Hi, you haven't provided the programing language in which you need the code, I'll just explain how to do it using Matlab, and you can apply a similar method for any programming language.
Answer:
attendanceValues = [attendanceValues(2:end),attendanceValues(end)]
Explanation step by step:
We take all the values of the array from the second position until the end, in this case, we use attendanceValues(2:end) for that. We take the last value of the array using attendanceValues(end). We create a single array based on the result of step one plus step two. We save the new array in the old one reusing attendanceValues.
The program written shifts the row array of attendance values one position to the left, the program written in python 3 goes thus :
attendanceValues = [10, 20, 30, 40]
#the variable attendanceValues is a list of integers
shiftedValues = attendanceValues[1:], attendanceValues[-1]
#using list slicing, the value is selected from index 1 till the end and the last index value is added.
print(shiftedValues)
#displays the values in the shiftedValues list.

Write a Python program that requests the price and weight of an item in pounds and ounces, and then determines the price per ounce from the below inputEnter price of item: 25.50Enter weight of item inpounds and ounces separately.Enter pounds: 1Enter ounces: 9Price per ounce: $1.02
Answer:
The program to this question as follows:
Program:
price=float(input('Enter total price: ')) #define variable price and take user-input
print('Enter value of weight separately into pounds and onces: ') #print message
pounds=int(input('Input pounds value: ')) # defining variable pounds and take user-input
ounces=int(input('Input ounces value: ')) # defining variable ounces and take user-input
total_ounces=pounds*16+ounces # defining variable total_ounces and calculate variable
total=price/total_ounces # defining variable total and calculate price/ounces
print('price/ounces is: ',total) #print value
Output:
Enter total price: 25.50
Enter value of weight separately into pounds and onces:
Input pounds value: 1
Input ounces value: 9
price/ounces is: 1.02
Explanation:
In the above python program code, a variable "price" is defined, that is takes price value from user, to take this value the "input and float" is used, in which the "float" convert value into decimal and input function is used for user- input.
In the next line, the print function is declared, which is used for print message and variable values, in this function, we print a message that takes two values separately. Then two-variable "pounds and ounces" are defined that take integer value separately.In the last step, the total_ounces variable is defined, which calculates total ounces and the total variable will use to calculate the price per ounces. The print function is used to print this variable value.
Write a function called show_info that takes a name, a home city, and a home state (a total of 3 arguments) and returns a full sentence string with the following content and format: Your name is [name] and you live in [city], [state].
Answer:
Below are the function for the above question in java Language---
void show_info(String name,String home,String state)
{
System.out.println("Your name is "+name+" and you live in "+ home+" ,"+state +".");
}
Output:
If the user inputs name="Gaus",city="LosAngeles" and state="California" then the output will be "Your name is Gaus and you live in LosAngeless, California."Explanation:
The above function is in java language which takes three argument names, state, and the city.The name will be stored on the name variable of the string type.The state will be stored on the state variable of string type.The city will be stored on the city variable of the string type.Then the Output will be displayed with the help of the print function.'+' is used to merge the string.Using your text editor, write the function sumSquares(aList). The function takes a list as an input and returns (not prints) the sum of the squares of the all the numbers which absolute value is divisible by 3. If an element in the list is not a number, the function should ignore the value and continue. When the function receives an input that is not a list, code should return the keyword None (not the string ‘None’). Hints: review the type() or isinstance() methods
Answer:
We have the Python code below with appropriate comments
Explanation:
#defining the function for use
def sumSquares(aList):
#checking if element in list is not in number as an error
if type(aList) is not list:
return 'error'
sum = 0
for x in aList:
#checking if in list and is
#divisible by 3
if type(x) in [int, float] and x % 3 == 0:
#squares of number x is x*x
#+= is an updating syntax that represents
#the sum of the squares
sum += x*x
#returning the sum, not printing
return sum
Sample test cases
print(sumSquares(5))
print(sumSquares('5'))
print(sumSquares(6.15))
print(sumSquares([1, 5, -3, 5, 9, 8, 4]))
print(sumSquares(['3', 5, -3, 5, 9.0, 8, 4, 'Hello']))

