You wish to predict the future stock price of Stark Industries (STRK) to develop a trading strategy. One way to model stock prices (in a "normal" market) is to use Brownian Motion. In this model, each day's price is estimated using the previous day's price plus a random amount. For this problem, we will be adding a random number coming from a normal distribution. For the distribution, the standard deviation will be 0.5% of the previous day's price and the mean will be +0.1% of the previous day's price. The mean will be positive if the price one day before is higher than the price two days before, and negative otherwise. For example, to estimate the price for day three, add a random number to the price on day two. The mean and standard deviation of this random number is calculated using the stock price on day two and the trend in price from day one to day two. Simulate the stock price of STRK over one year (250 trading days). Repeat this for many (100,000+) repeated simulations. Produce a A. convergence plot demonstrating that you ran enough simulations B. "spaghetti plot" that shows the daily price for each simulation. Your x-axis should be the trading day (1:250) and the y-axis is the stock price ($). Plot all simulations on this plot, no need for a legend. C. properly-binned, relative-frequency histogram of the stock price only at the end of one year over your repeated simulations Calculate and explain, according to the model, D. Is the stock price after one year normally distributed? E. The probability that the stock price will be above 550 after one year F. The probability that the stock price will be below 450 after one year G. If you bought the stock on day one for $500, would you have made a profit after one year? Problem Parameters: • The stock price on day one is $500 • For day two only, use a mean of zero for the random number • There are 250 trading days in the year Hints/Clarifications: • First, get your program to work for a single trading year before repeating it for multiple simulations • Reset all your quantities at the beginning of each simulation

the system of inequity is

$y\leq -x+4$

$3y> x$

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

the solid line passing through the points (0,4) and (4,0).

$y-4=\frac{0-4}{4-0}(x-0)$

$y=-x+4$

the related equation of solid line is $y=-x+4$ .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

$y-0=\frac{0-1}{3-0}(x-0)$

$3y=x$

the related equation of dashed line is $3y=x$

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

$1=-0+4$

$1=4$

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be $\leq$ . the required inequality is

$y\leq -x+4$

similarly, check the second related equation.

$3(1)=0$

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

$3y> x$

15 points write a system of inequalities to represent the shaded portion of the graph

the most boring ever written

step-by-step explanation:

i am writing something. yes, i plan to make it the most boring thing ever written. i go to the store. a car is parked. many cars are parked or moving. some are blue. some are tan. they have windows. in the store, there are items for sale. these include such things as soap, detergent, magazines, and lettuce. you can enhance your life with these products. soap can be used for bathing, be it in a bathtub or in a shower. apply the soap to your body and rinse. detergent is used to wash clothes. place your dirty clothes into a washing machine and add some detergent as directed on the box. select the appropriate settings on your washing machine and you should be ready to begin. magazines are stapled reading material made with glossy paper, and they cover a wide variety of topics, ranging from news and politics to business and stock market information. some magazines are concerned with more recreational topics, like sports card collecting or different kinds of hairstyles. lettuce is a vegetable.
