Answers

Answer: share information and collaborate with a select group of outside organizations or individuals.

Explanation:

When a company uses an intranet, it is for the purpose of sharing information within the company so in the same vein, an extranet is done to share information with entities outside the company be it people or organizations.

For information to be shared, the other companies and organizations need to have the means and authorization to join the extranet. Extranets are very useful as they enable collaboration across vast distances thereby increasing productivity.

The most likely reason a firm would decide to establish an extranet is B. share information and collaborate with a select group of outside organizations or individuals.

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.

Answers

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().*/

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

Answers

Answer:

Enable the Erase data optionDisable the simple passcode option

Explanation:

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.

What is binary number system? Why is it used in computer system?

Answers

Answer:

Computers depend mainly on binary because it’s more time efficient for them to so.

Explanation:

It’s easier to identify 0 as “off” and 1 as “on”. As you may know, transistors are the fundamental blocks of microprocessors and ICs. The reasons this is the case is that these transistors form logic gates which can carry out basic logic operations. These logic gates are a huge step into making microprocessors/ICs/etc. And what do these logic gates depend on? They depend on binary.

Whoa whoa, wait a minute. Let’s first take a step back to know a thing or two about logic gates.

These logic gate can be constructed from transistors. They carry basic logic operations. You have one or more inputs “entering” the logic gate ——-> A certain operation is performed on them ——-> you get your output. The input is a voltage. This voltage it can be interpreted as an “on” or “off” according to the gate. Once again these offs and ons are 0s and 1s. For example the Inverter/NOT gate is a gate that simply takes an input and gives its inverse. For example:-

A low voltage/an “off” signal/ a “0” “enters” the NOT gate. ——-> A high voltage/an “on” signal/ a “1” is the result of the operation performed

(In the above example low voltage = “off” signal = 0, high voltage = “on” signal = 1)

As you can see, a 0 enters the NOT gate and a 1 comes out or vice versa. Now, if you were a logic gate, you’d prefer working with just 0s and 1s right? I would. This would be much easier to work with than a lot of different values.

It’s a herculean task to work with these though as a human. And fortunately, programming languages exist for giving the computer instructions to do in a “language” other than its own.

Answers

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.

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.
