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
Answer:
It's the last choice: 2x^2 - 5x - 8 - 37/(x - 5).
Step-by-step explanation:
Long division:
2x^2 - 5x -8 <---------------Quotient
---------------------------------
x - 5 ) 2x^3 - 15x^2 + 17x + 3
2x^3 - 10x^2
- 5x^2 + 17x
- 5x^2 + 25x
- 8x + 3
- 8x + 40
-37 <------ Remainder.
Dependent: Ventus has a bag of chex mix and he spent his time counting and organizing the food. There are 13/31 white pieces of chex, 10/31 pretzels, and 8/31 cracker bites. he wants to see if he can grab two white chex pieces, one at a time without replacing the first attempt. He reaches his hand into the bag and gets a white chex piece and doesn't replace it. What is the probability that Ventus will grab another white chex?
independent: Cabel has a bowl of fruit and his sister won't let him take one and look at it for some strange reason/ however, she does tell him the probability of picking each fruit out of 12. 2/6 oranges, 3/12 apples, and 5/12 bananas. He must replace every fruit he picks. What is the probability of picking an orange?
