1 Define big data analytics and explain how big data analytics can help improve a firm's value i.e. increase      the company's share price.         2 Mohamed Salah's uncle is going to give him $250 a month for the next two years starting now.       If Salah banks in every payment in an account paying 6% p.a compounded monthly, how much will      he have at the end of three years? Show your timeline and detailed calculations.         3 The Cruise's family wants to make a home improvement that is expected to cost $60,000. They      want to fund as much of the cost as possible with home equity loan but can only afford payment      of only $600 per month. Their bank offers equity loan at 12% p.a compounded monthly for a      maximum term of 10 years.      a) How much cash do they need as a down payment? 

     b) Their bank account pays 8% compounded quarterly. If they delay starting the project for         two years, how much would they have to save each quarter to make the required down         payment if the loan rate and estimated cost remain the same?         4 Madeleine Stowe buys stock in Headwind Publishing Company. She will receive dividends of $2.00,      $2.40, $2.88, and $3.12 for the next four years. She assumes she can sell the stock for $50      after the last dividend payment (at the end of four years). If the discount rate is 12% p.a, what is the      present value of the future cash flows? The present value of future cash flows is assumed to equal      the value of the stock. (Round all values to two places to the right of the decimal point).
