Answer:
A. downward-sloping at first but then upward-sloping
Explanation:
The long-run average cost curve is typical "downward-sloping at first but then upward-sloping." This can be shown as the long-run average cost curve is graphically represented in a U shape.
The reason is that the long-run average cost of production initially falls as a result of increase returns to scale as output is increased, however, at some stage beyond this certain this, the long-run average cost of production rises because of decreasing returns of scale.
Write a Python program string_functions.py that defines several functions. Each function re-implements Python's built-in string methods.1. my_compare(str1, str2): Takes two strings as parameters (str1, str2) and returns a -1 if str1 is alphabetically less than str2, returns a 0 if str1 is alphabetically equal to str2, and returns a 1 if str1 is alphabetically greater than str2. 2. is_char_in(string, char): Takes a string and a character as parameters and returns True if the character is in the string or False if it is not.3. is_char_not_in(string, char): Takes a string and a character as parameters and returns True if the character is NOT in the string or False if it is.4. my_count(string, char): Takes a string and a character as parameters and returns an integer count for each occurrence of the character. For example, if the function takes in 'abracadabra' and 'a', the function should return 5.5. my_endswith(string, char): Takes a string and a character as parameters and returns True if the character is the last character in the string or False if it is not. For example, if the function takes in 'quartz' and 'z', the function should return True. If the function takes in 'quartz' and 'q', the function should return False.6. my_find(string, char): Takes a string and a character as parameters and returns the first index from the left where the character is found. If it does not find the character, return -1. For example, if the function takes in ‘programming’ and ‘g’, it should return 3. Do not use str.find() for this.7. my_replace(string, char1, char2): Takes a string and two characters (char1 and char2) as parameters and returns a string with all occurrences of char1 replaced by char2. For example, if the string is ‘bamboozle’ and char1 is ‘b’ and char2 is ‘t’ then your function should return ‘tamtoozle’.8. my_upper(string): Takes a string as a parameter and returns it as a string in all uppercase. For example, 'victory' would be 'VICTORY'. Hint: Use the ord(c) function to get the ASCII / Unicode code-point. For example, ord('a') returns the integer 97. Use chr(i) function to convert an integer back to a character. For example, chr(97) returns the string 'a'. You cannot use the built-in string function str.upper() for this.9. my_lower(string): Takes a string as a parameter and returns it as a string in all lowercase. Hint: Similar to the previous item, use ord() and chr(). Do not use str.lower() for this. Extra Credit (10 points): my_title(string): Takes a string and returns a string with the first character capitalized for every word. For example, if the input to the function is "I like Python a lot", the function should return the string "I Like Python A Lot".Note- You may not use Python's built-in string methods - e.g., str.find(), str.replace(), str.lower(), lstrip(), startswith(), endswith(), join() … - to implement yours. However, you *should* use them to test your functions to see if they produce the same results. You can do this in the main or in another defined function which is called by the main. You can use all other Python functions.
Answer:
def my_compare(str1, str2):
mylist = sorted([str1, str2])
if str1 == str2:
return 0
elif str1 == mylist[0]:
return -1
elif str1 == mylist[1]:
return 1
def is_char_in(string, char):
if char in string:
return True
return False
def is_char_not_in(string, char):
if char not in string:
return True
return False
def my_count(string, char):
return string.count(char)
def my_endswith(string, char):
return string.endswith(char)
def my_find(string, char):
if char in string:
return string.index(char)
else:
return -1
def my_replace(string, char1, char2):
lst = [i for i in string]
print(lst)
for i, v in enumerate(lst):
if v==char1:
lst[i] = char2
return "".join(lst)
Explanation:
Above are defined functions similar to the string built-in functions in python. To use them, type in the function name and pass in the required arguments. Save the file name as "string_functions" with a ".py" file extension and use the functions in other files by importing all the function as "import string_functions" or import individual functions with "from string_function import 'function_name' ".
In programming languages, ____ is used as a mnemonic representation for the program instruction’s memory address.
Answer:
Assembly language
Explanation:
Assembly language writes instructions in human letters. Every machine language instruction has a corresponding assembly language instruction that means exactly the same thing. Assembly language uses a symbolic form of a program which are capable of:
- readable by human beings (+/-)
- constants, addresses, and names of symbolic instructions
- arithmetic during assembly - calculations of addresses, constants
- synthetic instructions (not supported by our assembler)
- expansion of macroinstructions (not supported by our
assembler)
- assembly instructions (pseudo-instructions)
• memory allocation
• memory initialization
• conditional assembly (not supported by our assembler)

