Answer:
The correct option is D = regionNumber
Explanation:
In this scenario we want to know customers who owe more than $1000 each, in each of 12 sales regions. And the customer data variables include name, zip-code, balanceDue and regionNumber; based on the customer data variables names and zip-code will not really affect our output. It is based on balanceDue that we increment the number of customer owing in a particular region (regionNumber).
Therefore, we would add 1 to an array element whose subscript would be represented by regionNumber since we are interested to know the number of customer owing in each of the 12 sales regions.
Answer: Rich medium
Explanation: A communication is said to be rich id it provides the services like observing the body language, immediate communication, instant judging of the voice tone etc. These factors are commonly found in the face to face interaction which is considered as the rich source of communication. It is considered as rich medium because it has the capability of receiving the output immediately .
The answer would be Assembly language as assembly language is not used for web development, but rather is a low level programming language.

Answer:
The probability that among three randomly selected Internet users, at least one is more careful about personal information when using a public Wi-Fi hotspot is 0.964
If the survey subjects <em>volunteered</em> to respond , then those with the strongest opinions are most likely respond. The survey sample is then not randomly selected, the survey may have a <em>response bias.</em>
Explanation:
Let P(at least one is more careful about personal information when using a public Wi-Fi hotspot) denote the probability that among three randomly selected Internet users, at least one is more careful about personal information when using a public Wi-Fi hotspot, then we have the equation
P(at least one is more careful about personal information when using a public Wi-Fi hotspot) = 1 - P(none of the selected users is more careful about personal information when using a public Wi-Fi hotspot)
- If 67% of Internet users are more careful about personal information when using a public Wi-Fi, then 33% of them are not.
P(none of the selected users is more careful about personal information when using a public Wi-Fi hotspot) =
≈ 0.036
P(at least one is more careful about personal information when using a public Wi-Fi hotspot) = 1 - 0.036 = 0.964
