In statistics, which measure is defined as the value that separates the higher half from the lower half of a data sample?
Median
How many quadrants does a graph have? And, What is the difference between the x-axis and the y-axis on the graph?
4
On a graph, the "y-axis" refers to the vertical line, while the "x-axis" refers to the horizontal line; essentially, the y-axis measures values going up and down, while the x-axis measures values going left and right.
What is the sum of a triangle?

Mean
On a graph, figure A is a triangle with three points, (1,-1) (6, -1), and (4, -6). Find the quadrant of the preimage. Then reflect the triangle vertically, and rotate the triangle 270 degrees. What is the new location of figure A.
The preimage is in quadrant 4, and the image is back in quadrant 4.
What is a equilateral triangle?
A triangle with all three sides and angles that are equal.
What do we call lines that intersect at a right angle?
Perpendicular Lines
If the radius of a circle is 45, what is the diameter?
The diameter is 90.
Which of the following terms describes the difference between the highest and the lowest values in a data set?

I am a full circle, first angle is 86+4x degrees, second angle is 46+2x degrees. Can you solve for X, and what are the values my two angles.
86+4x+46+2x=360
132+6x=360
6x=228
x=38
In statistics, what does the term "mean" refer to?
The average of all values in a data set.
What are the difference between each quadrant?
Quadrants are sections of a coordinate plane that are defined by the values of x and y. The four quadrants are:
All of my angles are less than 90 degrees and I have no equal sides.
Am I right triangle?
Yes or No, and why?
Acute triangle is my name.
Right triangles have at least one angle equal to 90 degrees.
Multiplying three Negative numbers will result in a positive answer or a negative answer.
Negative Answer
The circle is split into 10 equal sides, what are they measurement?
36 degrees

B (8,-9)
What quadrant do point B belong in?
Quadrant IV
Triangle has sides that are both 8 and a side that is 15.
Can you draw it? Why or why not?
Yes because the sides are greater than the base.
When finding the percent of a number, do you divide or multiply?
What's 15% of 45.
Multiply.
!5% of 45= 6.75
