3. Compute the geometric mean (return) and the final balance after 5 years on a $1,200 investment using the following information: (Year 4 is Negative 18%) Year Return 1 12% 2 8% 3 15% 4 -18% 5 5% 3A. What is the average rate of return for this investment over the 5 years? (convert to % and round to 3 decimal places – example 12.063%) 3B. If you invested 1,200 at the beginning, how much would your investment be worth after 6 years (round to the nearest penny (example – $1,607.45)? (© Chris O'Byrne 2024) 4. Tuition in year 1 were $15,700 and after 4 years of growth, tuition were $24,800. What is the average growth rate (geometric mean) over this 4-year period of time?

You are given the job of designing a bridge that is to be made of concrete slabs that rest on a steel support frame. The total length of the bridge is 284 m, and you want to be sure that the expansion joints are sufficiently large. If the temperature increases by 26\deg C, what is the difference in the new lengths of the concrete and steel components of the bridge?

Consider a study where subjects perform a memorization task under two conditions: (1) with irrelevant background speech and (2) in silence. Let x represent the difference in the error rates for the two conditions—called the relative difference in error rate (RDER). Explain why x is a continuous random variable. Choose the correct answer below. A. The error rates are a percentage, which can each be any of the values between 0 and 100 percent. The difference between the error rates is therefore also continuous. B. The error rates will be rounded to the nearest whole percentage, making the difference between the error rates continuous. C. There are only 2 options for x, either an error was made or it was not. Therefore, the difference between the error rates is continuous. D. There are 3 options for x, an error was made by both groups, an error was made for one group but not the other, or both groups did not make an error.

Q-4 A combination die has to be designed based on the following data a) It has to punch a hole of 120 mm diameter in a steel plate of thickness 6 mm. the material shear strength is 600 MPa. Penetration of the punch is 40%. b) It will also draw a sheet in symmetrical cup shape with 50 mm diameter and 70mm height with same sheet thickness. The corner radius of the cup is 2mm. Determine: i) Diameter of punch die for punching operation ii) Angle on punch if balanced shear is used to bring the maximum load to 250 KN. iii) Diameter of blank required for drawing operation. iv) Find the punch and die sizes and shape for each redraws. v) Total capacity of machine in tons.

Question 5 Qin - Wb + mi h? = m2 u2 The above equation best represents: 1.5 points Save 1. A non-adiabatic piston cylinder device that is initially evacuated, and connected through a valve to a supply line at Pi and Ti. The valve opens and allows the substance to slowly enter the device, while heating, until the pressure inside is in equilbrium with supply line pressure. 2. A rigid tank that is initially evacuated. The tank is connected to supply line at high temperature. The valve opens and allows the substance to enter the system until pressure inside is in equilbrium with supply line pressure. During this process electrical work applies into the system and heat loss appears to surrounding. 3. The energy balance of an adiabatic piston cylinder device initially evacuated. The valve opens and allows the substance to enter the system until the pressure inside is in equilbrium with supplly line. 4. The mass balance of the unsteady state flow system.
