zach works at the verizon store and wonders if iphones last longer if the screen brightness is set to low. he selects a random sample of 20 brand new iphones from this store and randomly splits them into two groups of 10. for the first group of 10 iphones, he sets the screen brightness to low and then starts a movie. for the second group of 10 iphones, he sets the screen brightness to high and then starts a movie. for each iphone, he measures the amount of time until the battery is all the way dead. he finds that the low brightness iphones lasted longer, on average, than the high brightness iphones. 14.1Part AWhen a diver jumps into a lake, water leaks into the gap region between the diver's skin and her wetsuit, forming a water layer about 0.5 mm thick. Assume that the total surface area of the wetsuit covering the diver is about 1.0 m2, and that the water enters the suit at 13 C and is warmed by the diver to skin temperature of 35C. The specific heat of water is 1.00 kcal/kgC.Estimate how much energy (in units of candy bars = 300 kcal) is required by this heating process.Express your answer using two significant figures.Q = _______________ Candy BarsPart BAn automobile cooling system holds 16 L of water.

Nabil is considering buying a house while he is at university. The house costs $200,000 today. Renting out part of the house and living in the rest over his five vears at school will bring him a net income of, after expenses, $650 per month. He estimates that he will sell the house after five years for $210,000. If Nabil's MARR is 6 percent compounded monthly, should he buy the house? Use annual worth.

ABC Ltd. is looking at ways to improve its cash flow and has decided to extend the timing of its disbursements by one day. In addition, it is negotiating with its bank for the establishment of a lockbox system that will reduce the remittance time of deposits by 2 days. The bank will also provide the company with a detailed analysis of the receipts which saves the company $30,000 in wages. The company's daily remittances amount to $1.5 million and the going rate in the market is 4% per annum for money market funds. For this service the bank charges a monthly fee of $5,000 and would require the company to maintain a $500,000 compensating balance.Advise ABC Ltd. whether or not they should put these changes in place.
