Suppose x has a distribution with $\mu = 12$ and $\sigma = 4$. USE SALT (a) If a random sample of size $n = 42$ is drawn, find $\mu_\bar{x}$, $\sigma_\bar{x}$ and $P(12 \le \bar{x} \le 14)$. (Round $\sigma_\bar{x}$ to two decimal places and the probability to four decimal places.) $\mu_\bar{x} = $ $\sigma_\bar{x} = $ $P(12 \le \bar{x} \le 14) = $ (b) If a random sample of size $n = 71$ is drawn, find $\mu_\bar{x}$, $\sigma_\bar{x}$ and $P(12 \le \bar{x} \le 14)$. (Round $\sigma_\bar{x}$ to two decimal places and the probability to four decimal places.) $\mu_\bar{x} = $ $\sigma_\bar{x} = $ $P(12 \le \bar{x} \le 14) = $ (c) Why should you expect the probability of part (b) to be higher than that of part (a)? (Hint: Consider the standard deviations in parts (a) and (b).) The standard deviation of part (b) is ---Select--- part (a) because of the ---Select--- sample size. Therefore, the distribution about $\mu_\bar{x}$ is ---Select--- Submit Answer

Required information Problem 04-50 (LO 04-3) (Static) [The following information applies to the questions displayed below.] Amanda would like to organize BAL as either an LLC (taxed as a sole proprietorship) or a C corporation. In either form, the entity is expected to generate an 8 percent annual before-tax return on a $500,000 investment. Amanda's marginal income tax rate is 37 percent, and her tax rate on qualified dividends and net capital gains is 20%. Assume that BAL will distribute half of its after-tax earnings every year as a dividend if it is formed as a C corporation. Assume the income is not eligible for the QBI deduction. Further, when computing your answers, include the self-employment tax (use a 2.9% marginal rate for self-employment income because Amanda has salary in excess of the wage base limit) but not the additional Medicare tax or the net investment income tax. Problem 04-50 Part a (Static) a. How much cash after taxes would Amanda receive from her investment in the first year if BAL is organized as an LLC? What if BAL is organized as a C corporation? Note: Round intermediate calculations and your final answers to the nearest whole dollar. After-tax cash flow LLC $ 24,470 C $ corporation 12,640

Problem. Calculate numerically the first derivative du/dx of the function u = sin (?x) in the domain x ? [0, 2] using a mesh space of h =0.1 and the following schemes: (a) \frac{du}{dx} \approx \frac{u_{j+1} - u_j}{h}, (b) \frac{du}{dx} \approx \frac{u_{j+1} - u_{j-1}}{2h}, (c) \frac{du}{dx} \approx \frac{u_{j-2} - 8u_{j-1} + 8u_{j+1} - u_{j+2}}{12h} Plot both the discretized derivatives and the analytic derivative on a single graph. Don't forget to label the axes and the legend explaining what each line is. Then, compare the results with the exact solution by calculating the maximum error (i.e., the maximum of the absolute error) and answer How does the maximum error change with the order of scheme precision? Graph the maximum error (y-axis) as a function of the order of scheme precision (x-axis). (Hint: You can use the order of scheme precision (c) is 3, but show how extra if it is proved mathematically).

A type 1-2 shell and tube heat exchanger with a shell inside diameter of (23 1/4 in) and consisting of 324 3/4 in. OD tubes, 14 BWG with a length L= 12 ft distributed in a 1 in. square arrangement and supported by standard baffles spaced at a 25% cut-off spaced at 9 in. intervals is available. Using a heat exchanger it is desired to heat 150,000 kg/h of a crude oil from 20 °C to 57 °C by means of a heat exchanger with a waste product from a distillation unit. The product a of 130,000 kg/h is to be cooled from 146 to 107 °C . Does the heat exchanger work for the required process? distillation product: Cp=2.20 J/g°C ; u=5.2; ρ=868 kg/m^3, K=0.119 W/m°C Crude oil: Cp=1.99 J/g°C; u=2.9cp , ρ=825 kg/m^3; k=0.137 W/m°C
