Return to the Product Mix worksheet. Benicio wants to provide a visual way to compare the scenarios. Use the Scenario Manager as follows to create a PivotTable that compares the profit per unit in each scenario as follows:
a. Create a Scenario PivotTable report using the profit per unit sold (range B17:F17) as the result cells.
b. Remove the Filter field from the PivotTable.
c. Change the number format of the value fields to Currency with 2 decimal places and the $ symbol.
Answer:
To create a pivot table, select the columns to pivot and click on the insert option, click on the pivot table option and select the data columns for the pivot, verify the table range, select the location for the pivot and click ok. To format a column, select the columns and click the number option on the home tab, select the currency option and click on the number of decimal places
Explanation:
Microsoft Excel is a great tool for data analysis and visualization. It has several mathematical, engineering, statistical, and graphical tools for working with data.
A pivot-table is an essential tool for describing and comparing data of different types.
The steps to follow in order to produce a Pivot table would be as mentioned below:
Opting the columns for a pivot table. Now, make a click on the insert option. This click is followed by opting for the pivot table and the data columns that are available in it.After this, the verification of the range of the table is made and then, the location for the pivot table has opted. After this, the column is formatted and the number option is selected followed by the currency option, and the quantity of decimal places. A Pivot table allows one to establish a comparison between data of distinct categories(graphic, statistical, mathematical) and elaborate them.Learn more about 'Pivot Table' here:

c Assign to maxSum the max of (numA, numB) PLUS the max of (numY, numZ). Use just one statement. Hint: Call FindMax() twice in an expression.
Answer:
maxSum = FindMax(numA, numB) + FindMax(numY, numZ);
Explanation:
In the statement, maxSum is a double type variable which is assigned the maximum of the two variables numA numB PLUS the maximum of the two variables numY numZ using which are found by calling the FindMax function. The FindMax() method is called twice in this statement one time to find the maximum of numA and numB and one time to find the maximum of numY numZ. When the FindMax() method is called by passing numA and numB as parameters to this method, then method finds if the value of numA is greater than that of numB or vice versa. When the FindMax() method is called by passing numY and numZ as parameters to this method, then method finds if the value of numY is greater than that of numZ or vice versa. The PLUS + sign between the two method calls means that the resultant values returned by the FindMax() for both the calls are added and the result of addition is assigned to maxSum. The screenshot of program along with its output is attached.
Suppose one machine, A, executes a program with an average CPI of 1.9. Suppose another machine, B (with the same instruction set and an enhanced compiler), executes the same program with 20% less instructions and with a CPI of 1.1 at 800MHz. In order for the two machines to have the same performance, what does the clock rate of the first machine need to be
Answer:
the clock rate of the first machine need to be 1.7 GHz
Explanation:
Given:
CPI of A = 1.9
CPI of B = 1.1
machine, B executes the same program with 20% less instructions and with a CPI of 1.1 at 800MHz
To find:
In order for the two machines to have the same performance, what does the clock rate of the first machine need to be
Solution:
CPU execution time = Instruction Count * Cycles per Instruction/ clock rate
CPU execution time = (IC * CPI) / clock rate
(IC * CPI) (A) / clock rate(A) = (IC * CPI)B / clock rate(B)
(IC * 1.9) (A) / clock rate(A) = (IC * (1.1 * (1.0 - 0.20)))(B) / 800 * 10⁶ (B)
Notice that 0.20 is basically from 20% less instructions
(IC * 1.9) / clock rate = (IC * (1.1 * (1.0 - 0.20))) / 800 * 10⁶
(IC * 1.9) / clock rate = (IC*(1.1 * ( 0.8))/800 * 10⁶
(IC * 1.9) / clock rate = (IC * 0.88) / 800 * 10⁶
clock rate (A) = (IC * 1.9) / (IC * 0.88) / 800 * 10⁶
clock rate (A) = (IC * 1.9) (800 * 10⁶) / (IC * 0.88)
clock rate (A) = 1.9(800)(1000000) / 0.88
clock rate (A) = (1.9)(800000000) / 0.88
clock rate (A) = 1520000000 / 0.88
clock rate (A) = 1727272727.272727
clock rate (A) = 1.7 GHz

Which function is used to display a string value to the screen?
main[]
print()
run=
SHOW!
Answer:
The correct answer to this question is given below in the explanation section.
Explanation:
in most programming languages, the print() function is used to display a string value to the screen. Because, the print function prints all the string given in it as a parameter.
for example: to print hello world.
we use the function to print hello world as print("hello world").
However, it noted that other options are not correct because the main() function is an entry point of a program and it does not print string value to the screen. while run and show function do not print string value of screen also.

