AI is not embraced everywhere in every industry because _______.
Nitella [24]

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.

Write a program that prints the Grade based on the given data. 95-100: A+ 90-94: A 80-89: B+ 70-79: B 60-69: C+ 50-59: C &lt;49
mr Goodwill [35]

Answer:

The program to this question as follows:

Program:

score=int(input("Enter your percentage: ")) #input grade by user

#using conditional statement for match condition  

if 95<=score <= 100: #if value in between 95 to 100

   grade = 'A+' #assign grade

elif 90 <=score <= 94: #elif value in between 90 to 94

   grade = 'A' #assign grade

elif 80 <=score <= 89:  #elif value in between 80 to 89

   grade = 'B+' #assign grade

elif 70 <=score <= 79:  #elif value in between 70 to 79

   grade = 'B' #assign grade

elif 60 <=score <= 69:  #elif value in between 60 to 69

   grade = 'C+' #assign grade

elif 50 <=score <= 59:  #elif value in between 50 to 59

   grade = 'C' #assign grade

elif score<49 :  #elif value is less then 49

   grade = 'F' #assign grade

print (grade) #print grade

Output:

Enter your percentage: 50

C

 Explanation:

In the above python code, a variable "score" is defined, this variable is used for taking value from the user end. In the next step if-elif-else conditional statement is used, this statement is used when a group of statements is given in which one is true. The if block check score value is between 95-100 if this is true it will print A+.

In elif block if the above condition is not true, then this condition will execute, in this block, there are multiple elif block is used that can be described as follows:

  • In the first block, if the value in between 90-94. It will print A.
  • In the second block, if the value in between 80-89. It will print B+.
  • In the third block, if value in between 70-79. It will print B.
  • In the fourth block, if value in between 60-69. It will print C+.
  • In the fifth block, if value in between 50-59. It will print C.
  • In the last, if the value of the score is less then 49. It will print F.

Write two separate formulas using different commands that concatenate " john and "smith" together to form " John Smith"
VladimirAG [237]

Answer:

1. =CONCATENATE(" John"," ","Smith")

2. =(" John"&" "&"Smith")

Explanation:

Given

Two separate strings; "John" and "Smith"

Required

2 separate formulas to concatenate both strings to form " John Smith"

There are several ways to concatenate strings in Microsoft Office Excel; one of the methods is using the concatenate function while the another method is using the traditional & operator.

Using the concatenate function, the formula is as follows

=CONCATENATE(" John"," ","Smith")

This function will combine the " John", " " and "Smith" to give a new string " John Smith" (without the quotes).

Using the traditional & operator may be a little bit difficult (and not frequently used) but the formula is as follows;

=(" John"&" "&"Smith")

The result will be the same as (1) above
