10. The dot plot shows how many games
Oksi-84 [34.3K]

Answer:

A : False

B : False

Step-by-step explanation:

<em>A : The mode of a data set is whichever number comes up the most.</em>

8 comes up the most times, so 8 is the mode.

<em>B : The median is a number which is in the middle of a data set</em>

This is the data set as a list of numbers :

2, 5, 5, 5, 6, 6, 8, 8, 8, 8

the two sixes are in the middle, if there are 2 numbers in the middle, add them together and divide by two,

6 + 6 = 12

12 / 2 = 6

6 is the median.

Mark tranferred songs from his computer onto his portable music player. he transferred 2 6/7 songs in 1 2/3 minutes. How many so
SCORPION-xisa [38]
So basically; 
 2 6/7 : 1 2/3
as a top heavy fraction is...
20/7 : 5/3 
divide both sides by 5/3 to get x:1
12/7 : 1 
so he transfers 12/7 songs or as a mixed fraction 1 5/7

A dot was running along a number line.
lana [24]

Answer:

The distance would be 64 and 4 miles per hour would be its average speed.

Step-by-step explanation:

On a number line 34 to 0 is 34 points. And 0 to -34 is also 34 points. Add them together and you will get the distance. To find the average speed divide the distance by the time it took to cover that distance in this case 17 minutes and you will find the average speed of the dot.