Explanation:
An input is taken and converted to int type as the input is of string type in python. It is checked if a number is divisible by 2 as if it is, then number is included because it is an even number and range() method is used which takes 3 numbers as parameters - start, end and step. If the step is -2 then 2 is subtracted every time from n. n is not included if it is not an even number.
Which of the following would not be a probable reason for choosing simulation as a decision-making tool?
Answer:
The correct answer is letter "B": There is a limited time in which to obtain results .
Explanation:
Decision-making tools allow entrepreneurs to analyze their companies from different angles thanks to the information provided. Market research, decision matrix, cost-benefit analysis, T-Charts, or SWOT (Strengths, Weaknesses, Opportunities, and Threats) Analysis are helpful for that purpose.
If a simulation is needed before going with the analysis itself, the time it could take is not specific. In case the company has a close deadline to decide on a topic, managers should avoid simulations and go ahead with the analysis but a deep evaluation of the results must be carried out to confirm accuracy.

#include <string.h> //header file
int main() //main function
{
char *word1 = NULL; //line 1 (as given in the question)
word1 = malloc(sizeof(char) * 11); //line 2
free(word1); //free the memory of pointer word1 line 3
word1 = "bramble"; //line 4
char *word2 = NULL; //line 5
word2 = malloc(sizeof(char) * 11); //line 6
free(word2); //free the memory of pointer word2 line 7
word2 = word1; //line 8
return 0; //line 9
}
Therefore, line 3 is the first line that introduce a memory leak anf after that line 7 introduce it in a program.

Explanation:
Using Parallels Desktop, Virtual box or the VMware Fusion to run Windows on a VM (virtual machine) inside the macOS. This technique allows the simultaneous running of Windows and mac programs, although the virtual machine doesn't quite accept as many Windows features as a double-boot configuration.Therefore, this will be the right answer.
Type a statement using srand() to seed random number generation using variable seedVal. Then type two statements using rand() to print two random integers between 0 and 9. End with a newline. Ex:
5
7
Note: For this activity, using one statement may yield different output (due to the compiler calling rand() in a different order). Use two statements for this activ
Answer:
The C++ code is given below with appropriate comments
Explanation:
//Use stdafx.h for visual studio.
#include "stdafx.h"
#include <iostream>
//Enable use of rand()
#include <cstdlib>
//Enable use of time()
#include <ctime>
using namespace std;
int main()
{
//Note that same variable cannot be defined to two
//different type in c++
//Thus, use either one of the two statement
//int seedVal=0;time_t seedVal;
//int seedVal=0;
time_t seedVal;
seedVal = time(0);
srand(seedVal);
//Use rand to generate two number by setting range
// between 0 and 9. Use endl for newline.
cout << (0 + rand() % ((10 - 0) + 0)) << endl;
cout << (0 + rand() % ((10 - 0) + 0)) << endl;
//Use for visual studio.
system("pause");
return 0;
}
To seed the random number generator, use srand(seedVal);. To generate and print two random integers between 0 and 9, use two separate calls to rand() % 10 with a newline character at the end of each print statement.
To seed the random number generator using srand(), you would use the variable seedVal as follows:
srand(seedVal);Then to print two random integers between 0 and 9, you should call rand() twice using separate statements and utilize the modulus operator to ensure the numbers fall within the desired range:
printf("%d\n", rand() % 10);Each call to rand() should be followed with a newline character for clear output separation.

How are these difficulties overcome?
Final answer:
When a computer is only capable of manipulating integers, difficulties arise with decimal numbers. However, these difficulties can be overcome by using different data types and algorithms. Programming languages and libraries provide tools to handle decimal numbers accurately.
Explanation:
When a computer is only capable of manipulating and storing integers, difficulties arise when working with numbers that involve decimal points or fractions. This is because computers work with binary numbers, which only consist of the digits 0 and 1. Decimal numbers cannot be represented directly in binary notation.
However, these difficulties can be overcome by using different data types and algorithms. For example, floating-point numbers can be used to represent decimal numbers in a binary format. Algorithms can be developed to perform mathematical operations on these floating-point numbers, allowing computers to work with a wider range of numeric values.
Programming languages and libraries provide built-in functions and methods to handle decimal numbers and perform arithmetic operations accurately. By using these tools, computer programmers can effectively work with integers, as well as decimal numbers, without losing accuracy.

