Circles
What percent does a full circle represent? How many degrees are in a full circle?
100% , 360 degrees
How many quadrants are on a Cartesian plane, and how are they labelled (clockwise or counterclockwise)
4, counterclockwise
You have completed the experiment if you have collected experimental and if you are doing the statistical probability based on chance, it is theoretical.
What tool is used to measure angles?
Why is adding and subtracting different from multiplication and division with decimals?
You don't line up the decimals for multiplication/ division.
If a sector is 90°, what percent of the circle is it?
25%
What kind of transformation spins an object around a point?
Rotation
What is the theoretical probability of rolling a 3 on a regular die?
1/6 16%
What is a line segment?
A segment that has 2 distinct endpoints.
What is the divisibility rule for 9
the sum of the digits is a multiple of 9
What is the area of a circle with radius 3 cm? (Use π ≈ 3.14). don't round
28.26 cm2
When rotating about the origin, if your (x,y) pair change to (-y,-x) you've completed a rotation of? 90, 180, 270 or 360 degrees?
180 (it doesn't matter if you go clockwise or counter clockwise for 180 degrees)
If you flip a coin 10 times and get 7 heads, what is the experimental probability of getting heads?
7/10, 70%
What is a ray?
A line with one endpoint and one end that goes on indefinitely.
If I am multiplying 2 decimal numbers with 2 decimal places each, my product will have how many decimal places?
4
What is the circumference of a circle with radius 5 cm? (Use π ≈ 3.14)
31.4 cm
When rotating about the origin, if your (x,y) pair changes to (-x,y), you've completed a rotation of? 90, 180, 270 or 360 degrees? Describe how to get there clockwise and counterclockwise.
90 degrees counterclockwise, 270 degrees clockwise
Which central value tendency is defined by the value that appears most often in a data set?
Mode
What is a bisector?
Splitting something in half or into congruent pieces.
If my divisor has 3 decimal places and my dividend has none, once the decimal is moved, it will be sitting between which 2 place values?
thousandths and ten thousandths
What happens to the area of a circle if the radius doubles?
The area quadruples because the radius is squared.
What is the image of point (2, 3) after a reflection over the x-axis?
(2,-3)
Median is your central value when data points are in chronological order, and mean is your average of the sum of all data points divided by the number of data points. This is your best and most accurate central tendency as long as there are no outliers.

Round this number to the hundredths place
1 679. 2610
1 679. 26
4 or less let it rest (drop all values after the place value)
5 or more raise the score (add one to the place value you are rounding to, all number behind it are dropped)
