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 the chances of a baby zombie to spawn in full golden armor in MC?
Answer:
Baby Zombies can spawn naturally in the Overworld, but they only have a 5% chance to spawn. The player can also spawn one with a Zombie Spawn Egg. Baby Zombies can also be found riding a Chicken, creating a Chicken Jockey.
Explanation:
It is very unlikely for a baby zombie to appear wearing shiny golden armor.
Why is this so?It is not common for a zombie to appear with armor, and it is even rarer for a baby zombie to wear a full set of golden armor.
The chance of this event happening is different for each version and if any changes have been made to the game. However, in the regular MC with no changes, the chances are usually low.

The program which would help Eva convert a Lisp file into machine code by interpreting only a single line of code at a time is: A. interpreters
Interpreters can be defined as computer software programs that are designed to translate (interpret) a programming language (code) into machine code, especially by interpreting only a single line of code at a time.
Hence, an interpreter executes the instructions that are written in a programming language (code) one after the other (instruction by instruction), before it translate (interpret) the next line of code.
On the other hand, a compiler takes the entire program (code) and interprets them.
In conclusion, an interpreter can help Eva convert a Lisp file into machine code by interpreting only a single line of code at a time.

Which of the following does a secure website use to safeguard transmitted information
Answer:encryption
Explanation:
because you can hack encrypted things well not so easily
Encryption is a secure website used to safeguard transmitted information. The correct option is C.
What is encryption?The process of converting information into a secret code that conceals its true meaning is known as encryption.
Cryptography is the study of information encryption and decryption. In the world of computers, ciphertext refers to encrypted data and plaintext to unencrypted data.
By converting the message's content into a code, encryption serves as a confidentiality tool. Integrity and authenticity are the goals of digital signatures.
They serve to confirm the message's source and show that the content hasn't been altered.
In the process of encryption, ordinary text, such as a text message or email, is scrambled into "cypher text," which is an unintelligible format. Secure websites utilise encryption to protect sent information.
Thus, the correct option is C.
