10 x 3 = 30km
14, 56, 11, 31, 68, 55, 45 What is the mean?
40
Add them all up and divide by 7 (there are 7 numbers)
44, 88, 72, 41, 63, 34 What is the range?
54
What 2 things do you look for on a graph to see if it is proportional?

The probability of rolling a 2 on a 6-sided die
1/6 because there is only one 2
Anton is snapchatting on a roller coaster. The roller coaster is moving 70km/h and takes Anton 490km. How long was Anton riding the roller coaster?

65 is in the middle when you put them in order
78, 34, 32, 34, 78, 78, 68, 32, 34, 78 What is the mode?
78
The probability of getting an even number on a 6 sided die
3/6 or 1/2
A few students in 6E were chasing Mr. White trying to convince him that Spongebob was made of cheese. If they are on their bikes moving 25km/h, how far did they chase Mr. White after a 1/2 hour (30 minutes)?
If 25km = 1 hour, then 12.5km = 1/2 an hour
12.5km
36, 54, 59, 82, 20, 61, 48, 78, 84 What is the median?
59
32, 23, 22, 33, 33, 23, 32, 23, 22 What is the range?
33-22 = 11
The range is 11
In a box there are 7 red marbles, 8 green marbles, 3 blue marbles and 6 orange marbles. What is the probability of reaching in and picking a green marble?
Sloths can move 2km/h. How many m/h would that be?
2km= 2000m
2000m/h
83.59 , 79.06 , 84.56 , 81.23 , 84.56 , 80.33----What is the median?
82.41
If you put them in order, 81.23 and 83.59 are in the middle. Add them up and divide by two
11, 11, 11, 11, 11, 11 What is the range?
There are 2 lottery games that you could play. One lottery has a 1/4 chance of winning, the other lottery has a 3/12 chance of winning. Which lottery would you rather play and why?
Either one! They both have the same chance of winning
3/12 = 1/4
Adonay was given some sugar so he has A LOT of energy, and he was running 75km/h. How far did he run in 10 minutes?
75km/h means 75 km in 60 minutes.
Since 10 minutes is 6 times smaller than that, we can do 75/6
Adonay ran 12.5 km.
Mr. Macabalang went bowling. His first game he scored 97, his second game he scored 100, his third game he scored 99. If he averaged a scored of 100 after 4 games, what did he score in his fourth game?
104
If he averaged 100 per game, then after 4 games he bowled 400. So if he had 97+99+100 in his first 3 games, he must have bowled 104 in his last game.
2, 3, 4, 5, 5, 4, 3, 2
There is no mode - they all show up the same amount of times
