Answer:

P(1 and 2 are green) = 3/25

Step-by-step explanation:

We need to know the total number of marbles

6 Blue + 10 red + 9 green = 25 marbles

P ( 1st marble is green) = green/ total

                                       = 9/25

Since we don't put it back, there are  

6 Blue + 10 red + 8 green = 24 marbles

P ( 2st marble is green) = green/ total

                                       = 8/24  = 1/3

P(1 and 2 are green) = P(1st green) * P(2nd green)

                                  = 9/25 * 1/3

                                   = 3/25

Given the recursive formula:<br> a1=3<br> An=2(an-1+1)<br> Find a2 a3 a4
fenix001 [56]

Answer:

a_2 = 8

a_3 = 18

a_4 = 38

Step-by-step explanation:

We are given the following recursive formula:

a_n = 2(a_{n-1}+1)

And consider a_1 = 3

a2

a_2 = 2(a_1 + 1) = 2(3 + 1) = 8

a3

a_3 = 2(a_2 + 1) = 2(8 + 1) = 18

a4

a_4 = 2(a_3 + 1) = 2(18 + 1) = 38

Simplify the expression. (3x/y)^-3
AysviL [449]

Answer:

y^3/(27 x^3)

Step-by-step explanation:

Simplify the following:

((3 x)/y)^(-3)

((3 x)/y)^(-3) = (y/(3 x))^3:

(y/(3 x))^3

Multiply each exponent in y/(3 x) by 3:

(y^3)/((3 x)^3)

Multiply each exponent in 3 x by 3:

y^3/(3^3 x^3)

3^3 = 3×3^2:

y^3/(3×3^2 x^3)

3^2 = 9:

y^3/(3×9 x^3)

3×9 = 27:

Answer:  y^3/(27 x^3)
