Explanation:
Think yourself and Differentiate the important tasks with the unimportant ones. You will get your answer today.
Many companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion: A, B, and C = 2 D, E, and F = 3 G, H, and I = 4 J, K, and L = 5 M, N, and O = 6 P, Q, R, and S = 7 T, U, and V = 8 W, X, Y, and Z = 9 Write a program that asks the user to enter a 12-character telephone number in the format: XXX-XXX-XXXX. Acceptable characters (X's) are A-Z and a-z. Your program should check for: The length of the phone number is correct. The dashes are included and are in the correct positions. There are no characters in the illegal characters in the string. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. If the input string is not entirely correct then you should print an error message. For example, if the user enters 555-GET-FOOD the program should display 555-438-3663. If the user enters 123-456-7890, the program should display 123-456-7890. Rules: You must have one function (in addition to main()) that converts an alphabetic character to a digit. Or you can have one function that coverts all characters to digits. You can make your own function or use a built-in function if one exists.
Answer:
The program in Python is as follows:
def convertt(phone):
splitnum = phone.split ('-')
valid = True
count = 0
err = ""
numphone = ""
if len(phone) != 12:
err = "Invalid Length"
valid = False
elif phone[3] != '-' or phone[7] != '-':
err = "Invalid dash [-] location"
valid = False
while valid== True and count < 3:
for ch in splitnum[count]:
if ch.isdigit():
numphone += ch
elif ch.upper()in 'ABC':
numphone += '2'
elif ch.upper()in 'DEF':
numphone += '3'
elif ch.upper()in 'GHI':
numphone += '4'
elif ch.upper() in 'JKL':
numphone += '5'
elif ch.upper()in 'MNO':
numphone += '6'
elif ch.upper()in 'PQRS':
numphone += '7'
elif ch.upper()in 'TUV':
numphone += '8'
elif ch.upper()in 'WXYZ':
numphone += '9'
else:
valid = False
err = "Illegal character in phone number"
if count!=2:
numphone += '-'
count += 1
if valid == False:
print (err)
else:
print ("Phone Number", numphone)
phone = input("Phone number: ")
convertt(phone)

The Syntax NPV formula includes the Rate, The Cash Flows, the number of payments, and the Future
Value.
Select one:
True
False
Answer:
False
Explanation:
NPV stands for Net Present Value, it is an important term in finance as it used to determine the value of money or investment based on a series of cashflows and specified discount rate. Excel provides a functions which aids easy calculation of the Net Present value of money or investment using the NPV formula. The syntax forbthe NPV formula is :
=NPV(rate,value 1, [value 2],...)
This formular requires only tow key parameters ; the discount rate, which comes first and the cashflows, which is designated in the syntax as values ; the cashflows is usually placed in a range of cells in excel and the cell range is inputed in the formular. Hence, the number of payments and future value aren't part of the NPV syntax.
Compile and Execute a Program
1. Compile Pay.java using the JDK or a Java IDE as directed by your instructor.
2. You should not receive any error messages.
3. When this program is executed, it will ask the user for input. You should calculate several different cases by hand. Since there is a critical point at which the calculation changes, you should test three different cases: the critical point, a number above the critical point, and a number below the critical point. You want to calculate by hand so that you can check the logic of the program. Fill in the chart below with your test cases and the result you get when calculating by hand.
4. Execute the program using your first set of data.
Record your result. You will need to execute the program three times to test all your data. Note: you do not need to compile again. Once the program compiles correctly once, it can be executed many times. You only need to compile again if you make changes to the code.

Why do entries in a local address resolution protocol table expire after a short amount of time?
Answer:
To account for network changes
Explanation:
Answer:
To account for network changes
Explanation:
Address Resolution Protocol (ARP) can be regarded as procedure that is been engaged in mapping of dynamic Internet Protocol address i.e (IP address) into permanent physical machine address( MAC Address) in a particular local area network (LAN).
ARP is utilized when there is need for
dynamically mapping of layer-3 network addresses into data-link addresses. It should be noted that the reason why entries in a local address resolution protocol table expire after a short amount of time is that it will be easy to account for network changes
How is an interpreter different from a compiler?
An interpreter translates and executes code line by line, while a compiler translates all code at once so that it is ready to be executed at any time.
An interpreter translates all code at once so that it is ready to be executed at any time, while a compiler translates and executes code line by line.
An interpreter translates programming code into binary language, while a compiler does not.
An interpreter translates binary language into programming language, while a compiler translates programming language into binary language.
Answer:
An interpreter is quite different from a complier due to the following statement below:
O. An interpreter translates and executes code line by line, while a compiler translates all code at once so that it is ready to be executed at any time.
Explanation:
For an interpreter, it works in translating and execution of the codes line after another line. In a situation where there is a mistake in the code, the next line would not be able to be executed, but rather display error message. On the other hand, compiler translate all codes at once and execute them as a single work.
During its translation of the codes in compiler, should there be any error, it would not be able to execute despite the fact that, the error might be in the last line of the code.

