F (x) = 3r + 6. Find the inverse of f(x).

Levart [38]

Answer:

The inverse is 1/3x -2

Step-by-step explanation:

f (x) = 3x + 6

y = 3x+6

Exchange x and y

x = 3y+6

Subtract 6 from each side

x-6 = 3y+6-6

x-6 = 3y

Divide by 3

1/3x - 6/3 = y

1/3x -2 = y

The inverse is 1/3x -2

Answer:

$P(Sum = 9) = \frac{1}{9}$

Step-by-step explanation:

Given

Outcomes of rolling two dice

Required

P(Sum = 9)

From the given outcomes, we have:

$n(S) = 36$ -- the sample size

$Sum = 9:=\{(3,6),(4,5),(5,4),(6,3)\}$

So.

$n(Sum = 9) = 4$

The probability is:

$P(Sum = 9) = \frac{n(Sum = 9)}{n(S)}$

$P(Sum = 9) = \frac{4}{36}$

Simplify

$P(Sum = 9) = \frac{1}{9}$
