Answer:

C. Wait for about 30 minutes for the system to cool downand try again.

Explanation:

In computer system troubleshooting, there are two areas where problems can arise. They are hardware and software related issues.

software issues are application related like an application not installed properly, malicious software attack, corrupted operating system etc, while hardware has to do with a faulty hardware component in the system.

Example of a hardware related issue, when the active fan is faulty, the computer overheat and eventually shuts down to cool the system. When it cools down, the computer can boot again.

To confirm that the fan is faulty, when it shuts down to cool, wait for some time and try booting the system again. If it comes on, then the fan is bad.

   for s in sentence:

       s = s.lower()

       if s.isalpha():

           count += 1

       if s == "e":

           e_count += 1

   return "The text contains " + str(count) + " alphabetic characters, of which " + str(e_count) + " (" + str(e_count*100/count) + "%) are ‘e’."

Explanation:

Create a function called analyze_text takes a string, sentence

Initialize the count and e_count variables as 0

Create a for loop that iterates through the sentence

Inside the loop, convert all letters to lowercase using lower() function. Check each character. If a character is a letter, increment the count by 1. If a character is "e", increment the e_count by 1.

The code is as follows

Code:

<em>AIS=input('Please enter the AIS array of the form [AIS1 AIS2 AIS3 AIS4 AIS5 AIS6]');%taking input of the array</em>

<em>AISs=sort(AIS,'descend');%sorting the array in the descending order</em>

<em>iss=(AISs(1,1)^2)+(AISs(1,2)^2)+(AISs(1,3)^2);%Calculating the ISS</em>

<em>disp(['The injury severity score (ISS) for the entered array is ', num2str(iss)])%Displaying the output</em>

Output:

<u><em>Please enter the AIS array of the form [AIS1 AIS2 AIS3 AIS4 AIS5 AIS6][3 0 4 5 3 0];</em></u>
