The mean of a sequence of n numbers is m. If we split the sequence into two sequences of lengths n1 and n2 and compute their means m1 and m2, which of the following is TRUE?
The mean of a sequence of n numbers is m. If we split the sequence into two sequences of lengths n1 and n2 and compute their means m1 and m2, which of the following is TRUE?
The mean of a sequence of numbers is the average.
The true statement is: [tex]\mathbf{mn = m_1n_1 + m_2n_2}[/tex]
The given parameters are:
[tex]\mathbf{Mean=m}[/tex]
[tex]\mathbf{Size=n}[/tex]
The mean of a dataset is calculated as:
[tex]\mathbf{Mean = \frac{Sum}{Count}}[/tex]
So, we have:
[tex]\mathbf{m = \frac{Sum}{n}}[/tex]
Multiply both sides by m
[tex]\mathbf{Sum = mn}[/tex]
When the sequence is split into two, we have:
[tex]\mathbf{\sum x_1 = m_1n_1}[/tex]
[tex]\mathbf{\sum x_2 = m_2n_2}[/tex]
Where:
[tex]\mathbf{Sum = \sum x_1 + \sum x_2}[/tex]
So, we have:
[tex]\mathbf{mn = m_1n_1 + m_2n_2}[/tex]
Hence, the true statement is: [tex]\mathbf{mn = m_1n_1 + m_2n_2}[/tex]

What are sustainable practices?Sustainable practices are the approach that uses technology with respect to the protection of the environment. The social, economic, and environmental balances are established when sustainable computational technologies are implemented.
This practice allows the client to spread the centers and applications globally on a large scale and can be accomplished by building the software once and should avoid redeveloping.
Therefore, to distribute the energy the data centers must be established.

Steve Jobs
Born
Feburary 24, 1955
Death
October 5, 20122
Steven Paul Jobs was an American inventor, designer and entrepreneur who was the co-founder, chief executive and chairman of
Apple Computer.
Apple's revolutionary products, which include the
In 1976, when Jobs was just 21, he and Wozniak started Apple Computer in the Jobs’ family garage. They funded their entrepreneurial
venture by Jobs selling his Volkswagen bus and Wozniak selling his beloved scientific calculator. Jobs and Wozniak are credited with
revolutionizing the computer industry with Apple by democratizing the technology and making machines smaller, cheaper, intuitive and
accessible to everyday consumers.
Wozniak conceived of a series of user-friendly personal computers, and — with Jobs in charge of marketing — Apple initially marketed
the computers for $666.66 each. The Apple I earned the corporation around $774,000. Three years after the release of Apple's second
model, the Apple II, the company's sales increased by 700 percent to $139 million.
In 1980, Apple Computer became a publicly-traded company, with a market value of $1.2 billion by the end of its very first day of
trading. Jobs looked to marketing expert John Sculley of Pepsi-Cola to take over the role of CEO for Apple.
The next several products from Apple suffered significant design flaws, however, resulting in recalls and consumer disappointment.
IBM suddenly surpassed Apple in sales, and Apple had to compete with an IBM/PC-dominated business world.
In 1984, Apple released the Macintosh, marketing the computer as a piece of a counterculture lifestyle: romantic, youthful,
creative. But despite positive sales and performance superior to IBM's PCs, the Macintosh was still not IBM-compatible.
Sculley believed Jobs was hurting Apple, and the company's executives began to phase him out. Not actually having had an
official title with the company he co-founded, Jobs was pushed into a more marginalized position and thus left Apple in 1985.

The analyst wants to combine the two columns into a single column named location, with the city and state separated by a comma. What code chunk lets the analyst create the location column
The programing language, R has a unite unite function in the tidyr package. Hence, the code chunk which let's the analyst create the location column is; unite (stores, "location”, city, state, sep=",")
The syntax for the unite function is ; unite(data,col,..., sep)data = dataframe from which data is to be extracted `; stores col = name of the new column ;" location"... = dataframes to be merged ; city, statesep = seperator ; ","Hence, the required syntax goes thus :

Suppose you are in charge of unloading containers from ships arriving at a port onto trucks. A ship arrives with n containers of weight w1, w2, . . . , wn tons. Standing on the dock is a set of trucks, each of which can hold 1 ton of weight. (You can assume that none of the containers weighs more than 1 ton, since in this case you would not be able to transport it.) You can stack multiple containers in each truck subject to the weight restriction of 1 ton. Hoping to minimize your truck rental expenses, you aim to minimize the number of trucks needed in order to carry all the containers.
You start with the following greedy strategy. Start with an empty truck and begin loading containers 1, 2, 3, ... onto it until you get to a container that would overflow the weight limit. Now, declare this truck "loaded" and send it off; then continue the process with a fresh truck. After trying (and failing) to prove that this greedy algorithm is optimal, you decide to attempt to come up with a counter-example to see if you can discover that your strategy is not optimal.
Required:
Provide an example of a set of weights for which your algorithm does not use the minimum possible number of trucks.

It should be noted that the process of redefining the functionality of a built-in operator to operate is known as operator overloading.
Operator overloading simply means polymorphism. It's a manner in which the operating system allows the same operator name to be used for different operations.
Operator overloading allows the operator symbols to be bound to more than one implementation. It's vital in redefining the functionality of a built-in operator to operate on programmer-defined objects.
