100
What does it mean for a relation to be a function?
The relation has no repeating x-values
100
What is another word for "average rate of change"?
SLOPE
100
What does "r" stand for in statistics (two words)
Correlation Coefficient
100
What is the degree of the polynomial below?
4x^2-9-x^3+7
Third degree or cubic
100
What does "DOTS" stand for?
Difference of Two Squares
100
A "non-terminating, non-repeating decimal" is the definition of a...
Irrational Number
100
A question from The National Mathematics Contest in 1991...
Three days ago, yesterday was the day before Sunday. What day will it be tomorrow?
Three days ago, yesterday was the day before Sunday, so three days ago was itself Sunday.
That means today is Wednesday, so tomorrow is Thursday
200
What does "VLT" stand for AND how does one use the VLT?
The "Vertical Line Test" is used to see if a graph is a function. You draw vertical lines and see how many times each vertical line touches the graph. If it touches the graph more than once, the graph is not a function!
200
What is the formula to find "m" in the below equation?
y=mx+b
m=(y_2-y_1)/(x_2-x_1)
200
What is the difference between the "mean" and the "median" of data?
Mean = average of the data
Median = middle value of the data (in numeric order)
200
Written in standard form, what is the sum of
4x^2-5x+6
and
-7x-6x^2-9
-2x^2-12x-3
200
(24x^2+15x)
3x(8x+5)
200
What are the "zeros" or "roots" of a function?
When the graph of the function crosses the x-axis
400
Which table represents a function?
4) becuase the table has no repeating x-values
400
The following conversion was done correctly. What are the final units for this conversion?
(ft)/(sec)
400
What is the median of the data values below?
89
400
(x^2-5x-2)-(6x^2-7x+3)
-5x^2+2x-5
400
x^2-5x-6
(x-6)(x+1)
400
The sum is irrational because the square root of 2 is irrational.
OR
7.07106781187 is irrational because it is a non-terminating, non-repeating decimal
OR
7.07106781187 is irrational because it cannot be written as a fraction of two integers
600
State a value of x such that the relation below is not a function.
R={(-2,4),(-1,-2),(x,-4),(1,2)}
-2, -1, or 1

The table below shows the radioactivity level of a substance after the given time, t, in seconds.
What is the average rate of change in radioactivity level over the interval 1 ≤ t ≤ 3?
-3.75
((2.5)-(10))/((3)-(1))
600
In the boxplot below, what is the maximum value, the median value, and the first quartile? (I need all 3 stated clearly)
first quartile: 25
median: 30
maximum: 50
600
Simplify:
(2x-3)(7x+4)

-153.71
((53)-(1129))/((2013)-(2006))
800
What is the IQR of the boxplot below?
