amm1812

Answer:

Option (A) is the right answer.

Explanation:

According to the scenario, the user system is giving the error of invalid certificate while other users on the same network do not report any error, which means that there is some problem in a particular system.

Date and time can also be one of the main cause of this error because wrong date and time creates problem in surfing many websites by giving certificate error.

Hence the most appropriate answer is option (A).

While other option are wrong because of the following reasons:

  • UEFI boot mode is mainly used in booting the operating system and has no connection with network.
  • Logon time is also wrong because if the problem is with the login server, it can not give certificate error.
  • User access control is also not correct because it is used to control the access of the user.

Write a python application that allows a user to enter any number of student test scores until the user enters 999. If the score
Kryger [21]

Answer:

This program is as follows

<em>total = 0; count = 0</em>

<em>testscore = int(input("Score: "))</em>

<em>while testscore != 999:</em>

<em>    if testscore < 0 or testscore > 100:</em>

<em>        print("Out of range")</em>

<em>    else:</em>

<em>        total+=testscore</em>

<em>        count+=1</em>

<em>    testscore= int(input("Score: "))</em>

<em>print(count,"scores entered")</em>

<em>print("Arithmetic Average:",total/count)</em>

Explanation:

This initializes total and count to 0

total = 0; count = 0

This gets input for score

testscore = int(input("Score: "))

The following iteration stop when 999 is entered

while testscore != 999:

This prints out of range for scores outside 0 - 100

   if testscore < 0 or testscore > 100:

<em>        print("Out of range")</em>

Otherwise

   else:

The total score is calculated

       total+=testscore

The number of score is calculated

       count+=1

Get another input

   testscore = int(input("Score: "))

The number of score is printed

print(count,"scores entered")

The average of score is printed

print("Arithmetic Average:",total/count)
