Modify the statistics program from this chapter so that client programshave more flexibility in computing the mean and/ or standard deviation.Specifically, redesign the library to have the following functions:mean(nums) Returns the mean of numbers in nums.stdDev(nums) Returns the standard deviation of nums.meanStdDev (nums) Returns both the mean and standard deviation of nums.
Answer and Explanation:
Using Javascript:
function mean(nums){
var array_numbers= new array(nums);
var meanofNums= array_numbers.reduce()/array_numbers.length;
Console.log(meanofNums);
}
Function Std(nums){
var OurArray= new Array(nums);
var meanOfnums= mean(nums);
var i;
for(i=0; i<=OurArray.length; i++){
OurArray[i]= OurArray[i]-meanOfnums*OurArray[i]-meanOfnums;
}
var al_stdOfnums= OurArray.reduce()/OurArray.length;
var stdOfnums= Math. sqrt(al_stdOfnums);
Console.log(stdOfnums);
}
function meanStdDev (nums){
mean(nums);
Std(nums);
}
/*From the code above, we have defined functions and used them in the last function definition meanStdDev (nums), making for code reusability. In defining the functions, we have followed the formulas for calculating mean and standard deviations and implemented in that order. Notice how we used a for loop in std(nums) function definition to iterate through the elements of the array nums, squaring each value and reassigning a new value for each element(using index value) in the array. We then added these values in array using reduce method, dividing by array length and square rooting the value using the math object method sqrt().*/

Your knowledge of algorithms helps you obtain an exciting job with the Acme Computer Company, along with a $10,000 signing bonus. You decide to invest this money with the goal of maximizing your return at the end of 10 years. You decide to use the Amalgamated Investment Company to manage your investments. Amalgamated Investments requires you to observe the following rules. It offers n different investments, numbered 1 through n. In each year j , investment i provides a return rate of rij . In other words, if you invest d dollars in investment i in year j , then at the end of year j, you have drij dollars. The return rates are guaranteed, that is, you are given all the return rates for the next 10 years for each investment. You make investment decisions only once per year. At the end of each year, you can leave the money made in the previous year in the same investments, or you can shift money to other investments, by either shifting money between existing investments or moving money to a new investement. If you do not move your money between two consecutive years, you pay a fee of f1 dollars, whereas if you switch your money, you pay a fee of f2 dollars, where f2 > f1.
a) The problem, as stated, allows you to invest your money in multiple investments in each year. Prove that there exists an optimal investment strategy that, in each year, puts all the money into a single investment. (Recall that an optimal investment strategy maximizes the amount of money after 10 years and is not concerned with any other objectives, such as minimizing risk.)
b) Prove that the problem of planning your optimal investment strategy exhibits optimal substructure.
c) Design an algorithm that plans your optimal investment strategy. What is the running time of your algorithm?
d) Suppose that Amalgamated Investments imposed the additional restriction that, at any point, you can have no more than $15,000 in any one investment. Show that the problem of maximizing your income at the end of 10 years no longer exhibits optimal substructure.

Which of the following statements about RAID is correct? Group of answer choices All RAID configurations provide fault tolerance for up to one disk failure A RAID 1 configuration of 4 disks has higher storage capacity than a RAID 0 configuration RAID 5 allows up to two disk failures During a RAID 5 disk failure, read performance is not impacted A RAID 1 configuration of four 1TB disks has a storage capacity of 2TB
Answer:
A RAID 1 configuration of 4 disks has higher storage capacity than a RAID 0 configuration
Explanation:
Redundant Array of Independent Disks(RAID) are multiple physical drives arranged in logical units to provide data redundancy and increased performance. They are
RAID 1 configuration duplicates data storage, albeit of lower performance than RAID 0. Also called disk mirroring because it mirrors data on two or more disks, it provides at least two drives that are used interchangeably or together.
A RAID 1 is the configuration of the 4 disks that has higher storage capacity than a RAID 0 configuration. This option A is correct.
What is the RAID ?The RAID is a redundant array of the inexpensive disks and refers to the storage visualization technology that combines multiple physical disk drives. Its contract with earlies highly reliable mainframe disk drives.
The RAID one needs mini of two physical drives as the data is given simultaneously in two places. These drives are mirror images as ne fails the other can take over.

