Answer:
Explanation:
/* From the information provided, For now will consider the name of table as TRIPGUIDES*/
/*In all the answers below, the syntax is based on Oracle SQL. In case of usage of other database queries, answer may vary to some extent*/
1.
Select R.Reservation_ID, R.Trip_ID , C.Customer_Num,C.Last_Name from Reservation R, Customer C where C.Customer_Num=R.Customer_Num ORDER BY C.Last_Name
/*idea is to select the join the two tables by comparing customer_id field in two tables as it is the only field which is common and then print the desired result later ordering by last name to get the results in sorted order*/
2.
Select R.Reservation_ID, R.Trip_ID , R.NUM_PERSONS from Reservation R, Customer C where C.Customer_Num=R.Customer_Num and C.LAST_NAME='Goff' and C.FIRST_NAME='Ryan'
/*Here, the explaination will be similar to the first query. Choose the desired columns from the tables, and join the two tables by equating the common field
*/
3.
Select T.TRIP_NAME from TRIP T,GUIDE G,TRIPGUIDES TG where T.TRIP_ID=TG.TRIP_ID and TG.GUIDE_NUM=G.GUIDE_NUM and G.LAST_NAME='Abrams' and G.FIRST_NAME='Miles'
/*
Here,we choose three tables TRIP,GUIDE and TRIPGUIDES. Here we selected those trips where we have guides as Miles Abrms in the GUIDES table and equated Trip_id from TRIPGUIDES to TRIP.TRIP_Name so that can have the desired results
*/
4.
Select T.TRIP_NAME
from TRIP T,TRIPGUIDES TG ,G.GUIDE
where T.TRIP_ID=TG.TRIP_ID and T.TYPE='Biking' and TG.GUIDE_NUM=G.GUIDE_NUM and G.LAST_NAME='Boyers' and G.FIRST_NAME='Rita'
/*
In the above question, we first selected the trip name from trip table. To put the condition we first make sure that all the three tables are connected properly. In order to do so, we have equated Guide_nums in guide and tripguides. and also equated trip_id in tripguides and trip. Then we equated names from guide tables and type from trip table for the desired results.
*/
5.
SELECT C.LAST_NAME , T.TRIP_NAME , T.START_LOCATION FROM CUSTOMER C, TRIP T, RESERVATION R WHERE R.TRIP_DATE='2016-07-23' AND T.TRIP_ID=R.TRIP_ID AND C.CUSTOMER_NUM=R.CUSTOMER_NUM
/*
The explaination for this one will be equivalent to the previous question where we just equated the desired columns where we equiated the desired columns in respective fields and also equated the common entities like trip ids and customer ids so that can join tables properly
*/
/*The comparison of dates in SQL depends on the format in which they are stored. In the upper case if the
dates are stored in the format as YYYY-MM-DD, then the above query mentioned will work. In case dates are stored in the form of a string then the following query will work.
SELECT C.LAST_NAME , T.TRIP_NAME , T.START_LOCATION FROM CUSTOMER C, TRIP T, RESERVATION R WHERE R.TRIP_DATE='7/23/2016' AND T.TRIP_ID=R.TRIP_ID AND C.CUSTOMER_NUM=R.CUSTOMER_NUM
*/
6.
Select R.RESERVATION_ID, R.TRIP_ID,R.TRIP_DATE FROM RESERVATION R WHERE R.TRIP_ID IN
{SELECT TRIP_ID FROM TRIP T WHERE STATE='ME'}
/*
In the above question, we firstly extracted all the trip id's which are having locations as maine. Now we have the list of all the trip_id's that have location maine. Now we just need to extract the reservation ids for the same which can be trivally done by simply using the in clause stating print all the tuples whose id's are there in the list of inner query. Remember, IN always checks in the set of values.
*/
7.
Select R.RESERVATION_ID, R.TRIP_ID,R.TRIP_DATE FROM RESERVATION WHERE
EXISTS {SELECT TRIP_ID FROM TRIP T WHERE STATE='ME' and R.TRIP_ID=T.TRIP_ID}
/*
Unlike IN, Exist returns either true or false based on existance of any tuple in the condition provided. In the question above, firstly we checked for the possibilities if there is a trip in state ME and TRIP_IDs are common. Then we selected reservation ID, trip ID and Trip dates for all queries that returns true for inner query
*/
8.
SELECT G.LAST_NAME,G.FIRST_NAME FROM GUIDE WHERE G.GUIDE_NUM IN
{
SELECT DISTINCT TG.GUIDE_NUM FROM TRIPGUIDES TG WHERE TG.TRIPID IN {
SELECT T.TRIP_ID FROM TRIP T WHERE T.TYPE='Paddling'
}
}
/*
We have used here double nested IN queries. Firstly we selected all the trips which had paddling type (from the inner most queries). Using the same, we get the list of guides,(basically got the list of guide_numbers) of all the guides eds which were on trips with trip id we got from the inner most queries. Now that we have all the guide_Nums that were on trip with type paddling, we can simply use the query select last name and first name of all the guides which are having guide nums in the list returned by middle query.

