Find the matrix A' for T relative to the basis B'. $T: R^3 \rightarrow R^3, T(x, y, z) = (x, y, z), B' = \{(1, 0, 1), (0, 1, 1), (1, 1, 0)\}$ $A' = \begin{bmatrix} \Box & \Box & \Box \\ \Box & \Box & \Box \\ \Box & \Box & \Box \end{bmatrix}$
1. Use the microeconomic theory of fertility to explain how increasing affluence may be associated with a reduction in the fertility rate. 2. Suppose that families paid substantial dowry at marriage. What effect would this have on desired family size? 3. What effect would one predict for desired family size if family members were to cease undertaking unpaid household labour and undertake instead marketed labour? 4. Take the following data as referring to 2000 (they come from UNDP (2001), \( P \) and \( A \) are for 1999 and \( T \) uses \( \mathrm{CO}_{2} \) data for 1997), and the world as being the sum of these three groups of nations. \begin{tabular}{lccc} \hline & \( P \) (millions) & \( A \) (PPP US\$) & \( T \) (tonnes) \\ \hline Rich OECD & 848 & 26050 & 0.0004837 \\ EE and CIS & 398 & 6290 & 0.0011924 \\ Developing & 4610 & 3530 & 0.0005382 \\ \hline \end{tabular} a. Calculate total world \( \mathrm{CO}_{2} \) emissions in 2000. b. Work out the 2000 group shares of total population and \( \mathrm{CO}_{2} \) emissions. c. Assume population growth at \( 0.5 \% \) per year in Rich OECD and EE and CIS and at 1.5\% per year in Developing, out to 2050. Assume The origins of the sustainability problem 55 per capita income growth at \( 1.5 \% \) per year in Rich OECD, at 2.5\% per year in EE and CIS, and at \( 3.0 \% \) in Developing, out to 2050. Work out total world emissions and group shares of the total for 2050, and also group shares of world population. By what factor does total world emissions increase over the 50-year period? d. For the same population growth and per capita income growth assumptions, by how much would \( T \) have to fall in Rich OECD for that group's 2050 emissions to be the same as in 2000? With Rich OECD emissions at their 2000 level in 2050, assume that \( T \) for EE and CIS in 2050 is the same as \( T \) for Rich OECD in 2000 (which would be \( 2050 T \) for EE and CIS, being about half of its 2000 level) and work out what total world \( \mathrm{CO}_{2} \) emissions would then be.

Find the exact shaded area under these functions. f(x) = 1.5 f(x) = x + 1 f(x) = \sqrt{4 - x^2} A = A = A =
repay. Suppose that all conditions are met and that the population standard deviation is sigma =1.1 thousand dollars. In this problem, we will systematically investigate what happens to the length of the confidence interval as the sample size quadruples. to three decimal places.) The 95% confidence interval based upon n=100 is ( , ) thousand dollars. to three decimal places.) The 95% confidence interval based upon n=400 is ( , ) thousand dollars. answers to three decimal places.) The 95% confidence interval based upon n=1,600 is ( ) thousand dollars. gambler suffers, a study surveyed a random sample of 100 gambling addicts. The amount of debt to be repaid is examined, and it is found that they have an average of 7 thousand dollars in gambling debts to repay. Suppose that all conditions are met and that the population standard deviation is = 1.1 thousand dollars. In this problem, we will systematically investigate what happens to the length of the confidence interval as the sample size quadruples. (a) Calculate a 95% confidence interval for the mean amount of debt owed (in thousands of dollars) for all gambling addicts using the given sample size, n = 100. (Use a table or technology. Round your answers to three decimal places.) The 95% confidence interval based upon n = 100 is ( I thousand dollars. (b) Calculate a 95% confidence interval for the mean amount of debt owed (in thousands of dollars) for all gambling addicts using the given sample size, n = 400. (Use a table or technology. Round your answers to three decimal places.) The 95% confidence interval based upon n = 400 is ( ) thousand dollars. (c) Calculate a 95% confidence interval for the mean amount of debt owed (in thousands of dollars) for all gambling addicts using the given sample size, n = 1,600. (Use a table or technology. Round your answers to three decimal places.) The 95% confidence interval based upon n = 1,600 is ( thousand dollars.

Below is an Extraction Flowchart for the separation of a three-component mixture. Several of the steps are missing, as well as several of the structures, throughout the flowchart. Using the ChemDraw Template provided, fill in the missing steps and structures. In each step, be sure that all necessary reagents (organic solvents, aqueous solutions, drying agents) and manipulations (shaking/mixing, separating phases, filtering/decanting) are included in their proper order. Clearly indicate the structures of the compounds at each step in the process, and be sure to refer to Lab Manual Section 8.5 for an example of the format. 1. Add CH$_2$Cl$_2$ 2. Add HCl 3. Mix 4. Allow layers to separate $\text{O}$H $H_3C$ $\text{N}$H$_2$ CHCl$_3$ H$_2$O CHCl$_3$ Separate H$_2$O H$_2$O CHCl$_3$ CHCl$_3$ Separate H$_2$O CHCl$_3$
