Consider the following code segment, which is intended to store the sum of all multiples of 10 between 10 and 100, inclusive (10 20 ... 100), in the variable total.
int x = 100;int total = 0;while( /* missing code */ ){total = total + x;x = x - 10;}Which of the following can be used as a replacement for /* missing code */ so that the code segment works as intended?A. x < 100.B. x <= 100.C. x > 10.D. x >= 10.E. x != 10.

Answers

The code segment illustrates the use of while loops

Loops are program statements that are used for repetitive and iterative operations

The missing statement in the code is x>= 0

The code is meant to add numbers from 10 to 100 (inclusive) with an increment of 10.

At the beginning of the program, variable x is initialized to 100, and it is reduced by 10 in the iteration until it gets to 10

So, the condition must be set to stop when the value of x is 10 i.e. x >= 0

i.e. the iteration must be repeated while x is greater than or equal to 10

Hence, the missing statement is (d) x >= 0

AI is not embraced everywhere in every industry because _______.

Answers

Answer:

See below:

Explanation:

AI is not embraced in every industry because of the type of industry and what it requires. In some situations, a human is needed since an AI cannot determine what to do and can sometimes even cause death.

AI isn't embraced everywhere because for some things we need a person, lets say for example, we need an AI to respond to 911 calls, that simply won't work due to the many situations and training the bot too will be a nightmare. For example, if a caller says a word that normal humans can understand, or a "code word" that every human knows but they haven't bothered to tell the bot, that will be the end of the line for them.

There are mutliple reasons to not use AI depending on the situation whether its life and death or just plain impractical.
