Geometry
What shape has three sides?
Triangle
The middle value of an ordered data set
Median
What is the theoretical probability of rolling a dice and getting the number 4?
1/6
define "percent"
"out of 100". Percents are a measure that quantifies a proportion in terms of parts out of 100.
In the equation:
5x - 25 = 50
What is the variable?
What shape has four sides of equal length and all angles are right angles?
Square
the sum of all the numbers in a data set divided by the number of numbers in the data set
mean (average)
What is the theoretical probability of flipping two coins and getting both heads?
1/4
Give a fraction that is equivalent to 15%
15/100, 3/20
In the equation:
5x - 25 = 50
What is the coefficient?
What shape is defined as the set of all points equidistant from a point in the plane?
Circle
The most commonly occurring number in a data set
Mode
Define "sample space"
the set of all possible outcomes for a probability event.
What is 30% of 200?
60
What is this solution to this equation?
5x - 25 = 50
x = 15
5x - 25 = 50
5x = 75
x = 15
What shape is defined as any quadrilateral with two pairs of opposite parallel sides?
Parallelogram
the difference between the largest and smallest number in a data set
range
Define "Probability Event"
The set of all outcomes that lead to some specified result. For example, the event of getting 2 heads and 1 tails when flipping 3 coins is made up of all outcomes where exactly 2 heads and 1 tails occur.
A shirt initially costs 40$, but then is discounted by 20%. What is the discounted price?
40 - 0.2*40 = 40 - 8 = 32$
What is this solution to this equation?
-7.5x + 30 = -30
x = 8
What number is defined by the ratio of the circumference of a circle to its diameter?
Pi, which is approximately 3.14.....
the difference between the third and first quartiles of a data set. 300 Bonus points if you can define both 1st Quartile and 3rd Quartile
Interquartile Range
What is the probability of rolling 2 six-sided dice and getting a sum of 7?
1/6
A shirt was discounted by 35%, and now costs 32.50$. What was the original price?
50$
(1-0.35)x= 32.50
so, x = 32.50/0.65 = 50
What is this solution to this equation?
(-3x + 30)/3 = 5
x = 5