write a java program that will print out the following pattern 1 12 123 1234 12345
Answer:
public class Main {
public static void main(String[] args)
{
int n,m;
int k=5;
for(n=1;n<=k;n++)
{
for(m=1;m<=n;m++)
System.out.print(m);
System.out.print(" ");
}
}
}
Explanation:
The solution to this problem is the use of nested loops of an inner and outer loop to generate a half pyramid of numbers, but displayed on the same line so we have a sequence 1 12 123 1234 12345. The outer loop iterates for n=1 to n<=5 and the inner loop that has the print statement prints the integers from for m = 1 to m<=n.
Note that the value k = 5 is hard coded which in some sense is the number of rows, that is the length of iteration of the outer loop.
The returns on assets C and D are strongly correlated with a correlation coefficient of 0.80. The variance of returns on C is 0.0009, and the variance of returns on D is 0.0036. What is the covariance of returns on C and D?A) 0.03020.B) 0.00144.C) 0.40110.D) 1.44024.
Answer:
Option (B) 0.00144
Explanation:
Data provided in the question:
Correlation coefficient, r = 0.80
Variance of returns on C = 0.0009
Variance of returns on D, = 0.0036
Now,
r = Cov(C,D) / (σA x σB)
Thus,
covariance of returns on C and D, Cov(C,D) = r × (σA x σB)
also,
σA = (0.0009) × 0.5 = 0.03 [ Since there are two assets, weight = 0.5 ]
σB = (0.0036) × 0.5 = 0.06
Therefore,
covariance of returns on C and D, Cov(C,D) = 0.8 × 0.03 × 0.06)
or
covariance of returns on C and D = 0.00144
Hence,
Option (B) 0.00144

Please, justify your answer.
a) if (1+2=3) then x:=x+1
b) if ((1+1=3) OR (2+2=3)) then x:=x+1
c) if ((2+3=5) AND (3+4=7)) then x:=x+1
Answer:
x=2
x=1
x=2
Explanation:
a)
This if statement if (1+2=3) checks if the addition of two numbers 1 and 2 is true. Here the addition of 1 and 2 is 3 which is true. So the condition becomes true.
Since the condition is true x:=x+1 statement is executed. This statement means that the value of x is incremented by 1.
The value of x was 1 before the if statement is reached. So x:=x+1 statement will add 1 to that value of x.
x:=x+1 means x=x+1 which is x=1+1 So x=2
Hence value of x is 2 (x=2) after the execution of x:=x+1
b)
In statement b the value of x will be 1 because both the mathematical operations in the if statement evaluate to false.
which means in b, x:=x+1 will not be executed and value of x remains unchanged i.e x=1
In (c) the value x will be 2 because the condition in the if statement is true. Both mathematical expressions 2+3=5 and 3+4=7 are true. Therefore x:=x+1 will be executed and value of x will be incremented by 1. Hence x=2

In the given problem we have a function void calc which takes two input arguments a and b and updates its values according to following equations
c = a + 2;
a = a * 3;
b = c + a;
Then we call this function calc(x,y) by providing test values of
int x = 1;
int y = 2;
int z = 3;
and the output returns the values of x, y and z
cout << x << " " << y << " " << z << endl;
Lets find out what is happening here!
When the program runs we provide x=a=1 and y=b=2
c=a+2=1+2=3
a=a*3=1*3=3
b=c+a=3+3=6
So the updated values of a=x=3 and b=y=6?
NO!
The updated values are a=x=1 and b=y=6
WHY?
There are two ways to pass values
1. Pass by values -> value cannot change (int a)
2. Pass by reference -> value can change (int& b)
Look at the function void calc (int a, int& b) ;
Here we are passing (int a) as a value and (int& b) as a reference, therefore x remains same x=1 and y gets changed to updated value y=6 and z remains same as z=3 since it wasnt used by function calc(x,y)
The right answer is:
b. 1 6 3
x=1, y=6, z=3