As of Spring 2020, in otder to get into the CS major, you must have a 3.0 GPA or better in cs120, cs210, and cs245. In this problem, you should write one function named get_gpa, which will calculate this GPA. This function should have one parameter, which will be a dictionary of grades in computer science courses. You can assume that the dictionary will always have the keys 'cs120', 'cs210', and 'cs245', but it also might contain some names of other courses too. The values associated with each key will be a float representeing the GPA-style grade for that class. For instance, the parameter dictionary might look like: {'cs120':4.0 'cs245':3.0, 'cs210':2.0}. Some examples:
get_gpa({'cs110': 4.0, 'cs245':3.0, 'cs335':4.0, 'cs120':3.0, 'cs210':3.0}) should return 3.0.
get_gpa({'cs110': 4.0, 'cs120':3.0, 'cs245':2.0, 'cs210':1.0}) should return 2.0.
get_gpa({'cs245':4.0, 'cs120':3.0, 'cs245':2.0}) should return 3.0.
Make sure to include only the one function in your file.
Answer:
The function is as follows:
def get_gpa(mydict):
gpa = 0
kount = 0
for course_code, gp in mydict.items():
if course_code == 'cs120' or course_code == 'cs210' or course_code == 'cs245':
gpa += float(gp)
kount+=1
return (gpa/kount)
Explanation:
This defines the function
def get_gpa(mydict):
This initializes gpa to 0
gpa = 0
This initializes kount to 0
kount = 0
This iterates through the courses
for course_code, gp in mydict.items():
If course code is cs120 or cs210 or cs245
if course_code == 'cs120' or course_code == 'cs210' or course_code == 'cs245':
The gpa is added
gpa += float(gp)
And the number of courses is increased by 1
kount+=1
This returns the gpa
return (gpa/kount)
When adding delegates to his mailbox, which role should Joel use if he would like the user to be able to read and create items in a particular folder?
- editor
- publishing editor
- author
- manager
Answer:
publishing editor
Explanation:
In this scenario, the role that he should choose for the delegates would be publishing editor. This role will allow them to create, read, modify, and delete all items within a given folder, and create subfolders. The other options listed either do not give access to create/modify existing files or simply only give all these rights with files that the user creates but not files that already existed in the folder. Therefore, this would be the best role for what Joel wants to accomplish.

In this problem, you should write one function named count_calories. This function should have one parameter, which will be a dictionary of food items. The keys will ne the name of a food item (such as 'granola' or 'steak'), and the value associated with each food will be the integer calorie amount for that food. The function should iterate through all of the foods and sum up the total calories, and then return that number. For example:
count_calories({'chocolate':200, 'milk':120, 'steak':250}) should return 570.
count_calories({'carrot':5, 'apple':50}) should return 55.
Make sure to include only the one function in your file.
Answer:
The function is as follows:
def count_calories(dictt):

Consider the following incomplete method. Method findNext is intended to return the index of the first occurrence of the value val beyond the position start in array arr. I returns index of first occurrence of val in arr /! after position start; // returns arr.length if val is not found public int findNext (int[] arr, int val, int start) int pos = start + 1; while condition '/ ) pos++ return pos; For example, consider the following code segment. int [ ] arr {11, 22, 100, 33, 100, 11, 44, 100); System.out.println(findNext (arr, 100, 2)) The execution of the code segment should result in the value 4 being printed Which of the following expressions could be used to replace /* condition */ so that findNext will work as intended?
(A) (posarr.length) &&(arr [pos]- val)
(B) (arr [pos] != val) && (pos < arr. Îength)
(C) (pos
(D) (arr [pos} == val) && (pos < arr. length)
(E) (pos
Answer:
B)
Explanation:
The while loop runs as long as two conditions are satisfied, as indicated by the && logical operator.
The first condition- arr[pos] != val
checks to see if the value in the array index, pos, is equal to the given value and while it is not equal to it, the second condition is checked.
The second condition(pos < are.length), checks to see if the index(pos) is less than the length of the array. If both conditions are true, the program execution enters the while loop.
The while loop is only terminated once arr[pos] == Val or pos == arr.length.

Manny has drafted an email message and configured a delivery option “Do not delivery before 5:00 PM and today’s date” he shuts down his computer and leaves for the day at 4:30 pm. What will happen at 5 pm?
- the message will be delivered from the server
- the message will be delivered from Manny’s computer
- the message will remain in manny’s outbox until the computer is started and the outlook programs is started the next day
- the message will remain in Manny’s outbox until the computer is started and he will be promoted
Answer:
Explanation:
In this scenario, the message will remain in manny’s outbox until the computer is started and the outlook programs is started the next day. When you create a message but do not send it, even if you schedule to send it, the message gets saved as a draft in your outbox. Once the scheduled time arrives the program will grab the message, prepare it, and send it. This will however not happen if the program is closed. Therefore, Manny's message will only send once the computer is turned on and the Outlook program relaunches.

HLOOKUP is used for Horizontal Data look ups while VLOOKUP is for Vertical Data look ups
Select one:
True
False
Answer:
True
Explanation:
Both HLOOKUP and VLOOKUP are excel functions used for searching through tables for a specified lookup value to either get an exact or approximate match. The VLOOK and HLOOKUP functions have identical syntax which only differs with the HLOOKUP requiring the row index number to search through the rows while, VLOOKUP requires the column index number to search through the columns. Other than this difference, the other syntax values are the same.
VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])
HLOOKUP(lookup_value, table_array, row_index_num, [range_lookup])
