SVETLANKA909090 [29]

Answer:

Written in C++

bool checkfloor(double num1, double num2, double num3) {

   if(floor(num1 * num2) == floor(num3)){

       return true;

   }

   else {

       return false;

   }

}

Explanation:

The function written in C++

This line defines the function

bool checkfloor(double num1, double num2, double num3) {

The following if condition checks if the floor of num1 * num2 equals num3

   if(floor(num1 * num2) == floor(num3)){

       return true; It returns true, if yes

   }

   else {

       return false; It returns false, if otherwise

   }

}

lisov135 [29]

# Write a function called mul_time that takes a Time object and a number and

# returns a new Time object that contains the product of the original Time and

# the number.

# Then use mul_time to write a function that takes a Time object that

# represents the finishing time in a race, and a number that represents the

# distance, and returns a Time object that represents the average pace (time

# per mile).

# Current Status: Complete

class Time(object):

   """ represents the time of day.

   attributes: hour, minute, second"""

time = Time()

time.hour = 3

time.minute = 0

time.second = 0

def time_to_int(time):

   minutes = time.hour * 60 + time.minute

   seconds = minutes * 60 + time.second

   return seconds

def int_to_time(seconds):

   new_time = Time()

   minutes, new_time.second = divmod(seconds, 60)

   time.hour, time.minute = divmod(minutes, 60)

   return time

def mul_time(time, multicand):

   time_int = time_to_int(time) * multicand

   new_time = int_to_time(time_int)

   if new_time.hour > 12:

       new_time.hour = new_time.hour % 12

#    print ("New time is: %.2d:%.2d:%.2d"

Answer:

By supplying a variety of charts and graphs to present the information in best way.

By tracking and analyzing the data

By conveying large amount of numerical data in more understandable format.

Explanation:

You need to know the limitations of Excel software. You will find that it does not support more than 3 variables while analyzing. However, if you use analytic software like Tableau and Microsoft Power BI then you can use a lot number of variables. And this is done through graphs and charts, and the other variables apart from x, y, z are the colors, shades. etc. Even color alone can add a good number of variables, and hence you can understand. Thus, you will be able to query better. Queries become better if you have more variables. And charts and graphs always present the information in the best way/ Also you can track and analyze the data. And through it conveying a large amount of numerical data in a more understandable format is made possible, and this is definitely quite helpful. Hence, all of the options mentioned above are helpful. But they do not do complex calculations and complex queries in fact.
