Answer: Choice A
The notation P(15,10) refers to the equation
P(n,r) = (n!)/(n-r)!
where n = 15 and r = 10. So,
P(15,10) = (15!)/(15-10)!
P(15,10) = (15!)/(5!)
which is close to the original expression but it is missing the 10! part in the denominator. Instead you'll use a combination formula
Answer:
y = 90x + 14
The slope intercept form is:
y = mx + b
the y in this case is the total cost
the m is the cost per hour (dependant)
the x is the number of hours
the 14 is the added cost of life jackets (independant)

To solve this problem we are going to set Python as the language.
books = ["a", "b", "c", ... , "z"]
selection = list(3) #here we set a list of dimension 3 as 3 are supposed to be selected
for book in books: #here we parse into the books list
If book in selection: continue #in order to obtain different books, if the book #already in selection list, then we jump
selection.append(random.choice(books)) #if not, we add the book to #selection
print(selection)
