The next two numbers in this sequence: 5, 15, 45, ____, ____
What are 135, 405
200
The three main ways to prove angles are equal in parallel lines
What are corresponding, alternate, and vertical angles (opposite accepted in lieu of vertical)
200
What type of correlation would hours of sleep and GCSE scores have? Why?
What is positive, because...
200
Explain the movement that a gradient of -3 indicates
Three down and one across - which direction? (Hidden bonus! What is the other way to describe that same gradient?)
200
The state Mrs. Jakob is from
What is Vermont
300
The nth term of this sequence: 16, 13, 10, 7, ...
What is -3n + 19 (or 19 - 3n)
300
The formula for finding total degrees in any polygon (you must define your variable; what does it represent?)
What is (n-2) x 180 where n = number of sides
300
If two variables, a and b, have a negative correlation, describe what happens when a increases. Describe what happens when b increase. What if a and b have a positive correlation?
Negative - as a increases, b decreases. As b increases, a decreases. Positive, when either increases, so does the other. When either decreases, so does the other.

The room number of our classroom
What is MFB4
400
The second difference of this sequence: 4, 6, 10, 16, 24, ...
What is +2 (Hidden bonus! What is the nth term? n^2 - (n - 4)
400
Josh measures the exterior angle of a octagon. He found the angle to be 50. Josh claims his octagon is a regular octagon. Is he correct? Explain.
No. The sum of exterior angles is always 360. 360/8 = 45 so all the exterior angles on a regular octagon must each be 45.
400
Using the scatter graph on page 485, question 2, what latitude would you be on if it were 80 F?
What is 23 (Hidden bonus! What is the equation of that line of best fit?) EXTRA BONUS!!! Interpret the gradient of that equation. What does it tell us? MORE BONUS!???!!! Does it makes sense to interpret the y-intercept?
400
The equation of a line that passes through the points (3, 8) and (-3, 12)
What is y = -2/3x + 10

Who is Rita Ora?
500
The nth term for this sequence: -9, -6, -1, 6
What is n^2 - 10
500
____a/______ / ___/b_____ The two lines above are parllel. If a = 102, what is the measure of angle b? Show your working and give reasons
What is 78 because b is on a straight line with a's corresponding angle. 180 - 102 = 72
500
A scatter graph compares height to arm span. The gradient of the line of best fit is 1. What does this mean in real-life terms?
For every cm of height, there is one cm of arm span. (Hidden bonus! Does it make sense to interpret the y-intercept for this graph?)
500
