Answer:
This seems to be related to MS Excel, here we will discuss the related formula:
<u>=IF(VLOOKUP("Adam Moriarty",$B$3:$C$5,2)>23,"Yes","No")</u>
the name can also be written in adjacent to J2 cell i.e. I2 and its reference to be used in vlookup primary key as follows:
<u>=IF(VLOOKUP(I2,$B$3:$C$5,2)>23,"Yes","No")</u>
Explanation:
We have used simple IF function combined with VLOOKUP function to reference this formula to the table of names and ages of the members (here the table is $B$3:$C$5 and ages are mentioned in 2nd column of the table)

Answer:
Hi there Foodalexandre! The question is good to revise knowledge on the concepts of classes and inheritance. Please find the answer with explanation below.
Explanation:
We can use a number of different object-oriented programming languages to implement this solution in, such as Java, C++, Ruby, etc. I have chosen to use Python as the language to implement because of the ease with which it can be used. First, I have defined the Vehicle class based on the description from the question, where the constructor (the __init__ method) initializes the door count and the engine sound, and the original Move() method belonging to the Vehicle class is defined. Then I define the Car class which inherits from the Vehicle class making it inherit the Vehicle properties, and initialize the Car class to have door count of 4 and engine sound as 'rrrrrr'. Defining the Move() method again in the Car class overrides the one in the Vehicle class, and the RoadTrip() method is added to return the string as requested in the question.
class Vehicle(object):
def __init__(self, door_count, engine_sound):
door_count: door_count
engine_sound: engine_sound
def Move()
:
return ‘rrrrrr’
class Car(Vehicle):
def __init__(self, door_count, engine_sound):
super().__init__(4, ‘rrrrrr’)
def Move():
return ‘vrumm’
def RoadTrip()
:
return “Not a care in the world”
I don't know but I am guessing 666 or 777 or 888.