Consider the following class in Java:
public class MountainBike extends Bicycle {
public int seatHeight;
public MountainBike(int startHeight,
int startCadence,
int startSpeed,
int startGear) {
super(startCadence, startSpeed, startGear);
seatHeight = startHeight;
}
public void setHeight(int newValue) {
seatHeight = newValue;
}
}
What is this trying to accomplish?
super(startCadence, startSpeed, startGear);
a. Four fields of the MountainBike class are defined: super, startCadence, startSpeed and startGear.
b. The constructor for the parent class is called.
c. A method of the MountainBike class named super is defined.
d. Three fields are defined for the MountainBike class as intances of the class named super.
Answer:
b. The constructor for the parent class is called.
Explanation:
In this case this specific piece of code is calling the constructor for the parent class. Since a MountainBike object is being created. This creation uses the MountainBike class constructor but since this is a subclass of the Bicycle class, the super() method is calling the parent class constructor and passing the variables startCadence, startSpeed, startGear to that constructor. The Bicycle constructor is the one being called by super() and it will handle what to do with the variables inputs being passed.
RecursionexerciseCOP 3502; Summer2021We have gone through many examples in the class and those examples are available in the slides and uploaded codes. Try to test those codes and modify as you wish for getting more clarification.In additiontry the following:---------------------------------------------------------------------------------------------------------------------------------------1.What would be the output of the following recursive function if we call rec2(5)
Answer:
The output is:
1 2 3 4 5
Explanation:
Given
See attachment for code segment
Required
The output of rec2(5)
From the attached code segment, we have the following:
The base case: if (x==0){ return;}
The above implies that, the recursion ends when the value of x gets reduced to 0
The recursion:
rec2(x-1); ---- This continually reduces x by 1 and passes the value to the function
printf("%d ", x); This prints the passed value of x
Hence, the output of rec2(5) is: 1 2 3 4 5
Write a program that removes all non-alpha characters from the given input. Ex: If the input is: -Hello, 1 world$! the output is: Helloworld

Compute change
A cashier distributes change using the maximum number of five dollar bills, followed by one dollar bills. For example, 19 yields 3 fives and 4 ones. Write a single statement that assigns the number of one dollar bills to variable numOnes, given amountToChange. Hint: Use the % operator.
import java.util.Scanner;
public class ComputingChange {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
int amountToChange;
int numFives;
int numOnes;
amountToChange = scnr.nextInt();
numFives = amountToChange / 5;
/* Your solution goes here */
System.out.print("numFives: ");
System.out.println(numFives);
System.out.print("numOnes: ");
System.out.println(numOnes);
}
}
Answer:
Explanation:
The following code is written in Java and modified to do as requested. It asks the user to enter a number that is saved to the amountToChange and then uses the % operator to calculate the number of 5 dollar bills and the number of 1 dollar bills to give back. A test case has been provided and the output can be seen in the attached image below.
import java.util.Scanner;
class ComputingChange {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
int amountToChange;
int numFives;
int numOnes;
amountToChange = scnr.nextInt();
numFives = amountToChange / 5;
/* Your solution goes here */
numOnes = amountToChange % 5;
System.out.print("numFives: ");
System.out.println(numFives);
System.out.print("numOnes: ");
System.out.println(numOnes);
}

The valid call to the function installApplication is
void main( )
{
// call the function installApplication
}
void installApplication(char appInitial, int appVersion)
{
// rest of function not important
}
Answer:
B. installApplication(‘A’, 1);
Explanation:
Given
The above code segment
Required
The correct call to installApplication
The function installApplication is declared as void, meaning that it is not expected to return anything.
Also, it receives a character and an integer argument.
So, the call to this function must include a character and an integer argument, in that order.
Option D is incorrect because both arguments are integer
Option C is incorrect because it passes no argument to the function.
Option A is incorrect because it receives an integer value from the function (and the function is not meant not to have a return value).
Option B is correct

