Answer:
100 or so atoms of the periodic table, in different combinations, make up Compounds.
Explanation:
Atoms from different element in the periodic table combined together with the help of bond and make a new product that is called compound.
For example
Hydrogen and oxygen are the elements of the periodic table. When one atom of oxygen and two atoms of hydrogen are combined together, a compound will be formed named as water (H20).
In another example, two atoms of oxygen and one atom of carbon combines toghther through chemical reaction and make compund named as Carbon dioxide (CO2).
Consider the following method intended to modify the parameter names by removing all instances of the String n.
public static void removeNames (ArrayList names, String n) { for (/* Missing Code */) { if (names.get(i).equals(n)) { names.remove(i); } } }
Which of the following could correctly replace /* Missing Code */ so that removeNames works as intended?
int i = 0; i < names.size(); i--
int i = names.size() - 1; i >= 9; i++
int i = 0; i < names.size(); i++
int i = names.size() - 1; i >=0; i--
none of the above. The code has an error.
Replace the missing code with 'int i = names.size() - 1; i >=0; i--' to correctly iterate backwards through the ArrayList, preventing skipping elements after removals.
Explanation:The correct code to replace /* Missing Code */ is int i = names.size() - 1; i >=0; i--. This is because we need to iterate backwards through the list to avoid skipping elements after removing one. If we iterate forwards and remove an element, the next element will shift to the position we just removed, and the loop will skip it when i increments. By iterating backwards, we ensure that after an element is removed, it does not affect the iteration since we are moving to previous elements that have already been checked.
Final answer:
The correct iteration pattern for removing elements from an ArrayList without skipping any elements is to iterate backwards. The iteration syntax 'int i = names.size() - 1; i >=0; i--' allows the method to function as intended.
Explanation:
The correct code to replace /* Missing Code */ in the removeNames method should allow the removal of all instances of a specific String n from the ArrayList names. To achieve this, the iteration should go backwards through the ArrayList to avoid skipping elements after removal. Therefore, the correct replacement is:
int i = names.size() - 1; i >=0; i--
When you remove an item from an ArrayList while iterating forward, the next item shifts into the current index, which your loop just passed over, potentially causing you to miss elements. By iterating backwards, you can ensure that the removal of an item does not affect the items you've not yet checked.
People use a computer connected to the internet to manage financial accounts
Answer:
No however, if financial accounts are on website, then that is done, however, not on public network.
Explanation:
This should not be done on the public network, or some other computer. And in general its no. However, if the internet is required, then this must only be done on a private network and under strict firewall rules. Do not ever use the VPN for this as well, as your information can be leaked. You need to do all this, as these are monetary usage, and at times it can be very heavy, and result in very heavy loss. However, this is especially required by small children who use bank accounts regularly. They and all should keep this in mind.
Jason is computer professional who has access to sensitive information. He shares this information with another organization in the same industry. Which professional code of conduct did Jason violate?
Jason violated the confidentiality of information.
Part of information security is "confidentiality of information" wherein an employee must kept all the information he may acquire when he is working in a company, confidential. When we say confidential, he is not allowed to disclose anything that he may know about company's operation, sensitive information to anybody who is outside the company (like in the example, another organization). Because data that he might disclose may get on hands by company's competitors and it can be used against the company. They might steal ideas and strategies.

A python script to print fibonacci series first 20 elements
Answer:
nterms =20
# first two terms
n1, n2 = 0, 1
count = 0
# check if the number of terms is valid
if nterms <= 0:
print("Please enter a positive integer")
elif nterms == 1:
print("Fibonacci sequence upto",nterms,":")
print(n1)
else:
print("Fibonacci sequence:")
while count < nterms:
print(n1)
nth = n1 + n2
# update values
n1 = n2
n2 = nth
count += 1
Explanation:
Here, we store the number of terms in nterms. We initialize the first term to 0 and the second term to 1.
If the number of terms is more than 2, we use a while loop to find the next term in the sequence by adding the preceding two terms. We then interchange the variables (update it) and continue on with the process.
output:
Fibonacci sequence:
0
1
1
2
3
5
8
Final answer:
To print the first 20 elements of the Fibonacci series in Python, a function can be used which iterates through a specified number of elements, updating and printing the next number in the sequence in each step.
Explanation:
The Fibonacci series is a sequence where each number is the sum of the two preceding ones, usually starting with 0 and 1. To print the first 20 elements of the Fibonacci sequence in Python, you can use the following script:
fibonacci.py
def fibonacci(n):
a, b = 0, 1
for _ in range(n):
print(a, end=' ')
a, b = b, a + b
fibonacci(20)
This script uses a simple loop to generate the series and prints out each element. The variables a and b start with values 0 and 1, which are the first two numbers in the Fibonacci sequence. Each iteration of the loop updates the values of 'a' and 'b' to the next two numbers in the sequence, and 'a' is printed out each time. Running this script will output the first 20 numbers of the Fibonacci series.
What is the decimal representation of the following signed binary numbers?
10000000
11001100
10110111
Answer:
(10000000)₂ = -128 in decimal
(11001100)₂ = -52 in decimal
(10110111)₂ = -73 in decimal
Explanation:
NOTE: If Most Significant Bit is 0, it is positive number and if MSB is 1, it is negative number. If number is positive we can simply convert it to decimal. But if number is negative, follow following formula:
(complement of the number) +1EXAMPLE 1
(10000000)₂
(01 1 1 1 1 1 1)₂ ↔ complement of the number
+ 1
(10000000)₂ = 1 ×[tex]2^{7}[/tex]= 128 (magnitude in decimal)
But we remember MSB was 1 so answer is -128.
EXAMPLE 2
(1 1 0 0 1 1 00)₂
(0 0 1 1 0 0 1 1)₂
+ 1
(0 0 1 1 0 1 0 0)₂ = 52 (magnitude in decimal)
But we remember MSB was 1 so answer is -52.
EXAMPLE 3
(1 0 1 1 0 1 1 1)₂
(0 1 00 1 000)₂
+ 1
(01 00 1 00 1)₂ = 73 (magnitude in decimal)
But we remember MSB was 1 so answer is -73.
To convert signed binary numbers to their decimal representation, check if the first bit is 1 (indicating a negative number) and then find the two's complement of the rest of the bits. After converting the two's complement to decimal, prefix the number with a negative sign. For example, 10000000 represents -128, 11001100 represents -52, and 10110111 represents -73 in decimal.
Explanation:The question asks about converting signed binary numbers into their decimal representations. Signed binary numbers use the leftmost bit as a sign indicator, where 0 usually means positive and 1 means negative. To convert them into decimals, one must understand two's complement notation, which is a method used to represent negative binary numbers.
Steps for converting signed binary numbers to decimal:
Check the first bit (most significant bit). If it is 0, the number is positive. If it is 1, the number is negative and you will proceed with finding the two's complement of the rest of the bits.To find the two's complement, invert all the bits (change 1s to 0s and vice versa) and then add 1 to the least significant bit.Convert the resulting binary number to a decimal number.If the original most significant bit was 1, prefix the result with a negative sign to show it is a negative decimal number.Following these steps:
10000000: This represents -128 in decimal as it is the two's complement of 128 (the most significant 1 indicates a negative number).11001100: The first bit is 1, so this is a negative number. Its two's complement is 00110100, which is 52 in decimal, thus the original number is -52.10110111: The first bit is 1, so this is a negative number. Its two's complement is 01001001, which is 73 in decimal, thus the original number is -73.26. Give two properties of softwood

