ABC Daily is a local newspaper company. They have provided both printed newspaper and online news feed for their customer. The chief editor would like to use the latest technologies to upgrade the online news feed system. He just heard about the speech recognition and he is interested to know more about the technology.

(a) Define speech recognition and list THREE potential applications of the technologies

(b) If ABC Daily use speech recognition to automatically create online news feed in real time, what are the possible problems or challenges in using the technology?

(c) Suggest TWO ways to provide news service for the visually impaired in reading ABC Daily

White Mountain Technology is evaluating a project that would require the purchase of a piece of equipment for 660,000 dollars today. During year 1, the project is expected to have relevant revenue of 925,600 dollars, relevant costs of 291,800 dollars, and relevant depreciation of 93,700 dollars. White Mountain Technology would need to borrow 660,000 today for the equipment and would need to make an interest payment of 29,800 dollars to the bank in 1 year. Relevant operating cash flow for the project in year 1 is expected to be 345,495 dollars. What is the tax rate expected to be in year 1? Answer as a rate in decimal format so that 12.34% would be entered as .1234 and 0.98% would be entered as .0098.

A company is considering purchasing a new technology that requires an initial capital

investment of $9,000. Annual revenues from the technology are predicted to be $6,500, and

annual expenses will be $4,000. The equipment has an estimated life of 11 years, at which time

the salvage value is expected to be $1,000. The MARR for the company is 15%.

a. Using the annual worth (AW) method, determine whether purchasing the equipment is

economically justified.

b. Repeat part (a) using the internal rate of return (IRR) method.

c. Using the present worth (PW) method, determine the break-even time period after which

purchase of the equipment generates a profit. (Find N when PW = 0)

A pediatrician wants to determine the relation that may exist between a​ child's height and head circumference. She randomly selects 5 children and measures their height and head circumference. The data are summarized below. Complete parts​ (a) through​ (f) below.

(a) Treating height as the explanatory variable, X, use technology to determine the estimates of β0 and β1.

β0 ≈b0 = ____ ​(Round to two decimal places as​ needed.)

β1 ≈b1 = ____ (Round to two decimal places as​ needed.)

​(b) Use technology to compute the standard of the estimate , se.

se= ______ ( Rounding to four decimal places)

​(c)  A normal probability plot suggests that the residuals are normally distributed . Use technology to determine sb1 .

Sb1= _____ ( Rounding to four decimal places)

(d) ​A normal probability plot suggests that the residuals are normally distributed. Test whether a linear relation exists between height and head circumference at the α=0.01 level of significance.

The first step is to set up a hypothesis test. The parameter being tested is the​ slope, β1​, of the linear regression line. If there is no linear relation between the response and explanatory​ variables, the slope of the true regression line will be zero.

The​ P-value for this test is _____ (rounding to three decimal places.)

(e) Use technology to construct a​ 95% confidence interval about the slope of the true​ least-squares regression line.

Lower bound: ____

Upper bound : _____

(f) Suppose a child has a height of 27 inches. What would be a good guess for the​ child's head​circumference?

Substitute the given​ height, 27​ inches, for x in the regression line and​ simplify, rounding to two decimal places.

Y= ______

Now that we know a bit more about epidemiologic curves and the important steps in an outbreak investigation, let's see how this is playing out with COVID-19.

1. You've probably heard public health officials say that we need to "flatten the curve". What does this statement mean and why is it so important?

2. Discuss one method public health officials have implemented to flatten the COVID-19 curve. Do you think this method is effective? Explain.

3. Will the nation-wide Black Lives Matter demonstrations and protests of police brutality and systemic racism have an impact incidence of COVID-19? Justify your answer.

4. Contact tracing is a critically important component of an outbreak investigation. Briefly explain what contract tracing is and why it is imperative with a disease like COVID-19.

5. For those of you that aren't aware, tech giants, Google and Apple, have designed COVID-19 tracking software and applications for your smartphone. Watch the following video summarizing the technology by the Wall Street Journal: COVID-19 Tracking Software.  By utilizing location services and Bluetooth on your smartphone, these devices are theoretically be able to notify individuals of potential exposure to SARS-CoV-2. Answer questions A-D below:

1. Do you think making use of such technology is a viable means for accomplishing contact tracing?
2. Outline one positive aspect of this type of technology.
3. Outline one negative aspect of this type of technology.
4. Do you think this is a violation of privacy? Like "big brother" is watching your every move? Justify your answer.

1 a). Write down the Slater determinant for Lithium. Expand the determinant into linear combination of products.

b). Write down the Slater determinant for Beryllium. Expand the determinant into linear combination of products.

1. A uniform cylinder of mass m and radius r is rolling down a slope of inclination 30°. The cylinder rolls without slipping. At what rate does the cylinder accelerate down the slope?

Down Syndrome can be caused by trisomy 21 or by a Robertsonian translocation. Explain specifically how each of these mutations can happen in the cell, and why both cause the symptoms of Down Syndrome.
