)5
What is n10?
This is the solution to the system y=4x+3 y=-4x+11.
What is (1, 7)?
This type of transformation does not change an object's orientation.
What is translation?
This is what you get when you solve for x.
|x+9|=10
What is x = 1, -19?
Frequency and relative frequency are different in this way.
What is: relative frequency is a percent or ratio, while frequency is a number or count?
This is the simplified version of n3n-2
What is n?
This is a solution to y=3x+4 y=2x-1
What is (-5, -11)?
These are BOTH of the transformations that change an object's orientation.
What is rotation AND reflection?
This is what you get when you solve for x.
-2x + 12 < 18
What is x>-3?
This is measure of the difference between the expected and actual outcome.
What is the residual?
The formula for the sequence 1, 2, 4, 8, 16, ... is this.
What is y=1(2)x or y=2x?
The system of equations 2y=6x-8 3y=9x-12 has this many solutions.
What is infinitely many solutions?
If two triangles can be said to be congruent, the reason is one of these 4 properties.
What are SSS, ASA, AAS, SAS?
This is how you can write this product as a sum.
(6x + 9)(-x + 2)
What is -6x2 + 3x + 18?
