How can i factor the expression below 9x2-1

answer:

step-by-step explanation: 9×2=18

18-1=17

anwser 17

answer:

= 11/4165

step-by-step explanation:

we are dealt 4 cards, so we will assume no replacement.

the first card:

there are 52 cards and 13 of them are diamonds

p(1st card is a diamond) = 13/52 = 1/4

the second card:

we have 1 card that is a diamond

there are 51 cards and 12 of them are diamonds

p(2nd card is a diamond) = 12/51

the third card:

we have 2 cards that are diamonds

there are 50 cards and 11 of them are diamonds

p(3rd card is a diamond) = 11/50

the fourth card:

we have 3 cards that are diamonds

there are 49 cards and 10 of them are diamonds

p(4th card is a diamond) = 10/49

p(all 4 cards are diamonds) =   p(1st card is a diamond) * p(2nd card is a diamond) * p(3rd card is a diamond) * p(4th card is a diamond)

                                              = 1/4 * 12/51 * 11/50 * 10/49

                                              = 11/4165

answer:

the numerator is greater than the deneminator

the definition of an improper fraction is a fractione that can be simplified to be greater than 1. for this to be true the numerator must be greater than the denominator
