1. The output of an economy is characterized by a Cobb-Douglas production function with constant return to scale and an output elasticity with respect to capital equal to 0.3. Also given are the following parameters: 30% saving rate, 5% depreciation rate, 2% population growth rate, and the technology factor is 2.

a). Find the capital-labour ratio, and also the output, consumption and investment on a per capita basis in the steady state equilibrium.

b). Is a government policy that raises the saving rate to 40% socially desirable? Explain your answer with reference to a comparison of this new steady state equilibrium and the initial steady state equilibrium in a) above.

c). If the initial capital-labour ratio is 30, is the economy operating efficiently in the sense that welfare cannot be improved? Explain concisely. What if the initial capital-labour ratio is 15? Again explain concisely.

An electrical machine dissipates 2.5 kW. All cooling of the unit takes place through one exposed surface, measuring 120 mm × 190 mm. All other surfaces of the unit are insulated. 50 fins are mounted on the exposed surface. The fins are made of aluminium alloy 2024-T6, and each one measures 120 mm × 2 mm in cross-section and 80 mm in length (normal to the surface they are mounted on). The fins and base surface are exposed to fan-driven air at 15°C with a convection heat transfer coefficient of 60 W m–2 K–1. Calculate the steady-state temperature of the power supply’s exposed surface. (b) To increase the heat transfer rate through a set of fins, without changing the base temperature, would it be more effective to increase the number of fins by 20%, or to increase the length of each fin by 20%? Explain your answer.

Would the Difference in conditions (DIC) cover political unrest? During the protest, several businesses are destroyed and damaged by the individuals, and many have insurance to assist. What type of Commercial insurance would cover their property? Please explain in detail ?

1) What are the hexadecimal, and octal equivalents for the unsigned binary value 0111 0000 1101? (note the spaces in the binary are for readability (like a comma in a decimal value; there is only a single 12 bit binary value)

PLEASE EXPLAIN IT IN DETAIL

STAT_14_3

Ronit has a box with beads. The beads are opaque or transparent and available in several colors.
The probability that a random bead will be red is 0.3. The probability that a bead will be transparent is 0.6.
Of the red beads - the probability of a random bead being transparent is 0.5

A. Remove 8 beads from the box at random and upon return (sampling with replacement). What is the probability that exactly two of them will be red?
B. Take beads out of the box accidentally and on return (sampling with replacement) until you first remove a transparent bead.
1. What is the probability that more than 4 beads will be removed?
2. The first two beads taken out were not transparent. What is the probability of getting 7 beads out of the box?
C. Remove 10 beads from the box at random and upon return (sampling with replacement). What is the probability that exactly three of them will be red and transparent, two opaque and red and 5 transparent and red?

Use your knowledge of glycogen storage and breakdown to explain the consequence of defects in the glycogen storage pathway.

2. For each of the following goods, state whether it is excludable or nonexcludable.

a. cable TV service

b. free public wifi

c. the local public library

d. a ride in an Uber, Lyft, or taxi

3. For each of the following goods, state whether it is rival or non-rival.

a. a large public park

b. a freeway that requires toll payments

c. a freeway that does not require toll payments

d. a fresh avocado from the supermarket

4.  NOTE: read carefully on page 310 in your textbook before responding.

a. Suppose you buy a new pair of headphones. Is your purchase rival or non-rival? Is it excludable or nonexcludable? Briefly explain why.

b. Suppose that by living in the United States, you benefit from strategic reserves of petroleum held by the U.S. government (Links to an external site.). Is your benefit rival or non-rival? Is it excludable or nonexcludable? Briefly explain why.

5. A postage stamp is something offered by the federal government in the United States. Think about a postage stamp in the context of rival/non-rival and excludable/nonexcludable. With that in mind, is a postage stamp classified as a "private good" or "public good" in the United States?

To complete this exercise you need a software package that allows you to generate data from the uniform and normal distributions.

(i) Start by generating 500 observations xi - the explanatory variable - from the uniform distribution with range [0,10]. (Most statistical packages have a command for the Uniform[0,1] distribution; just multiply those observations by 10.) What are the sample mean and sample standard deviation of the xi?

(ii) Randomly generate 500 errors, ui, from the Normal[0,36] distribution. (If you generate a Normal[0,1], as is commonly available, simply multiply the outcomes by six.) Is the sample average of the ui exactly zero? Why or why not? What is the sample standard deviation of the ui?

(iii) Now, generate the yi as

??=1+2??+??≡?0+?1??+??

that is, the population intercept is one and the population slope is two. Use the data to run the regression of yi on xi. What are your estimates of the intercept and slope? Are they equal to the population values in the above equation? Explain.

(iv) Repeat parts (i), (ii), and (iii) with a new sample of data, starting with generating the xi

??=0.5×??

Now what do you obtain for b0 and b1? Why are these different from what you obtained in part (iii)? Explain why in detail.