Nicole wants to create a database to collect information about videos in her video rental store. She would like to use the database to look up movies by rating, actors, producer, and title. She would also like to retrieve the movies that are in stock. What fields should she have in her database? title, rating, actor, and producer rating, director, and actor title, rating, actor 1, actor 2, actor 2, actor 4, producer, and in stock product number, price, and rating
Final answer:
Nicole's video rental store database should have fields for title, rating, actors, producer, director, and in stock status to effectively manage her inventory and allow customers to search for movies by various attributes.
Explanation:
Nicole should have the following fields in her database to collect information about videos in her video rental store: title, rating, actor 1, actor 2, actor 3, actor 4, producer, director, and in stock status. Each field serves a specific purpose; for example, the title is for the name of the movie, rating for age-appropriateness, actors and producer for identifying the cast and production team, director for the individual who oversees the creative aspects of the film, and the in stock status to retrieve the movies that are currently available for rent.
Final answer:
Nicole should create a database for her video rental store with fields for title, rating, actors, producer, and in-stock status, using a structured query language to manage relationships and minimize data redundancy.
Explanation:
Nicole wishes to create a database for her video rental store to manage and retrieve information about her inventory. Considering her requirements, the fields she should include in her database are; title, rating, actors, producer, and in-stock status.
This set of fields will allow her to perform searches based on movie characteristics, such as rating, actors, and producer, as well as check availability. To efficiently store information about actors, which can have a one-to-many relationship with movies, an all-reference table would be beneficial to avoid duplication and to minimize space utilization.
Databases, like the one proposed for Nicole, are highly structured and allow for complex queries using a structured query language. This language creates relationships between different pieces of data, such as linking actors to movies they have starred in.
When setting up her database, Nicole should be mindful of managing data types with one-to-many or many-to-many relationships to reduce data redundancy and improve searchability.
Ultimately, the proper organization of her database will enable Nicole to quickly and efficiently find detailed information about the videos in her store, while also ensuring the database remains manageable and scalable as her collection grows.

C. young people with limited income
D. housewives who wanted to look fashionable
Answer:
The answer is not a it is c
Explanation:
I took the test
The segment of society that introduced the grunge look is:
C. young people with limited income
The grunge look was introduced by young people with limited income. Originating in the Pacific Northwest, particularly Seattle, during the late 1980s and early 1990s, the grunge fashion style was heavily influenced by the grunge music scene. This style was characterized by its casual, unkempt, and thrift-store aesthetic, often featuring flannel shirts, ripped jeans, and worn-out clothing. These fashion choices were partly a reflection of the financial constraints faced by many young people at the time, who shopped at second-hand stores and prioritized comfort and practicality over conventional fashion trends. This anti-fashion statement quickly gained popularity and was embraced by youth culture across the country.

What process can be used to make difficult decisions when faced with a situation in which there is no clear right or wrong answer?
Answer:
You should be crystal clear on what you are expecting. At times, you might sense that you are made-up to and that what you must do. Though, you must not be like that. And then think what is ethically right. In situations when you are not clear, thinking on moral grounds can make the picture clear. Also, preserve in mind that doing roughly is healthier than doing nothing at all. And make a custom to be conclusive as that is the key positively. And if you make a routine like this, then you are certainly going to make the difficult decision faster, and when there is no clear right or wrong answer.
