Time value of money: Scenario: You've received an inheritance of $50,000 and are contemplating two options: investing the money or using it for a down payment on a house. Option 1: Invest the $50,000 in a mutual fund that historically generates an average annual return of 7%. Option 2: Use the $50,000 as a down payment on a house that costs $250,000. The mortgage interest rate is 4% per year for a 30-year term. Assuming both investments or options are held for 30 years, calculate the future value of each opportunity to see which one might yield more.

Part II - Show your work [16 Marks] 3. A composite wall is shown in the figure below. The inner side of the wall is subjected to air flow at 430°C with a heat transfer coefficient of 25 W/m²°C and the outer side is subjected to air flow at 55°C with heat transfer coefficient of 10 W/m²°C. If $k_a$ = 150 W/m²°?, $k_b$ = 30 W/m²°C, $k_c$ = 65 W/m²°C and $k_d$ = 50 W/m²°C, assuming one dimensional heat flow; a. Draw the resistance network and find the value of all involved thermal resistances b. Find the rate of heat transfer across the wall c. Find the inner surface and outer surface temperatures [3 marks] [1mark] [2 marks]

please help me with the whole of this question 3 3. [20 marks] Suppose we are working in a flat Universe. Dynamics in the inflationary epoch are governed by a scalar field in a potential V(). The energy density and pressure are, respectively, 1 1 (3) E 1 1 p (4) Page 1 of 2 [2 marks] State the conditions under which the equation of state parameter w = -1 [8 marks] Derive (5) [4 marks] This equation is supplemented by the Friedmann equation (k = 0): (6) 3c2 (2 hc3 differential equation for . . [6 marks] Show that (7) Using this fact and the result from the previous part of the problem, write a first order The reason this is interesting is that the numerical solution of the first order differential equation you have obtained indicates that inflation is a future attractor - i.e., different initial conditions lead to the same behavior at late times.

ST3501 Exercise 1 of 2022 ... ST 3424: Survey Methods and Applications Exercise 1 13 January 2022 Question 1: Six students who have applied for a course were given a test to assess their ability and their scores were recorded as shown in Table 1.1. Table 1.1: Scores of Students Student Score Y 670 Y 720 Y 650 Y 720 Y 560 Y 700 (a) Select all possible samples of size 2 by simple random sampling with replacement and (i) Show that the sample mean is an unbiased estimator of the population mean. (ii) Show that the sample mean square error s is an unbiased estimator of the population mean square error S. (b) Select all possible samples of size 2 by simple random sampling without replacement and repeat what you did in i and ii under (a) above. Question 2: A complete enumeration of six firms was conducted where firms were asked about, among other things, their number of employees and intention to employ more people. Their responses were recorded as shown in Table 2.1. Table 2.1: Responses of Firms Firm Number of Employees (Y) Intention to Employ More People A 9 Yes B 8 Yes C 6 No D 2 No E 1 No F 5 No For the data on firms given in Table 2.1; (a) Find the population proportion for firms that intend to employ more people (b) Select all possible samples of size 2 by SRSWOR and show that the sample proportion is an unbiased estimator of the population proportion. (c) You can use samples of size 3 by SRSWOR and repeat what is required in (b) above. Question 3: A simple random sample of 6 bulbs was selected from a lot of 100 for the purpose of estimating its quality. The life of each bulb selected was measured by letting it run until it burned out. The results from the test are as follows: Bulb No. Life Duration (Hours) 9 50 12 10
