Iride at a speed of 9 kilometers per hour for 14.4 kilometers. for how many hours she ride

1.6 hours

Step-by-step explanation:

Speed v = distance d/time t

v = 9km/hr

d = 14.4km

t = ?

: - v = d/t

vt = d

So. t = d/v

t = 14.4/9

t = 1.6hrs

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