Explanation:
How many ways are there to arrange the letters in the word ALGORITHMS? Note, the letter arrangement does not have to spell a word in the dictionary, but the new word must contain all the letters and each letter can be used only once.
there are ten letters in the word, so for the first position we can choose out of 10 option.
no matter wich specific option we choose, we will have 9 letters left for the 2nd letter.
and 8 for the third place.
...
when we will have used up 9 of 10 letters, there will be only one option for the last place.
the number of possible decision-paths is therefore given by this expression:
10*9*8*7*6*5*4*3*2*1
wich is 3,628,800
there are quite a few ways to rearrange 10 letters
The sorting method which commands entries in a going to head predicated on each character without regard to space as well as punctuation, therefore there are 3628800 ways.
The word 'ALGORITHMS' has 10 letters. There is no repeated letter so, the first Letter can hold 10 places if we start taking one letter at a time. The second can then hold nine positions, the third can hold eight, and so on.So, as [tex]\bold{ 10\times 9 \times 8.... \times 3 \times 2 \times 1 = 362,8800}[/tex] ways, we have such a total number of ways.

It will be great if you could explain the answer to me. :)
Answer:
see your answer in image
mark me brainlist
The amount of disk space in sectors that would be required to store 300,000 records is equal to 75,000 sectors.
Given the following data:
Number of records = 300,000.Size of each logical record = 120 byte.Number of bytes (sector) = 512.Number of sectors per track = 96.Number of tracks per surface = 110.How to calculate the required disk space?First of all, we would determine the number of logical records that can be held by each sector as follows:
Number of logical records per sector = 512/120
Number of logical records per sector = 4.3 ≈ 4.0.
Now, we can calculate the required disk space to store 300,000 records:
Disk space = 300,000/4
Disk space = 75,000 sectors.
For the tracks, we have:
Disk space in tracks = 75,000/96
Disk space in tracks = 781.25 ≈ 782.
Disk space in tracks = 782 tracks.
For the surfaces, we have:
Disk space in surfaces = 782/110
Disk space in surfaces = 7.10 ≈ 8.
Disk space in surfaces = 8 surfaces.

Many companies possess valuable information they want to guard closely (ex. new chip design, competition plans, legal documents). Personal computer hard disks these days are full of important photos, videos, and movies. As more and more information is stored in computer systems, the need to protect it is becoming increasingly important. Which of the following statements is incorrect with respect to Security?
a. security has many facets; three of the more important ones are: the nature of the threats, the nature of intruders, and cryptography
b. data integrity means that unauthorized users should not be able to modify any data without the owner's permission
c. a common category of intruders are driven by determined attempts to make money; for example: bank programmers attempting to steal from the bank they work for
d. in addition to threats caused by malicious users, data can be lost by accident; for example: rats gnawing backup tapes
Answer: D. in addition to threats caused by malicious users, data can be lost by accident; for example: rats gnawing backup tapes
Explanation:
Data security is essential to protecting unwanted people from having access to ones data, malicious attack should also be prevented and unusual behavior should be monitored.
Data security has many facets such as threat nature, the nature of intruders, and cryptography. Furthermore, data integrity means that unauthorized users should not be able to modify any data without the owner's permission. Also, the statement that a common category of intruders are driven by determined attempts to make money; for example: bank programmers attempting to steal from the bank they work for is correct.
It should be no noted that rats gnawing backup tapes cannot prevent data loss. Therefore, the correct option is D

that the student accesses an electronic course catalog to find out about available courses. Which design
model should be followed by this secenario? Draw any two UML diagrams.
Answer:
Follows are the complete question to the given question:
Explanation:
The UML scheme is a UML-based diagram intended to depict the system visually, together with its key actors, roles, activities, objects, and classes, to gather information the about system, change that, or maintain it.
Every complex process is better understood via sketches or pictures. These diagrams have a higher understanding effect. By glancing about, we notice that diagrams are not a new idea but are widely used in various business types. To enhance understanding of the system, we prepare UML diagrams. There is not enough of a single diagram to represent all aspects of the system. You can also create customized diagrams to satisfy your needs. Iterative and incremental diagrams are usually done.
There are two broad diagram categories and that they are broken into subclasses again:

