It depends on the problem. If you are solving a conplex one or simple
Answer:
bill = float(input("Enter the bill amount: "))
rating = int(input("Choose a rating: 1 = Totally satisfied, 2 = Satisfied, 3 = Dissatisfied.: "))
if rating is 1:
tip = bill * 0.2
elif rating is 2:
tip = bill * 0.15
elif rating is 3:
tip = bill * 0.1
print("The rating is: " + str(rating))
print("The tip is: $%.2f" % (tip))
Explanation:
*The code is in Python
- Ask the user for the <em>bill</em> and <em>rating</em>
- Depending on the <em>rating</em>, calculate the <em>tip</em> using <u>if else</u> statement i.e. If the rating is chosen as 1, calculate the tip by taking 20 percent of the bill.
- Print the <em>rating</em> and the <em>tip</em>
Answer:
<u>720</u> possible PIN can be generated.
Explanation:
To calculate different number of orders of digits to create password and PIN, we calculate permutation.
Permutation is a term that means the number of methods or ways in which different numbers, alphabets, characters and objects can arranged or organized. To calculate the permutation following formula will be used:
nPr = n!/(n-r)!
there P is permutation, n is number of digits that need to be organize, r is the size of subset (Number of digits a password contains)
So in question we need to calculate
P=?
where
n= 10 (0-9 means total 10 digits)
r= 3 (PIN Consist of three digits)
So by using formula
10P3 = 10!/(10-3)!
=10!/7!
= 10x9x8x7!/7!
= 10x9x8
= 720
It's D because a checklist is to help you organize a list of things like groceries, homework etc. It can sperate indormation..for example, homework need to be separated so we won't messed up on which is which. It can also portray information clearly because you're making a check list.
Quality control is a system of maintaining standards in manufactured products by testing a sample of the output against the specification.
