In this Java program, we read a CSV file named "printers.csv" that contains printer information. Each line in the file represents a printer, and the values are separated by commas (`,`).
We split each line into an array of strings using the `split()` method and access the relevant printer information. In this case, we retrieve the device name (`printerInfo[0]`), black cartridge level (`printerInfo[5]`), and color cartridge level (`printerInfo[6]`).
We then check if either the black cartridge level or color cartridge level is below 10%. If so, we notify the user by printing a message. You can modify this code to send a notification through email, SMS, or any other preferred method.
Remember to update the `csvFile` variable with the correct file path of your CSV file before running the program.

AP CSP - Write a program that takes 10 random numbers from 1 to 12 inclusively and averages them together.
Here is the code I wrote: (Python)
print(random() * 12 + 1)
1. What is the code supposed to be?
2. What is wrong with my code?
Answer:
follows are the correct python code to this question:
import random as r#import random package as r
import statistics as s #import statistics package as s
l= r.sample(range(0,12),10)#defining l variable that use random function to store 10 random numbers
avg= s.mean(l)#defining avg variable for calculate average of l
print('List of random number are: ', l)#print list of random numbers
print("The random number Average is: ", avg)#print average value
Output:
List of random number are: [4, 10, 6, 0, 3, 5, 1, 7, 11, 2]
The random number Average is: 4.9
Explanation:
In question 1:
In the given code, two packages are imported, which are "random and statistics", in which "random" is used to generate a random number, and "statistics" is used to calculate the average value.
In the code, the "l" variable is used, which uses a random function and store 10 random numbers, and an "avg" variable is defined that calculates the average value. In the last step, the print method is used that print number and its average value.
In question 2:
The given code is wrong because it only calls the "random" method, which is not defined.
The program illustrates the use of random module.
Your program is wrong in the following ways
You didn't import the random moduleWrong usage of randomThe required mean is neither calculated , nor printedThe correction program in Python where comments are used for explanation is as follows:
#This imports the random module
import random
#This initializes an empty list
myList = []
#This initializes total (i.e. sum) to 0
total = 0
#This iterates through the list
for i in range(0,10):
#This generates a random number
num = random.randint(0,12)
#The number is then appended to the list
myList.append(num)
#This calculates the sum of all random numbers
total += num
#This calculates and prints the average
print("The random number Average is: ", total/12.0)
At the end of the program, the mean of all random numbers is. calculated and printed

Nicotine in menthol cigarettes 90% confidence; n=26, s=0.27 mg. df= (Type a whole number.) χ2L= (Round to three decimal places as needed.)
The number of degrees of freedom is df = n - 1 = 26 - 1 = 25. The critical values χ2L and χ2R depend on the confidence level desired and the degrees of freedom. Since a 90% confidence interval is required, we need to find the critical values corresponding to α = 0.1 (10% significance level) on both sides of the chi-square distribution with 25 degrees of freedom. The critical values χ2L and χ2R are found using a chi-square table or a statistical software.
What are the critical values χ2L and χ2R for a 90% confidence interval with 25 degrees of freedom?To find the critical values, we can use a chi-square table or a statistical software. From the chi-square table, the critical values for a 90% confidence interval with 25 degrees of freedom are χ2L = 12.401 and χ2R = 38.885 (rounded to three decimal places).

Which of the following are advantages of a local area network, as opposed to a wide area network? Select 3 options. Responses higher speeds higher speeds provides access to more networks provides access to more networks lower cost lower cost greater geographic reach greater geographic reach more secure more secure
The advantages of a local area network (LAN) over a wide area network (WAN) include higher speeds, lower cost, and greater security.
Advantages of a local area network (LAN) over a wide area network (WAN) can be summarized as follows:
Higher speeds: LANs typically offer faster data transfer rates compared to WANs. Since LANs cover a smaller geographical area, they can utilize high-speed technologies like Ethernet, resulting in quicker communication between devices.Lower cost: LAN infrastructure is generally less expensive to set up and maintain compared to WANs. LANs require fewer networking devices and cables, and the equipment used is often more affordable. Additionally, WANs involve costs associated with long-distance communication lines and leased connections.More secure: LANs tend to provide a higher level of security compared to WANs. Since LANs are confined to a limited area, it is easier to implement security measures such as firewalls, access controls, and encryption protocols to protect the network from unauthorized access and external threats.To summarize, the advantages of a LAN over a WAN are higher speeds, lower cost, and enhanced security.
