The 6000 kg spacecraft (including propellant) in HW 4 Problem 4 had a chemical propulsion system that provided a velocity increment V = 1804 m/s for transfer from the elliptical orbit at apogee to GEO. In this problem, calculate the propellant mass required if the V of the 6000 kg spacecraft was provided by an ion propulsion system with a specific impulse Isp = 3000 s. State any doubts you have about your calculation.

Use technology to construct the confidence intervals for the population variance $\sigma^2$ and the population standard deviation $\sigma$. Assume the sample is taken from a normally distributed population. c = 0.95, s = 34, n = 16 The confidence interval for the population variance is $(oxed{ ext{ }}, oxed{ ext{ }})$ (Round to two decimal places as needed)

The average number of miles (in thousands) that a car's tire will function before needing replacement is 69 and the standard deviation is 13. Suppose that 6 randomly selected tires are tested. Round all answers to 4 decimal places where possible and assume a normal distribution. a. What is the distribution of X? $X \sim N(69, \quad 13)$ b. What is the distribution of $\bar{x}$? $\bar{x} \sim N($ c. If a randomly selected individual tire is tested, find the probability that the number of miles (in thousands) before it will need replacement is between 73.6 and 78.1. d. For the 6 tires tested, find the probability that the average miles (in thousands) before need of replacement is between 73.6 and 78.1. e. For part d), is the assumption that the distribution is normal necessary? Yes No

Exercise 11-10 Cheyenne Company purchased a piece of equipment at the beginning of 2014. The equipment cost $430,920. It has an estimated service life of 8 years and an expected salvage value of $60,840. The sum-of-the-years'-digits method of depreciation is being used. Someone has already correctly prepared a depreciation schedule for this asset. This schedule shows that $61,680 will be depreciated for a particular calendar year. Determine for what particular year the depreciation amount for this asset will be $61,680. Year of depreciation
