The pandas library in Python is essential for data manipulation and analysis, offering powerful functions to handle data structures like DataFrames and Series. It allows users to perform operations such as filtering, reshaping, merging, and aggregating data, making it indispensable for data analysts. With pandas, data can be cleaned, organized, and prepared efficiently, allowing for transformations necessary for deeper analysis. Its versatile functionalities support complex data workflows, making it one of the most widely used libraries in data science and analytics. The other options are incorrect because: • Option 1 (NumPy) is primarily for numerical operations and lacks high-level data manipulation tools. • Option 3 (Matplotlib) is for data visualization, not data manipulation. • Option 4 (Seaborn) extends Matplotlib’s capabilities but focuses on visualization. • Option 5 (scikit-learn) is used for machine learning, not data manipulation.
Find the total distance covered by boat in each upstream and downstream in 4 hours if the speed of boat in still water and speed of current is 15 km/h a...
Ratio of distance covered by boat in upstream to downstream is 4:3. Time taken in downstream and upstream is 2hr and 4 hr respectively. If speed of boa...
A boat can travel 45 km downstream in 50 min. The ratio of the speed of the boat in still water to the speed of the stream is 5: 4. How much time will t...
If the sum of upstream and downstream speed is 48 km/hr and the speed of the current is 4 km/hr. Then find time taken to cover 84 km in downward?
On a river, Q is the midpoint between two points P and R on the same bank of the river. A boat can go from P to Q and back in 12 hours, and from P to R ...
A boat covers a distance of 36 kilometers in still water in 24 minutes. If the current's speed is two-fifths of the boat's speed in still water, how lon...
A man rows a certain distance downstream in 5 hours and back to the same point in 8 hours. If the speed of the stream is 4.5 km/hr then what is the spee...
A boat travels 315 km downstream in 7 hours and 135 km upstream in 9 hours. Determine the total time the boat takes to cover 150 ...
Speed of a boat in still water is 10 kmph and speed of stream is 6 kmph. A man rows to a place at a distance of 32 km and come back to starting point. T...
A boat takes 12 hours longer to cover 378 km upstream than it does to cover the same distance downstream. The speed of the stream...
