Answer:

8/15

Step-by-step explanation:

The probability of 1 white counter in the two draws is ...

p(1 white) = p(1st white & 2nd not) +p(1st not & 2nd white)

= (6/10)(4/9) +(4/10)(6/9) = (24+24)/90 = 8/15

The probability that only one of the counters is white is 8/15.

__

<em>Alternate solution</em>

There are 10C2 = 45 ways to draw 2 counters. Of these, there are 6C2 = 15 ways to draw 2 white counters, 4C2 = 6 ways to draw 2 non-white counters, and (6C1)(4C1) = 24 ways to draw 1 white counter. The probability of drawing 1 white counter in the two draws is 24/45 = 8/15.

If f(x) = 5x − 3, which expression represents its inverse function?

tangare [24]

Answer:

$f ^{-1}(x)=\frac{x+3}{5}$

Step-by-step explanation:

To find the inverse of a function f (x) follow the steps below:

1) Make y = f (x)

$y= 5x - 3$

2) Solve for the variable x

$y+3= 5x - 3+3$

$y+3= 5x$

$x=\frac{y+3}{5}$

3) Exchange the variable x with the variable y

$y=\frac{x+3}{5}$

4) Make $y = f ^{-1}(x)$

$f ^{-1}(x)=\frac{x+3}{5}$

Finally, the inverse of the function f (x) is: $f ^{-1}(x)=\frac{x+3}{5}$
