Mean, Median, and Mode
Mean is another word for what?
Average
How do we convert fractions to decimals?
Divide the top of the fraction by the bottom of the fraction
What is the probability of flipping heads on a coin?
1/2, 50%, 0.5, 50/50
Slope is the same as what over what?
Rise over run
Things that go into the function are called:
Inputs
What is the definition of mode?
The data point(s) that appears the most in a data set
How do I convert a decimal to a percentage?
Multiply the decimal by 100
How do we find probability?
("wanted outcomes")/("all outcomes")
True or False: Slope can only be positive.
False
What is function notation?
When we replace the y with f(x)
How do we find the median?
1. Order all the numbers from smallest to greatest
2. Cross out the first and last number
3. Repeat until there is one number left
4. If there are two numbers left, find the average of the two numbers
Convert 6/7 to a decimal
0.857
What is the difference between theoretical and experimental probability?
Theoretical-What SHOULD happen
Experimental-What ACTUALLY happened
Calculate the slope between the two points:
(4, 1) and (6, -7)
-4
How do we know if something is a function?
Find the mean of the following numbers:
67 41 21
43
What is 0.67 as a percentage?
67%
50%. The coin is fair, so the experimental probability does not matter.
What is the slope of a horizontal (left to right) line?
Evaluate the function f(x)=8x-2 for the input x=1
f(1)=6
What is the median of the following numbers:
0 4 -5 -8 67 -2 -1
-1
Convert 1738% to a decimal
17.38
What is the probability of rolling either an odd or even number on a 6-sided die?
100%. A 6-sided die contains only odd or even number, so it is guaranteed to get either an odd or even number.
What is the slope between the following points:
(1, 5) (1, -4)
Undefined
For the function solution f(9)=5, what is the input and output?
Input = 9, Output = 5
