The correct answer is: D. name, credit card number, product number, and sales price

Although the database would have all the fields that she would need, it would still be better if the NAME field would be split into 2 or 3 parts. This is a practice that is done in the industry to keep information more clear as there are a couple of cases where people change their names due to different reasons.

________ are the primary means of authentication for a user's computer and other networks and servers to which the user may have
inn [45]

Answer:

The answer to this question is "Password".

Explanation:

In computer science, any User's computer and networks and server is secured with the password to access all we use the password. for example, if we want to access any WiFi system or any User's computer. Then we will insert the password. If the password is wrong so we can't access the WiFi system or User's computer. similarly, If we want to access any server so we must know about the password. Then we use the server and change it's setting.

So the password is the primary means of authentication for all User's.

For this problem, you will write a function standard_deviation that takes a list whose elements are numbers (they may be floats
Evgesh-ka [11]

Answer:

  1. import math  
  2. def standard_deviation(aList):
  3.    sum = 0
  4.    for x in aList:
  5.        sum += x  
  6.    
  7.    mean = sum / float(len(aList))
  8.    sumDe = 0
  9.    for x in aList:
  10.        sumDe += (x - mean) * (x - mean)
  11.    
  12.    variance = sumDe / float(len(aList))
  13.    SD = math.sqrt(variance)
  14.    return SD  
  15. print(standard_deviation([3,6, 7, 9, 12, 17]))

Explanation:

The solution code is written in Python 3.

Firstly, we need to import math module (Line 1).

Next, create a function standard_deviation that takes one input parameter, which is a list (Line 3). In the function, calculate the mean for the value in the input list (Line 4-8). Next, use the mean to calculate the variance (Line 10-15). Next, use sqrt method from math module to get the square root of variance and this will result in standard deviation (Line 16). At last, return the standard deviation (Line 18).

We can test the function using a sample list (Line 20) and we shall get 4.509249752822894

If we pass an empty list, a ZeroDivisionError exception will be raised.
