Whta is the first quartile

the first quarter of the data

Step-by-step explanation:

lets say you have this data

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16

first, count the data, there is clearly 16 here.

split the data into four.

like this;

1, 2, 3, 4,  /  5, 6, 7, 8,/  9 ,10, 11,  12, / 13 , 14 ,15 ,16

the numbers before the first slash is the 1st quartile, the 2nd is before the second, the 3rd is before the third and the 4th is before the fourth slash.

to clear it up. 1, 2, 3, 4 would be your 1st quartile. the first 1/4 of the data.

Hope this helps. Good luck

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