Create a class named Invoicing that includes three overloaded computeInvoice() methods for a book store: see pages 196 for examples… The 8% tax should be defined as a constant.
1. When computeInvoice() receives a single parameter, it represents the price of one book ordered. Add 8% tax and display the total due.
2. When computeInvoice() receives two parameters, they represent the price of a book and the quantity ordered. Multiply the two values, add 8% tax, and display the total due.
3. When computeInvoice() receives three parameters, they represent the price of a book, the quantity ordered, and a coupon value. Multiply the quantity and price, reduce the result by the coupon value, and then add 8% tax and display the total due.
Create a driver class named TestInvoice with a main() method that tests all three overloaded methods using the following data: Price $24.95 Price, $17.50, quantity 4, Price $10.00, quantity 6, coupon $20.00 Output printed to Eclipse Console:

A Windows user is locked out of her computer, and you must log into the local administrator account HelpdeskAdmin. Which would you use in the username field?
Answer: .\HelpdeskAdmin
Explanation:
If you wanted to log in as the local administrator then for the Username put a dot (.) and a backslash (\) in front of the Admin username.
The dot(.) will ensure that Windows knows that you are logging into a local computer as the administrator and so will grant you access. The relevant username therefore is, ''.\HelpdeskAdmin''.
I will use .\HelpdeskAdmin as the username field.
What is a username field?The username-field is known to be a kind of command that is said to specifies the value for the name that shows the characteristics in the login form and it is one that identifies the username field.
Note that the use of the .\HelpdeskAdmin as the username field is the right thing to do as the dot(.) will make sure that the Windows knows that the user is logging into a computer as the administrator.

The one that is not a period of the Middle Ages is the High Middle Ages. The correct option is c.
What are different ages?The Middle Ages, which roughly correspond to the years 500 to 1400–1500 BCE, is the term used to describe this time of European history. The phrase was initially used by academics in the 15th century to refer to the time frame between their own era and the dissolution of the Western Roman Empire.
The period between the fall of Imperial Rome and the start of Early Modern Europe is referred to as the “Middle Ages” for this reason. The reason the Middle Ages are known as the Dark Ages is that life was hard and brief in Europe, and contrasted with the orderliness of classical antiquity.
The time period in European history from roughly 500 AD to 1500 AD. This time period's early years are commonly referred to as the Dark Ages.

for x in string:
if not d.get(x):
d[x] = 1
else:
d[x] += 1
return d
Part 2:
Create a function named build_word_counter that has the same signature as build_dictionary. This function also returns a dictionary, however, it normalizes each word such that the case of the word is ignored (i.e. case insensitive). So the words LIKE, Like, like should be considered the same word (much like a regular dictionary would). You must use the same function add_item again (so don't make any modifications to it) Normalize words by using the lower case version of the word.
Part 3:
Create a function named build_letter_distribution that has the same signature as build_dictionary. This function returns a dictionary; however, each key will be a letter and the value will be the count that represents how many times that letter was found. Essentially you will have a letter distribution over a sentence (which is a list of words). The letters should be case insensitive.
Answer:
Follows are the code to this question:
def build_word_counter(string):#defining a method build_word_counter that accepts string as a parameter
d = dict()#defining d variable as a dictionary
for x in string:#defining for loop that use string

In the first program a method, "build_word_counter" is defined that accepts a string variable in its parameter, and inside the method, a dictionary variable "d" is defined that uses the for loop to hold string value and convert all value into lower case.
In the next step, a conditional statement is used that holds value in the dictionary and count its word value.
In the second program a method, "build_letter_distribution" is defined that holds string variable in its parameter, and inside the method, a dictionary variable "d" is defined that uses the two for loop and in if the block, it holds value in the dictionary and returns its value, and use print method to print its return its value.

In a system where Round Robin is used for CPU scheduling, the following is TRUE when a process cannot finish its computation during its current time quantum? The process will terminate itself. The process will be terminated by the operating system. The process's state will be changed from running to blocked. None of the mentioned.
Answer:
B. The process will be terminated by the operating system.
Explanation:
When Round Robin is used for CPU scheduling, a time scheduler which is a component of the operating system is used in regulating the operation. A time limit is set for each of the processes to be run.
So, when a process fails to complete running before its time elapses, the time scheduler would log it off and return it to the queue. This queue is in a circular form and gives each of the processes a chance to run its course.
Based on the information given regarding CPU scheduling, the correct option is C. The process's state will be changed from running to blocked.
It should be noted that in a system where Round Robin is used for CPU scheduling, when a process cannot finish its computation during its current time quantum, the process's state will be changed from running to blocked.
It should be noted that a prices transition to a blocked state occurs when it's waiting for some events like a particular resource becoming available.

Consider a multiprocessor CPU scheduling policy. There are 2 options: 1) a singlecommon ready queue of jobs; when a CPU becomes free, the job atthe head of the queuegoes to this free CPU. 2) a ready queue for each CPU; the arriving job joins the shortestqueue. In general, do you expect the common queue or the shortest queue policy to performbetter. Justify.
Explanation:
A ready queue is more adequate since in this method the load balancing occurs in a proper way. The goal of multiple processing is the correct distribution of load.
But in the cases when a processor is doing quicker or taking a smaller queue, it will self assign processes allotted for execution, configuring it with a constant busy state.
802.11ac provides an advantage over 802.11n by incorporating increased channel bonding capabilities. What size bonded channels does 802.11ac support?
Answer:
The 802.11ac wireless standard takes channel bonding to a higher level because it can support 20MHz, 40MHz, and 80MHz channels, with an optional use of 160MHz channels.
Explanation:
The 802.11ac is a standardized wireless protocol established and accepted by the institute of electrical and electronics engineers (IEEE). 802.11ac as a wireless local area network (WLAN) protocol, has multiple amplitude and bandwidth, thus making it to be the first standard wireless protocol to have the ability to operate on a Gigabit (Gb) network.
Generally, the 802.11ac wireless standard provides an advantage over 802.11n by incorporating increased channel bonding capabilities. The 802.11ac wireless standard takes channel bonding to a higher level because it can support 20MHz, 40MHz, and 80MHz channels, with an optional use of 160MHz channels.
