The <em><u>correct answer</u></em> is:

Yes, it is proportional.

Explanation:

In this relationship, we can write the equation for altitude as y = 4000-200x, where y is the altitude and x is the number of minutes.  For every minute that the plane is in the air, the altitude changes the same number of feet; this means it is a proportional relationship.

Of 15 possible​ books, you plan to take 6 with you on vacation. How many different collections of 6 books can you​ take?
Mekhanik [1.2K]

Answer:

5005

Step-by-step explanation:

6 C 15

(6, 15)

15! / (6! x 9!)

The answer is 5005

C is just a way to say the order the books are picked in is random and ! means factorial. Factorial is when you multiply all the previous numbers up to the number it is. For example, 5! = 1 x 2 x 3 x 4 x 5 and 2! = 1 x 2
