Lengthof train=X
platform length=180
total distance=x+180
speed=60km/hr=60×5/18=(300/18)m/
Time =18s
Time =Distance/speed
18=X+180/(300/18
18×300=18(X+180)
300=X+180
x=300-180=120
so length of the train=120m
0.09 = 0.00 because 0 in the tenths is nearer to the 0 than the next number or digit :)
The number of different ways to distribute m indistinguishable balls into n
distinguishable urns is given by C(m+n-1,n-1).
For example, the number of ways 6 ball can be placed in 7 boxes is given by C(6+7-1, 7-1) = C(12, 6) = 924 ways.
Answer:
Median
Step-by-step explanation:
Remember ...
Mean = Average
Median = Middle
Mode = Most (the number that appears most)
