Patient Profile: Patient is 59 years old with a current weight of 240 pounds; BMI is 41 (5’4’’tall). She is sedentary (no physical activity whatsoever) and works a desk job. She had a stress test recently and everything was normal. She states that she participated in a walking program last year but had to drop out after 3 weeks because she developed plantar fasciitis. She also states that the walking was pointless because she did not lose any weight during those 3 weeks.

What would be the next focus for her regarding improving the healthcare evaluations? Why? Describe how you would approach this. That is, how would your exercise/ weight loss prescription look for this person?

computer output giving descriptive statistics for the percent of the population that is obese for each of the 50 states, from USStates dataset, is given in the table below. since all 50 states are included this is population not a sample

variable N N    mean. se mean. stdev. minimum
                50, 0, 28.766, 0.476,    3.369, 21.300

Be sure to answer all parts. Write the balanced equations corresponding to the following rate expressions: a) rate = − 1 3   Δ[CH4] Δt = − 1 2   Δ[H2O] Δt = − Δ[CO2] Δt = 1 4   Δ[CH3OH] Δt (Click in the answer box to activate the palette. Do not include states of matter.) b) rate = − 1 2   Δ[N2O5] Δt = 1 2   Δ[N2] Δt = 1 5   Δ[O2] Δt (Click in the answer box to activate the palette. Do not include states of matter.) c) rate = − 1 2   Δ[H2] Δt = − 1 2   Δ[CO2] Δt = − Δ[O2] Δt = 1 2   Δ[H2CO3] Δt

The nature of federalism is dynamic. It undergoes changes as changes in the demands of society occur. What is the relationship between contemporary politics and trends in the size and power of the federal government? Many state governments argue that making federal funds dependent on state cooperation with national goals is “federal blackmail.” Why must the federal government use these financial incentives (and disincentives) instead of simply legislating that states do what the federal government wants? Does federalism retain substantial value in the modern era, or is it an obsolete obstruction which should be abandoned? Do you think it is better to leave issues like gun control and capital punishment to individual states?

Medical tests were conducted to learn about drug-resistant tuberculosis. Of 142 cases tested in New Jersey, 9 were found to be drug-resistant. Of 268 cases tested in Texas, 5 were found to be drug-resistant. Do these data suggest a statistically significant difference between the proportions of drug-resistant cases in the two states? Use a .02 level of significance. What is the p-value, and what is your conclusion?

Test statistic =  
p-value =

- Select your answer -Reject the null hypothesisDo not reject the null hypothesisItem 3

True or False

There is a significant difference in drug resistance between the two states. New Jersey has the higher drug resistance rate.

- Select your answer -TrueFalseItem 4

excited state vs the number in the ground state for the temperatures shown below. Remember that g values are simply the number of states present in each orbital. g values for the 3p and 3s orbitals are shown below. The average wavelength of light required to excite an atom from 3s to 3p for Na⁺ and Mg⁺ is 5.89 x 10² nm and 2.80 x 10² nm respectively.

1. What is the energy difference between the 3s and 3p states of each atom?

2. Calculate the proportion of excited state to ground state atoms for Na⁺ and Mg⁺ in microwave-induced argon plasma (2.50 x 10^3oC)

3. In an electric spark (4.00 x 10^{4 o}C)

4. At 20.0 ^oC.

globalization

1. “The inexorable integration of markets, nation-states, and technologies to a degree never witnessed before--in a way that is enabling individuals, corporations, and nation-states to reach around the world farther, faster, deeper and cheaper than ever before . . . . the spread of free-market capitalism to virtually every country in the world "
2. "The compression of the world and the intensification of consciousness of the world as a whole . . . . concrete global interdependence and consciousness of the global whole in the twentieth century"
3. "A social process in which the constraints of geography on social and cultural arrangements recede and in which people become increasingly aware that they are receding.

Which of the three perspectives on globalization discussed makes the most sense to you? Why? tell one experience/observation you have had/made that supports your choice of perspective.

A piston-cylinder device contains a saturated mixture of steam and water having a total mass of 0.5 kg at a pressure of 160 kPa and an initial volume of 100 liters. Heat is then added and the fluid expands at constant pressure until it reaches a saturated vapor state.

a) Draw a diagram representing the process showing the initial and final states of the system.

b) Sketch this process on a P-v diagram with respect to the saturation lines, critical point, and relevant constant temperature lines, clearly indicating the initial and final states.

c) Determine the initial quality and temperature of the fluid mixture prior to heating. [quality x1 = 0.182, T1 = 113.3°C]

d) Determine the final volume of the steam after heating. [0.546 m3 (546 liters)]
