You are member of a data science team which wants to analyse the Opal Card transport data. This dataset contains millions of tap-on / tap-off events where transport users were swiping on and off from trains, buses and ferries. The format is: CardEvents (date, card, mode, time_on, time_off ) Your colleague suggests to store this data partitioned over multiple computers to be able to parallelise the processing. He suggests to use horizontal hash partitioning on the date attribute. Your task in the project is to identify the average length of journeys, which consist of multiple trips across different transport modes (bus, train, etc) each within one hour of the previous trip. How well does your colleague's suggestion to use hash partitioning for the data help you with this?

Ivanhoe Willis is the advertising manager for Bargain Shoe Store. She is currently working on a major promotional campaign. Her ideas include the installation of a new lighting system and increased display space that will add $57,600 in fixed costs to the $387,600 currently spent. In addition, Ivanhoe is proposing that a 5% price decrease ($60 to $57) will produce a 20% increase in sales volume (20,000 to 24,000). Variable costs will remain at $36 per pair of shoes. Management is impressed with Ivanhoe's ideas but concerned about the effects that these changes will have on the break-even point and the margin of safety.
