Question
What is the main objective of cluster analysis in data
analytics?Solution
To classify data into mutually exclusive groups based on predefined criteria
Ratio of speed of boat in downstream and speed of stream is 8:3, if speed of current is 6 km/hr, then find distance travelled (in km) upstream in 5 hours.
Megha got 38% of the maximum marks in an examination and failed by 6 marks. In the same examination Teena got 42% of the total marks which is 14 marks m...
A boat covers some distance downstream in 1 hour. It covers 3/2 hours. If the velocity of the stream is 3 kilometers per hour, then what will be the vel...
Ratio of speed of boat in downstream and speed of stream is 7:4, if speed of current is 8 km/hr, then find distance travelled (in km) upstream in 7 hours.
A boat can travel 38 km downstream in 57 min. The ratio of the speed of the boat in still water to the speed of the stream is 3: 2. How much time will t...
The ratio of the speed of boats ‘A’ and ‘B’ in still water is 8:9, respectively. The speed of the current is 25% of the speed of boat ‘A’ in...
The speed of boat downstream and upstream is 36 km/hr and 26 km/hr respectively. Time taken to travel a distance of (k + 60) km downstream and (l + 40) ...
A boat can cover 195 km in downstream in 10 hours and 140 km in upstream in 14 hours. Find the distance travelled by the boat in still water in 4 hours.
Speed of a boat in still water is 48 km/h and the speed of stream is 25% of the speed of boat in still water. If the time taken by boat to cover a dista...
A boat running downstream covers a distance of 55 km in 5 hrs and covering the same distance upstream in 11 hrs. What is the speed of a boat in still wa...
