I need help with this problem.
1. Research stock company of your choice: I chose Apple company.
-Determine mean price and standard deviation
-Use randn to predict stock prices over the next year
2. Develop Stock Trading Algorithm to determine when to buy, when to sell, how many shares to buy/sell on each day
3. Each time you buy or sell stocks is subject to a 3% commission fee or $40 fee, whichever is higher
4. Model algorithm over a 1-year period (250 trading days)
5. Determine the expected average profit, minimum profit, maximum profit, and standard deviation for that 250-day period
6. Re-run your algorithm for the 250 days at least 10 times. Calculate the average profit for the 10 realizations (the average of each of the 250-day average profits), the standard deviation of the 10 realizations, the maximum profit, and the minimum profit.
7. Be sure to use comments (%) in your code to explain what each step is supposed to accomplish (helps with partial credit!)

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

A-mn has a cubic structure with a0 0.8931 nm and a density of 7.47 g/cm3. b-mn has a different cubic structure, with a0 0.6326 nm and a density of 7.26 g/cm3. the atomic weight of manganese is 54.938 g/mol and the atomic radius is 0.112 nm. determine the percent volume change that would occur if a-mn transforms to b-mn.

Air flows over a heated plate à t a velocity of 50m/s. the local skin factor coefficient at a point on a plate is 0.004. estimate the local heat transfer coefficient at this point.the following property data for air are given: density = 0.88kg/m3 , viscosity 2.286 x 10 ^-5 kgm/s , k = 0.035w/mk ,cp = 1.001kj/kgk. use colburn reynolds analogy.
