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]

The most popular workbooks are:
"MS Excel" and "G-Sheets"The purposes of this question we will consider both.
Columns in either of the two types of worksheets mentioned above refer to the Vertical Grids which run through the sheets.
Rows on the other hand refer to the Horizontal Grids which run through the sheets. Both Columns and Rows comprise Cells.
Freezing in this sense refers to the act of ensuring that regardless of which direction the worksheet is scrolled, the frozen parts remain visible on the screen.

Answer:
Perfection: When you make a mistake, no one cares but you.
Even the most accomplished public speaker will make a mistake at some point. Just keep in mind that you’ll notice more than anyone in your audience. The most important thing you can do after making a mistake during a presentation is to keep going. Don’t stop and—unless the mistake was truly earth shattering—never apologize to the audience for a minor slip. Unless they are reading the speech during your delivery, the audience won’t know if you left out a word, said the wrong name, or skipped a page. Because “to err is human,” a mistake can work for you, because it allows you to connect with your audience. People don’t want to hear from someone who is “perfect;” they will relate much more easily to someone who is real.
Master the art of public speaking and crush your next presentation with one of our public speaking seminars, available online and in a classic classroom format.
Effective Executive Speaking
Take your public speaking to the next level! Speak, present and communicate with poise, power and persuasion.
Visualization: If you can see it, you can speak it.
Winners in all aspects of life have this in common: they practice visualization to achieve their goals. Sales people envision themselves closing the deal; executives picture themselves developing new ventures; athletes close their eyes and imagine themselves making that basket, hitting that home run, or breaking that record.
The same is true in public speaking. If you’ve read “10 Powerful Body Language Tips” then you know how anxiety can impact presentation skills. The best way to fight anxiety and to become a more comfortable speaker is to practice in the one place where no one else can see you—your mind. If you visualize on a consistent basis, you’ll prepare your mind for the prospect of speaking in public, and pretty soon you’ll conquer any feelings of anxiety.
Discipline: Practice makes perfectly good.
Your goal is not to be a perfect public speaker. There is no such thing. Your goal is to be an effective public speaker. Like anything else in life, it takes practice to improve those public speaking skills. We too often take communication for granted because we speak to people everyday. But when your prosperity is directly linked to how well you perform in front a group, you need to give the task the same attention as if you were a professional athlete. Remember, even world champion athletes practice every day. Try taking a class where you practice giving speeches.
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.

Explanation:
The input nums is supposed to be an array of unique integers ranging from 1 to nums.length (inclusive). However, there is a mistake: one of the numbers in the array is duplicated, which means another number is missing. Find and return the sum of the duplicated number and the missing number. Example: in the array [4, 3, 3, 1], 3 is present twice and 2 is missing, so 3 2
The program is an illustration of loops.
Loops are used to perform repetitive and iterative operations.
The program in Python where comments are used to explain each line is as follows:
#This intializes the list
nums = [5,4,4,2,1]
#This gets the length of the list
size = len(nums)
#This iterates through the list
for i in range(size):
#The following if condition determines the repeating number
if nums[abs(nums[i])-1] > 0:
nums[abs(nums[i])-1] = -nums[abs(nums[i])-1]
else:
repeating = abs(nums[i])
#The following if condition determines the missing number
if nums[i]>0:
missing = i + 1
#This calculates and prints the sum of the missing and the repeating numbers
print(repeating+missing)

1. Give one reason why data is represented in binary in a computer [1]
2. How many bits in a byte? [1]
3. How many bytes are there in a MB? Include your working.
Answer:
1) Computers use voltages and since voltages changes often, no specific voltage is set for each number in the decimal system. For this reason, binary is measured as a two-state system i.e. on or off. Also, to keep calculations simple and convert into binary online, computers use the binary number system
2) 8 bits
3) 1000000 bytes
calculate the speed when given the amount of 1TB to be transfer in 5hrs.
Answer:
Data transfer rate is the speed that a certain amount of data is transferred over a given period of time. You might want to know the transfer rate if you’re downloading something online or transferring data from one source to another. First, convert your units so the file size and transfer speed are in either bits or bytes with the same prefix (kilo, mega, giga, or tera). Then, plug your numbers into the equation S = A ÷ T in which A is the amount of data and T is the transfer time to solve for S, the speed, or rate, of transfer. You can also determine the amount of data or the transfer time if you know one of the variables plus the speed of transfer.