ou use productivity apps on your iPad tablet device while traveling between client sites. You're concerned that you may lose your iPad while on the road and want to protect the data stored on it from being compromised. Currently, your iPad uses a 4-digit PIN number for a passcode. You want to use a more complex alpha-numeric passcode. You also want all data on the device to be erased if the wrong passcode is entered more than 10 consecutive times. What should you do
Answer:
Enable the Erase data optionDisable the simple passcode optionExplanation:
Most smartphone security experts agree that one way to prevent unauthorized access to one's iPad is to enable the erase data feature. Enabling this feature is believed to allow the possibility of all data on the device to be erased if a wrong passcode is entered after a specified number of times.
Of course, it is also possible to set a complex alphanumeric passcode, however, you'll need to first disable the simple passcode option.

Return a version of the given string, where for every star (*) in the string the star and the chars immediately to its left and right are gone. So "ab*cd" yields "ad" and "ab**cd" also yields "ad". starOut("ab*cd") → "ad" starOut("ab**cd") → "ad" starOut("sm*eilly") → "silly"
Answer:
Explanation:
The following code is written in Java and uses a for loop with a series of IF ELSE statements to check the next and previous characters in a string. Checking to make sure that there are no asterix. If so it adds that character to the String variable output. Which is returned to the user at the end of the method. Two test cases have been created and the output can be seen in the attached image below.

You work for a retail clothing chain whose primary outlets are in shopping malls and are conducting an analysis of your customers and their preferences. You wish to find out if there are any particular activities that your customers engage in, or the types of purchases made in the month before or after purchasing select items from your store. To do this, you will want to use the data mining software you are using to do which of the following?
a. Identify clusters
b. Identify sequences
c. Classify data
d. Identify associations
Answer: Identifying sequences
Explanation:
Since the user wants to know if there are any particular activities that the customers engage in, or the types of purchases made in the month before or after purchasing select items from your store, therefore, the data mining software can be used in identifying sequences.
In this case, the data mining software can't be used in classifying data whether into structured or unstructured data. Furthermore, the identification of clusters and associations aren't the correct answers.
Therefore, the best option is B.

Answer:

Explanation:
A college student borrowed his roommate's notebook computer without permission because he needed to write a term paper that was due the next day. While the computer was sitting open on the student's desk overnight, a water pipe in the ceiling began leaking and water dripped down on the computer, rendering it inoperable. A computer repair service estimated that it would cost $500 to repair all the damaged components. At the time it was damaged, the computer was worth $700. If the roommate sues the student for the damage caused to the computer, what will be the extent of his recovery
Answer: $700
Explanation:
Based on the information given in the question, if the roommate sues the student for the damage caused to the computer, the extent of his recovery will be $700.
In this scenario, the student has committed a conversion as the right of possession of the roommate's computer was interfered with by the student as he took it without the roommate's permission, which later sustained damage that was more than 70% of the computer's value. In such case, the extent of the recovery will be the fair market value which is $700.
write difference between dvd r and dvd ram( Any 3 points or any a little big paraph for test)
Answer:
Following are the differences two the given questions:
Explanation:
DVD-R:
DVD-R is a common DVD recordable media that seems like a conventional DVD, and it can only be used once for writing data or analyzing information many times.It is identical to a regular DVD, however, it can be used to record data like a CD-R. Once a DVD-R is "burned," it cannot be read to anymore.There is a 650 nm range recording, nicknamed "Authoring DVD-R." "DVD-R for general" is another format with protection against duplicating, which records at 635 nm. Whilst DVD-R(a) and DVD-R(g) may read forms of one another, they cannot write formats of each other.DVD-RAM:
This is a technology for optical DVD storage where the information may be read, deleted & written constantly.It offers outstanding integrity of data, preservation, and avoidance of damages that can be used for basic storing data, data preservation, or data backup.Those disc drives can indeed be frequently recorded and deleted, and only compatible with DVD-RAM format devices produced by corporations.10 ICTs that encourage reading...?

On SnapI blocked someone, unblocked them and I want to add them again but I forgot their username. Is there anything I can do? Does snap have a list of like my former friends or people I’ve blocked?
Answer:
There is no list of people you had blocked formerly, however you should have seen their username when unblocking them? That's the only way I can think to find their user. Maybe if you have a friend who knows their username, you can get it that way. Or if you remember just a bit of it or their first/last name, you can try searching that.
