In 2004 astronomers reported the discovery of a large Jupiter-sized planet orbiting very close to the star HD 179949 (hence the term "hot Jupiter"). The orbit was just 19 the distance of Mercury from our sun, and it takes the planet only 3.09 days to make one orbit (assumed to be circular).

What is the mass of the star in kilograms?

(b) as a multiple of our sun's mass.

(c) How fast (in km/s) is this planet moving?

How can you predict industry changes using supply and demand? Elaborate. What are the sources of Economic Profit? Looking for some original content.

In a double linked chain, each node can point to the previous node as well as the next node.:

a. Define a class to represent a node in a doubly linked chain (UML)

b. Define a class to represent the doubly linked chain (UML), with operations such as:

1. finding its length.

2. add a new Node to the end of the chain.

3. check whether a given Node is included in the Chain (search a node)

4. another operation of your choice.

c. illustrate and list the steps to add to a node to the beginning of the doubly linked chain.

d. illustrate and list the steps necessary to remove the first noe from the doubly linked chain.

Jeeler​'s Netballs is a manufacturer of​ high-quality basketballs and volleyballs. Setup costs are driven by the number of batches. Equipment and maintenance costs increase with the number of​ machine-hours, and lease rent is paid per square foot. Capacity of the facility is 14,000 square​ feet, and Jeeler is using only 80​% of this capacity. Jeeler records the cost of unused capacity as a separate line item and not as a product cost. The following is the budgeted information for Jeeler​:

Other budget information​ follows:

1.Calculate the budgeted cost per unit of cost driver for each indirect cost pool.

2.What is the budgeted cost of unused​ capacity?

3.What is the budgeted total cost and the cost per unit of resources used to produce​ (a) basketballs and​ (b) volleyballs?

4.Why might excess capacity be beneficial for JeelerJeeler​? What are some of the issues JeelerJeeler should consider before increasing production to use the​ space?

a. You are conducting a lab experiment on the promoter regions of genes. In one experiment you apply heat to two sections of DNA that you believe could be promoter regions. One region unwinds at 80 degrees C and the other unwinds at 60 degrees C. Which of the two strands contain the promoter? Explain.

b. Apply your knowledge of genetics to explain what would happen in a nucleus if histones were negatively charged.

There's a fine line between white-hat and gray-hat hackers and between gray-hats and black-hats. For instance, some experts consider gray-hat hackers an essential part of securing the Internet because they often expose vulnerabilities before they're discovered by the security community. Research the "definitions" of each of these types of hackers and answer the following questions.

1. What is hacking?
2. At what point does hacking become illegal?
3. Give a specific, real-world example of when good was done by any form of hacking?
4. Give a specific, real-world example of when harm was done by any form of hacking?
5. Provide three (3) ways to protect yourself and your computing devices from hackers.

1)Lets do a simple bayesian calculation.

60% of frogs are female, the rest male.

All male frogs sing, but only 10% of female frogs sing.

You hear a frog singing.

What is the posterior probability that this singing frog is male?

(hint! The probability of any frog singing is the probability  of a singing female (.6 x .1) plus that of a singing male (.4 x 1))

1)23%

2)35%

3)75%

4)87%

2)Which is the most complicated model for molecular sequence evolution?  

1)Jukes Cantor

2)F81

3)HKY

4)GTR

3)You run modeltest on your data and determine that you do not have equal frequencies of bases, but you don't see any evidence that transversions are any more or less common than translations. Which model should you use?

1)JC

2)F81

3)HKY

4)GTR

4)The support values on trees generated via bayesian methods convey:

1)How likely that clade is

2)What proportion of trees that are likely to come from the provided data contain the clade in question

3)How many substitions are found in the sequences between two taxa

4)The quality of the analysis

For a particular redox reaction, ClO−2 is oxidized to ClO−4 and Fe3+ is reduced to Fe2+. Complete and balance the equation for this reaction in basic solution. Phases are optional.

A columnist for Forbes argues, "Even if China is always better than Spain at producing textiles, if the best thing that Spain could be doing is textiles, then that's what Spain should be doing".

a. What does the columnist mean by "China is always better than Spain" in the production of textiles (which include clothing, sheets, and similar products)? Was the columnist arguing that China has an absolute advantage over Spain in producing textiles, a comparative advantage, or both? Briefly explain with full sentences.

b. The columnist noted that, in fact, Spain exports significant quantities of textiles. If this description of the situation in China and Spain is accurate, briefly explain how Spanish firms are able to export textiles in competition with Chinese firms.

please explain thank you

A 5.00 kg block is moving at 3.00 m/s along a frictionless table and collides with a 2.00 kg block that is initially at rest. The two blocks stick together and then slide up a 20.0 ◦ frictionless inclined plane. What is the maximum distance the two blocks slide up the incline?

Offer an example of a strategic commitment you know of or that you believe would be beneficial to a firm in an industry. Explain why the commitment is irreversible, understandable and credible and give an indication of the position (tough or soft) it forces the firm into. Your discussion should make it clear why this move would be beneficial to the firm. Alternatively, your example may be of a strategic move that backfired. In this case, you should similarly describe the actions that constituted the commitment and explain why the commitment failed.

The Stellar Inc., a manufacturer of low-sugar, low-sodium, low-cholesterol TV dinners, would like to increase its market share in the Sunbelt. In order to do so, Stellar has decided to locate a new factory in the Panama City area. Stellar will either buy or lease a site depending upon which is more advantageous. The site location committee has narrowed down the available sites to the following three very similar buildings that will meet their needs.

Building A: Purchase for a cash price of $618,100, useful life 26 years.

Building B: Lease for 26 years with annual lease payments of $70,340 being made at the beginning of the year.

Building C: Purchase for $653,200 cash. This building is larger than needed; however, the excess space can be sublet for 26 years at a net annual rental of $6,540. Rental payments will be received at the end of each year. The Stellar Inc. has no aversion to being a landlord.
