In its latest press release, Pill International announced that they are working on a new drug that would stunt the deterioration of brain cells in Alzheimer's patients. If successful, the drug could prolong the life of patients and allow them to retain their basic mobility.

The R&D team is currently testing the drug, which comes in the form of a digestible tablet, for its ability to be dissolved and absorbed in the bloodstream. Based on their latest experiments, they have learned that there is a relationship between the amount of time that the tablet's powder spends in the tray dryer and the amount of time it takes to get dissolved (Y). As a member of this research team, you have been asked to establish the relationship between the two variables and to predict potential dissolution times based on the time spent in the dryer.

The following data represent the level of health and the level of education for a random sample of 1630 residents.

Hello. Please answer the following two-part question in Scheme. Not Python, not any form of C, but in the language Scheme. If you do not know Scheme, please do not answer the question. I've had to upload it multiple times now. Thank you.

2.1 Write a recursive function called eval-poly that takes a list of numbers representing the coefficients of a polynomial and a value for ? and evaluates the polynomial for the given value of ?. The list of coefficients should start with the term of lowest degree and end with the term of highest degree. If any term of intermediate degree is missing from the polynomial it should have a coefficient of zero. For example, the polynomial ?3+4?2+2 would be represented by the list '(2 0 4 1). Hint: the polynomial above can be rewritten as 2+?⋅(0+?⋅(4+?⋅1))

> (eval-poly '(5) 0)

> (eval-poly '(4 3) 2)

10

> (eval-poly '(2 7 1) 3)

2.2 Write a tail-recursive version of the previous problem called eval-poly-tail. It should call a helper function called eval-poly-tail-helper that uses tail recursion to keep a running sum of the terms evaluated so far. You might want to use the expt function to take a number to a power.

Edit: If you can't answer my question then move along to allow someone who can to do so. Thanks.

3.1 Write a recursive function called split that takes a list and returns a list containing two lists, each of which has roughly half the items in the original list. The easiest way to do this is to alternate items between the two lists, so that (split '(1 2 3 4 5)) would return '((1 3 5) (2 4)). I recommend using two base cases: one for an empty list and the other for a list containing one item.
> (split '())

(() ())

> (split '(3))

((3) ())

> (split '(4 8))

((4) (8))

> (split '(8 6 7 5 3 0 9))

((8 7 3 9) (6 5 0))

3.2 Write a recursive function called merge that takes two sorted lists of numbers and merges them together into one sorted list containing all of the number in both lists including duplicates.
> (merge '() '())

> (merge '() '(1 2 3))

(1 2 3)

You must evaluate the purchase of a proposed spectrometer for the R&D department. The base price is $70,000, and it would cost another $14,000 to modify the equipment for special use by the firm. The equipment falls into the MACRS 3-year class and would be sold after 3 years for $35,000. The applicable depreciation rates are 33%, 45%, 15%, and 7%. The equipment would require an $6,000 increase in net operating working capital (spare parts inventory). The project would have no effect on revenues, but it should save the firm $66,000 per year in before-tax labor costs. The firm's marginal federal-plus-state tax rate is 35%.

Case- IT Auditing

The SSO Server is a single purpose server solely designed for SSO and resides in the internal network. Using a batch process, the vendor provides quarterly updates which are downloaded directly to the server and automatically installed by the server’s single purpose operating system. Access to the SSO application is restricted to the security administration staff. The vendor maintains an active account on the server in the event maintenance is required. The vendor accesses the system periodically to review status and log activity to determine the server’s capacity and to proactively look for concerns prior to problems arising. A replication copy of the SSO Server exists as a backup and automatically assumes primary role if the main server stops functioning.