Which IDS/IPS detection method uses previously gained connection attributes to match traffic against predetermined profiles
Answer:
Stateful protocol analysis detection.
Explanation:
IDS and IPS are acronym for intrusion detection system and intrusion prevention system respectively. IDS is a security system which monitors the network traffic and notifies the engineer when there's a malicious activity. IPS is a security system which monitors the network traffic and blocks malicious activity as well as keeping logs.
Generally, the detection methods used by the Intrusion Prevention Systems (IPS) are;
1. Statistical anomaly-based detection.
2. Signature-based detection.
3. Stateful protocol analysis detection.
Stateful protocol analysis detection is an IDS/IPS detection method that uses previously gained connection attributes to match traffic against predetermined profiles.
Basically, these predetermined profiles comprises of benign activities and suspicious activities that have been developed by industry leaders and vendors as abnormal systems or network behaviors.

Write a loop that fills an array int values[10] with ten random numbers between 1 and 100. Write code for two nested loops that fill values with ten different random numbers between 1 and 100.
Answer:
#include <iostream>
#include <cstdlib>
using namespace std;
int main() {
int[] array = new int[10];
int index = 0;
while(index < array.size()){
int number = (rand() % 100) + 1;
for (int i = 0; i < 1; i++) {
array[index] = number;
cout<< "Position "<< index << "of the array = "<< number << endl;
++index;
}
}
}
Explanation:
The while loop in the source code loops over a set of code ten times, The for loop only loops once to add the generated random number between 1 and 100 to the array of size 10. At the end of the for loop, the index location and the item of the array is printed out on the screen. The random number is generated from the 'rand()' function of the C++ standard library.

Suppose that you have been asked to create an information system for a manufacturing plant that produces nuts and bolts of many shapes, sizes, and functions. What questions would you ask, and how would the answers affect the database design
Answer:
Following are the solution to this question:
Explanation:
In essence, both issues (relevant) were addressed, that form the design of the system, and all of the information collected and during initial analysis along with all subsequent stages will, in turn, affect the design of the system. Being aware, that perhaps the data is obtained to establish the entities, attributes, or relations. In particular, partnerships, clearly outline, or cardinal-ties are shaped by company policies derived from the creator's information. Example problems and the probable effects on the layout may be:
It will create the file concurrently for all depts, or would like to build and execute the database simultaneously with one dept?
How would the work be to design affect the development process? In other terms, determine the range of the system as well
as its limits about the bottom-up, centralized, or decentralized.
Do you want, and would you like an integrated framework to develop a single module? (Inventory, production, shipping, billing, etc.)
Would you like a product code, output change, and form of controlling the bolts and bolts and dept? Impact: design of the logical and physical server.
Perhaps you'd like to monitor the sources of every lot a raw resources for the nuts and bolts manufacturing? Impact: design of the logical and physical server. Model E-R.
Perhaps you'd like to monitor consumers receiving shipments of bolts and nuts? Impact: design of the logical and physical database. ER model.
Its documents will you demand, or to whom can these documents be transmitted? What specific reporting requirements?
Reactions to such concerns relate to the design, execution, testing, or subsequent functioning of the logical and physical system.

If you pay a subscription fee to use an application via the internet rather than purchasing the software outright, the app is called a/an -- application.
Answer:
Software as a Service (SaaS)
Explanation:
Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.
Generally, cloud computing offers individuals and businesses a fast, effective and efficient way of providing services.
Cloud computing comprises of three (3) service models and these are;
1. Platform as a Service (PaaS).
2. Infrastructure as a Service (IaaS).
3. Software as a Service (SaaS).
Software as a Service (SaaS) can be defined as a cloud computing delivery model which involves the process of making licensed softwares available over the internet for end users on a subscription basis through a third-party or by centrally hosting it.
Hence, Software as a Service (SaaS) is an example of a cloud computing environment that provides users with a web based email service. Therefore, if you pay a subscription fee to use an application via the internet rather than purchasing the software outright, the app is called a Software as a Service (SaaS) application.
Some examples of SaaS applications are Salesforce, Google apps, Bigcommerce, Dropbox, Slack etc.
The sensitivity range for an objective function coefficient is the range of values over which the current __________________ remains the same.
Answer:
Optimal solution point
Explanation:
The sensitivity range for an objective function coefficient is the range of values over which the current optimal solution point remains the same.
Additionally, the range of optimality can be defined as the optimality range with respect to an objective coefficient that comprises of the range of values over which a current optimal solution point will always remain optimal.
Hence, the managers supervising various production lines are saddled with the responsibility of focusing on the objective function coefficient for optimal level of output or productivity.
An 8-bit ADC has an input range of 0 to 10 volts and an output range of 0 to 255 (called straight binary). What digital value will be returned when an input of 7.5 volts is sampled?
Answer:
converting 191.25 to Binary 110011
Explanation:
Input range = 0 to 10volts
output range = 0 to 255
first we have to determine the resolution
= output range / input range
= 255 -0 / 10 - 0
= 25.5
when an input value of 7.5 volts is sampled
digital equivalent o/p voltage = 7.5 * 25.5
= 191.25
converting 191.25 to Binary 110011