Total Number of bits [tex]= 125829120 \ bits[/tex]
Now
The transmission rate of the total link= 49.7 Gbps
[tex]1\ Gbps = 1000000000\ bps\\\\49.7 \ Gbps = 49.7 \times 1000000000 =49700000000\ bps\\\\FDM \ \ network[/tex]
[tex]\text{Calculating the transmission rate for 1 time slot:}[/tex]
[tex]=\frac{ 49700000000}{7} \ bits / second\\\\= 7100000000 \ bits / second\\\\ = \frac{49700000000}{(10^{3\times 7})} \ in\ milliseconds\\\\ =7100000 \ bits / millisecond[/tex]
Now,
[tex]\text{Total time taken to transmit 15 MiB of file} = \frac{\text{Total number of bits}}{\text{Transmission rate}}[/tex]
[tex]= \frac{125829120}{7100000}\\\\= 17.72\\\\[/tex]
[tex]\text{Total time = Setup time + Transmission Time}\\\\[/tex]
[tex]= 84.5+ 17.72\\\\= 102.2 \ milliseconds[/tex]

Here's some fake data.
df = {'country': ['US', 'US', 'US', 'US', 'UK', 'UK', 'UK'],
'year': [2008, 2009, 2010, 2011, 2008, 2009, 2010],
'Happiness': [4.64, 4.42, 3.25, 3.08, 3.66, 4.08, 4.09],
'Positive': [0.85, 0.7, 0.54, 0.07, 0.1, 0.92, 0.94],
'Negative': [0.49, 0.09, 0.12, 0.32, 0.43, 0.21, 0.31],
'LogGDP': [8.66, 8.23, 7.29, 8.3, 8.27, 6.38, 6.09],
'Support': [0.24, 0.92, 0.54, 0.55, 0.6, 0.38, 0.63],
'Life': [51.95, 55.54, 52.48, 53.71, 50.18, 49.12, 55.84],
'Freedom': [0.65, 0.44, 0.06, 0.5, 0.52, 0.79, 0.63, ],
'Generosity': [0.07, 0.01, 0.06, 0.28, 0.36, 0.33, 0.26],
'Corruption': [0.97, 0.23, 0.66, 0.12, 0.06, 0.87, 0.53]}
I have a list of happiness and six explanatory vars.
exp_vars = ['Happiness', 'LogGDP', 'Support', 'Life', 'Freedom', 'Generosity', 'Corruption']
1. Define a variable called explanatory_vars that contains the list of the 6 key explanatory variables
2. Define a variable called plot_vars that contains Happiness and each of the explanatory variables. (Hint: recall that you can concatenate Python lists using the addition (+) operator.)
3. Using sns.pairplot, make a pairwise scatterplot for the WHR data frame over the variables of interest, namely the plot_vars. To add additional information, set the hue option to reflect the year of each data point, so that trends over time might become apparent. It will also be useful to include the options dropna=True and palette='Blues'.

The fastest way to pull financial data from the application into Excel as refreshable formulas that can be edited or updated is:
Answer:
Download the financial report as =FDS codes with cell referencing.
Explanation:
An excel is a spreadsheet that is developed by the Microsoft company for the Windows operating system. It can be also used in iOS, macOS and Android. It has many features including graphing tools, calculation, pivot tables, etc.
In excel the fastest way to pull out a financial data from an application into the Excel as the refreshable formulas which can be edited or can be uploaded later on is by downloading the financial report as an +FDS code with the cell referencing.
In excel, cell refreshing is a way to refer to a cell in the formula.
Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.

var num2 = 32;
var num1 = 12;
var rem=num2 % numi;
while(rem > 0)
{
num2 = num1;
num1 = rem;
rem = num2 % num1;
}
document.write(num1);
The output of the document.write statement at the end of this block is
Answer:
4
Explanation:
Given
The attached code segment
Required
The output
The first and second lines initialize num2 to 32 and num1 to 12, respectively.
Next, the remainder is calculated on line 3
[tex]rem = 32\%12[/tex]
[tex]rem = 8[/tex]
Then the while loop is repeated as long as rem > 0.
At first, we have:
[tex]num2 = 32[/tex]
[tex]num1 = 12[/tex]
[tex]rem = 8[/tex]
The first iteration gives:
[tex]num2 = 12[/tex]
[tex]num1 = 8[/tex]
[tex]rem = 12\%8 = 4[/tex]
Is 4 > 0? Yes; The loop is executed again.
This gives:
[tex]num2 = 8[/tex]
[tex]num1 = 4[/tex]
[tex]rem = 8\%4=0[/tex]
Is 0 > 0? No; The loop is executed
The last statement prints the last value of num1;
In the last loop, we have:
[tex]num1 = 4[/tex]
Hence, the output is 4
