C r = (n!)/(r!(n-r)!)
9 C 3 = (9!)/(3!*(9-3)!)
9 C 3 = (9!)/(3!*6!)
9 C 3 = (9*8*7*6!)/(3!*6!)
9 C 3 = (9*8*7)/(3!)
9 C 3 = (9*8*7)/(3*2*1)
9 C 3 = (504)/(6) 9 C 3 = 84

What happens to the value of the expression as 50/p decreases from a large positive number to a small positive number?
Pepsi [2]

Answer:

50/p increases from a small positive number to a big positive number.

Step-by-step explanation:

p is in the denominator. This means that p and the value of the expression 50/p are inverse proportional. So for a big value of p, 50/p has a small positive value. For a small value of p, 50/p has a high positive value.

what happens to the value of the expression 50/p as p decreases from a large positive number to a small positive number?

50/p increases from a small positive number to a big positive number.

For example

gizmo_the_mogwai [7]
-5d – 16d + -14d + 8d – -13d = -14
-5d-16d-14d+8d+13d=-14
-21d-14d+8d+13d=-14
-35d+8d+13d=-14
-27d+13d=-14

solong [7]

Answer:

=64 %

The original price is 25

The new price is 9

Percent decrease = (25-9)/25 * 100%

                               =16/25 * 100%

                               =64 %