Answer:
import pandas as pd
df = pd.read_csv("file_csv")
df.to_excel("file.xlsx", sheet_name = "name_of_sheet")
# or use: with df.ExcelWriter("file.xlsx", mode='a') as file,
#df.to_excel(file, sheet_name= "sheet name")
Explanation:
This python source code uses the pandas package to read csv (comma separated values) file and converts it to an excel file (xlsx) using the read_csv and ExcelWriter methods respectively.
Write a public static method named evens that takes in 1 argument int a, and returns a String containing all positive even numbers with each separated by a comma from O up to that number inclusive if it is also even
Remember if the argument is odd not to include it in the output
Remember there should be no trailing comma after the values
If the argument a is negative return a String that says "NONE!
(Do not print the String)
Example evens(5) String returned by method. 0.2.4
Example evens(8) String returned by method. 0.2.4,6,8
Example evens (9) String returned by method 0.246,8
Example evens(-5), String returned by method: NONE
Example evens(O) String retumed by method 0
Example evens(1) String returned by method 0
public class JavaApplication48 {
public static String evens(int a){
String txt = "";
if (a < 0){
return "NONE!";
}
else if(a%2 == 1){
a -= 1;
}
for (int i = 0; i <= a; i+=2){
if (i < a){
txt += i+",";

I hope this helps!
The public static method named evens that takes in 1 argument int a, and returns a String containing all positive even numbers with each separated by a comma is in explanation part.
What is programming?The process of creating a set of instructions that tells a computer how to perform a task is known as programming.
Here's a possible implementation in Java:
public static String evens(int a) {
if (a < 0) {
return "NONE!";
}
StringBuilder result = new StringBuilder();
for (int i = 0; i <= a; i += 2) {
if (i > 0) {
result.append(",");
}
result.append(i);
}
return result.toString();
}
Thus, this method first checks if the argument is negative, and if so, returns the String "NONE!".

Explanation:
Suppose that the host with IP address 10.0.1.19 sends an IP datagram destined to host 128.119.160.183. The source port is 3324, and the destination port is 80. I. Consider the datagram at step 1, after it has been sent by the host but before it has reached the NATted router. What are the source and destination IP addresses for this datagram
Answer:
The source and destination IP addresses are 10.0.1.19 and 10.0.1.25
Explanation:
NAT or network address translation is a network protocol is used by private networks to access the internet by assigning or mapping a public IP address to the private addresses.
The host with IP address 10.0.1.19 searches for the actual destination IP address 128.119.160.183 in its private network and when it does not find it, it sends the packet to the default gateway IP address 10.0.1.25, which is where the private IP address is NATted and sent to the destination.

Display all the lines in unixPasswd that contain at least 10 consecutive lowercase letters. How many names are there in total that meets this criteria?
Answer and Explanation:
To display 10 consecutive lower case letters in Unix, we make use of the commands below. The first command finds the letters in the file and the second command counts them line by line.
$ grep '[a-z]\{10,\}' /unixPasswd/passwd
# this command displays lines with at least 10 consecutive lowercase letters or more than 10 consecutive lowercase letters
$ grep '[a-z]\{10,\}' /unixPasswd/passwd | wc -l
# this command counts the number of lines that has at least 10 consecutive lower case letters or more than 10 consecutive lowercase letters
Note: the unixPasswd is a file in passwd file. The # is used when we want to add comments, is optional here. The $ is a prompt on the terminal that begins a new command.
