Write a recursive function sumSquares(num) that given an integer num, returns the sum of squares of numbers from 1 to num. For example: sumSquares(3) should return 1^2 2^2 3^2
Answers
Answer:
Here is the recursive function sumSquares(num) that takes an integer num as parameter and returns the sum of squares of numbers from 1 to num.
def sumSquares(num):
if(num >= 0): # checks if the value of num is less than or equal to 0
if (num==0): #if value of num is 0
return 0 #returns 0 if value of num is 0
else: #if value of num is greater than 0
return sumSquares(num - 1)+ num * num #recursively calls the sumSquares method to return the sum of squares of numbers from 1 to num
else: # if a user enters a negative num
(print("The number if not positive")) #prints this message
exit() # exits after displaying that number if not positive message
#below print statement is used in order to check the working of the function
print(sumSquares(3)) #calls function and passes value 3 for num
Explanation:
The program works as follows:
The function sumSquares(num) that takes an integer num as parameter and returns the sum of squares of numbers from 1 to num
The first if condition checks if value of num is positive. If this condition evaluates to true then the another if statement inside this if statement is executed which checks if the value of num is 0. If this condition evaluates to true then the program returns 0. However if this condition evaluates to false then the else part executes which has the following statement:
return sumSquares(num - 1) + num * num
For example num = 3
so the above recursive statement works as follows:
sumSquares(3-1) + 3 * 3
sumSquares(2) + 9
Note that the sumSquares() method is called again and the value 2 is passed as num. As 2 is greater than 0. So again the recursive statement executes:
sumSquares(2 - 1) + 2 * 2 + 9
sumSquares(1) + 4 + 9
sumSquares(1) + 13
sumSquare() method is called again and the value 1 is passed as num. As 1 is greater than 0. So again the recursive statement executes:
sumSquares(1 - 1) + 1 * 1 + 13
sumSquares(0) + 1 + 13
sumSquares(0) + 14
sumSquare() method is called again and the value 0 is passed as num
As the value of num=0 So the if (num == 0): condition evaluates to true and the statement returns 0 executes which returns 0:
sumSquares(0) + 14
0 + 14
Hence the output is:
14
The screenshot of the program along with its output is attached.

Answers
Answer:
I love Microsoft Excel!
Explanation:
2 - The function that would find the average of a particular range is =AVERAGE(). This is used to find the average of something by calculating the arithmetic mean (or just "mean").
3 - The function that would find the total values within a particular range---or in this case, Column J---you would use the =SUM() function. This will add up all of the values in the range you selected. An example could be that Column X has the values of 5, 6, 12, 45, 3. =SUM(X1:X5) = 71.
4 - The function that would count all values is defined as =COUNT(). An example would be =COUNT(A1:A10).
5 - The function that would count the number of occurrences within a particular range is defined as =COUNTIF(). Within the parentheses, you would put the range of data that you are working with. Then, in quotations, you would put the name or value that you are trying to find.
In your case, it would be =COUNTIF(range,"9") ((I put range in there since I do not know what your range is as it is not defined within the context of this question))

While troubleshooting his computer, you find that his computer is issued an Automatic Private IP Addressing (APIPA) address. All the network equipment in the user's computer is functioning properly because you are able to access the user's computer from a remote computer. What is most likely the problem
Answers
Answer:
the issued Automatic Private IP Addressing (APIPA) address.
Explanation:
Since we are told that the user was able to access the network resources yesterday, and all the network equipment in the user's computer is functioning properly, there is a very high possibility that because the user's computer has been issued an Automatic Private IP Addressing (APIPA) address, it affected his computer's ability to connect to a public network.
This is the case because private network IP addresses are known to prevent inflow and outflow of data onto public networks.

Use a subprogram to input the numbers, a function to find the mean, and a subprogram to output the result. Use a subprogram to Input the numbers, a Function to find the mean and a subprogram to output the Result.

Explanation:
A subprogram may be considered as a method where we pass some values in the arguments and return some value.
The answer is written in python language, where we have used
inputNumber() subprogram to get the input from the user.
function averageCalculator() to calculate the average.
printoutput() subprogram to print the output or the average of the numbers.
Please refer to the attached image for better understanding of the indentation of code.
Now, let us learn about them one by one:
inputNumber(): We get the number of values to be entered as an integer value and then get the numbers as float.
Store the values in a list and return the list to the caller main program.
averageCalculator(l): Contains a list as argument as we got from inputNumber(). It sums all the numbers and divides with total number to find the average. Returns the average value to the caller main program.
printoutput(avg): Contains an argument which is the average calculated in the averageCalculator(). It prints the argument passed to it.

There is a problem while you are trying the calculate the average owls per zoo.

F. TCP 68
Answers
Answer:
B. UDP 67
C. UDP 68
Explanation:
In this scenario, after a new firewall is installed, users report that they do not have connectivity to the Internet. The output of the ipconfig command shows an IP address of 169.254.0.101. The ports that would need to be opened on the firewall to allow the users to obtain an IP address are both the UDP 67 and UDP 68. UDP is an acronym for user datagram protocol in computer networking and it is part of the transmission control protocol/internet protocol (TCP/IP) suite.
Generally, the standard Internet communications protocols which allow digital computers to transfer (prepare and forward) data over long distances is the TCP/IP suite.
Also, the UDP 67 and 68 ports is responsible for the connectionless framework which is typically being used by the dynamic host configuration protocol (DHCP) that is used to assign IP addresses to various computer users and manage their leases.
UDP 67 is the destination port for a DHCP server while the UDP 68 is the port number for the computer user (client).
Hence, for the users to have access to the internet or internet connectivity both UDP 67 and 68 must be opened on the firewall.

When we add another bit, the amount of numbers we can make multiplies by 2. So a two-bit number can make 4 numbers, but a three-bit number can make 8.

The bit is the most basic unit for storing information. Bits can either be represented as either 0 or 1. Data is represented by using this multiple bits.
