To return the value of the cell D8, the formula should be OFFSETA1=________.
Answer:
The formula is =OFFSET( A1, 7,3,1,1 )
Explanation:
Microsoft excel is a statistical and analytical tool for data management and analysis. Its working environment is called a worksheet. The worksheets are made up of rows and columns also known as records and fields respectively.
Functions like OFFSET in excel is used to return a cell or group of cells. It gets the position to turn by start getting a starting port, then the number of records below it and the fields after, then the length and width of cells to return.
syntax: =OFFSET( "starting cell", "number of rows below", "number of columns after", "height of cells to return", "width of cells to return" )
Write code to assign the number of characters in the string rv to a variable num_chars.
Answer:

Read the following program requirements prior to completing the Hands-on. A retail company must file a monthly sales tax report listing the total sales for the month and the amount of state and county sales tax collected. The state sales tax rate is 4 percent and the county sales tax rate is 2 percent. Write a program that asks the user to enter the total sales for the month. The application should calculate and display the following: • The amount of county sales tax • The amount of state sales tax • The total sales tax (county plus state) Step 1: Write the steps the algorithm:
Answer:
state_sales_tax_rate = 0.04
county_sales_tax_rate = 0.02
sales = float(input("Enter the total sales for the month: "))
county_sales_tax = sales * county_sales_tax_rate
state_sales_tax = sales * state_sales_tax_rate
total_sales_tax = county_sales_tax + state_sales_tax
print("The amount of county sales tax is " + str(county_sales_tax))
print("The amount of state sales tax is " + str(state_sales_tax))
print("The total sales tax is " + str(total_sales_tax))

Although the original BBS system was simple, it increased people's ability to communicate
across multiple lines
across analog lines
with multiple messages
across long distances
Answer:
across long distances.
Explanation:
BBS is an acronym for bulletin board system and it can be defined as an application or computer system which is typically used for the sharing and dissemination of user informations or data such as messages or files over a network. It is generally considered to be an alternative to the world wide web (www) in the 1980s and early 1990s before the advancement of the internet.
Hence, the bulletin board system (BBS) was typically accessed using a Telnet or a dial-up modem.
Although the original BBS system was simple, it increased people's ability to communicate across long distances because users didn't have to be physically present to exchange messages or files.

c. adding more proxy servers.
d. adding more workstations.
Answer:
D. I think
Explanation:
Horizontal scaling of a client/server architecture means adding more workstations. Thus the correct option is D.
What is client/server architecture?A computing model which places the majority of the services and features that the client requests on the server, which also hosts, delivers, and manages them are known as client-server architecture
Most applications that call for a division of labor between the client and the server benefit from the client-server architecture. The accessibility performance of applications is improved.
Both horizontal and vertical scaling is possible for client/server architectures. If a network is scaled vertically, more powerful, faster servers are added to the network, whereas horizontal scaling involves adding additional workstations (clients).
Therefore, option D is appropriate.

During the past decade ocean levels have been rising faster than in the past, an average of approximately 3.1 millimeters per year. Write a program that computes how much ocean levels are expected to rise during the next 15 years if they continue rising at this rate. Display the answer in both centimeters and inches.
Answer:
Program in Python is as follows:
rise = 3.1
for i in range(1,16):
print("Rise in Year "+str(i))
cm = rise * 0.1 * i
inch = rise/25.4 * i
print(str(cm)+" centimetres")
print(str(inch)+" inches")
Explanation:
This line initializes the rise of the ocean level
rise = 3.1
The following iterates from 1 to 15 (which stands for year)
for i in range(1,16):
print("Rise in Year "+str(i))
This calculates the rise in each year in centimetre
cm = rise * 0.1 * i
This calculates the rise in each year in inches
inch = rise/25.4 * i
The line prints calculated ocean rise in centimetres
print(str(cm)+" centimetres")
The line prints calculated ocean rise in inches
print(str(inch)+" inches")
1) Create the following 2D array in one instruction: {{1,2,3,4,5}, {1,2,3,4,5}, {1,2,3,4,5}} // your code goes below:
2) Create the above 2D array using a for loop and the below method: public static int[] simpleArray(int n) { int[] result = new int[n]; for (int i=0; i
Answer:
1)
int[][] a2dArray = {{1,2,3,4,5},{1,2,3,4,5},{1,2,3,4,5}};
2)
public class Main
{
public static void main(String[] args) {
int[][] a2dArray2 = new int[3][5];
for (int i=0; i<3; i++) {
a2dArray2[i] = simpleArray(5);
}
for (int i=0; i<a2dArray2.length; i++) {
for (int j=0; j<a2dArray2[i].length; j++){
System.out.print(a2dArray2[i][j] + "");
}
System.out.println();
}
}
public static int[] simpleArray(int n){
int[] result = new int[n];
for (int i=0; i<n; i++) {
result[i] = i+1;
}
return result;
}
}
Explanation:
1) To create a 2D array you need to write the type, two brackets and the name on the left hand side. Put the values on the right hand side.
2) Declare the array. Since there will be 3 rows and 5 columns, put these values in the brackets on the right hand side.
Create a for loop that iterates 3 times. Call the method simpleArray inside the loop so that each row of the a2dArray2 array will be set. Be aware that simpleArray method takes an integer as parameter and creates a 1D array, the numbers in the array starts from 1 and goes to the parameter value. That is why calling the method simpleArray (with parameter 5) 3 times will create a 2D array that has 3 rows and 5 columns.
Then, use a nested for loop to display the 2D array.
