Answer:
The program to this question can be given as follows:
Program:
#defining variable quarters, dimes, and nickels.
quarters=int(input("Enter value of quarters: ")) #input value by user dimes=int(input("Enter value of dimes: ")) #input value by user nickels=int(input("Enter value of nickels: ")) #input value by user
#defining variable pennies
pennies = ((25*quarters)+(10*dimes)+(5*nickels))
#calculate value in pennies variable
print('Total number of coins in pennies is: ',pennies)#print value
Output:
Enter value of quarters: 3
Enter value of dimes: 2
Enter value of nickels: 1
Total number of coins in pennies is: 100
Explanation:
In the above python program code, firstly three variable "quarters, dimes, and nickels", all of these variable uses input function, that is used to take input value from the user side, in these variable, an int is used that defined, that user input only integer value.
- After taking input from the user a new variable "pennies" is defined, which is uses the user input values and calculates its addition.
- In the next line, print function is used, which uses variable "pennies" to print its calculated value.
Answer:
=DSUM(A4:D8, "Unit Cost", A1:B2)
Explanation:
From the list of given options, it's obvious that the question relates to Excel database sum function.
The correct answer among the list of options is:
=DSUM(A4:D8, "Unit Cost", A1:B2)
Where
DSUM represents the function itself
A4:D8 represents the range
"Unit cost" represents the field
and
A1:B2 represents the criteria of the function
Analysing other options:
Option 1: The equality sign (=) before excel formulas is missing
Option 2: Sum is used instead of DSUM and there's a missing bracket before the range
Option 3: There's a missing comma between the range, the field and the criteria
Hence, the last option (4) answers the question.
