Answer:

1/21

Step-by-step explanation:

Cards: 2,3,4,5,6,7,8 7 cards

1st card :5

P(5) = number of 5's / total

= 1/7

Then we keep the card

Cards: 2,3,4,6,7,8 only 6 cards left

card less than 4: 2,3

P (card less than 4) = number of cards less than 4/ total cards

= 2/6 = 1/3

P (5, no replacement, card less than 4) = P(5) * P( less than 4)

= 1/7 * 1/3

=1/21

Can someone help me please ???????

Inessa [10]

Answer:

d=1

Step-by-step explanation:

Factor d^2 - 2d - 8 into (d-4)(d+2)

Move -2/d+2 onto the other side, changing it into 2/d+2.

$\frac{-3d}{(d-4)(d+2)} +\frac{3}{d-4}+\frac{2}{d+2} = 0$

Let the empty side equal zero.

Add 3/d-4 and 2/d+2

$\frac{5d-2}{(d+2)(d-4)}$

Then add that to -3d.

$\frac{2d-2}{(d+2)(d+4)}$

Multiply 0 by d+2 and d-4 to get 2d-2 by itself.

2d=2

d=1

I can't edit the equation, but it's d-4 althroughout the question. Sorry for being so slow.

If g(x) = 3(x + 10), what is the value of the function when x = -8? O -8 -2 24

Gala2k [10]

Answer:

6 which is none of your answers.

Are you sure your function is right?

Is value to plug in x=-8?

Step-by-step explanation:

To find the value of the function at x=-8, you replace x with -8 in the function.

g(x)=3(x+10)

g(-8)=3(-8+10)

g(-8)=3(2)

g(-8)=6
