For Q2 it is just a simple matter of using a tree diagram for each possible outcome. So there are 4 black balls (B) and 2 white (W) and by using a tree diagram of the possible outcomes it comes to a 3 out of 5 points go to player 1 if B was drawn first and 2 go to player 2. If W was drawn first though, then player 1 gets 1 out of 5 points and 4 goes to player 2 and if you add up the probabilities at the end it comes to player 1 having a 14 out of 30 chance and player 2 having a 16 out of 30 chance therefore player 2 would have a better chance at winning and it isn't a fair game

So firstly, multiply both sides by t: $ta=v_1-v_0$

Complete the table of inputs and outputs for the given function. g(x)=-4x-1

Radda [10]

Answer:

(x, y) = (-2, 7), (0, -1), (3, -13), (-1, 3)

Step-by-step explanation:

To fill in the y-values, you need to put the x-value in the equation and evaluate.

for x=0

y = -4(0) -1 = -1

for x=-1

y = -4(-1) -1 = 4 -1 = 3

To fill in the x-values, we can solve for x and then do as we did above.

y = -4x -1

y +1 = -4x . . . . add 1

-(y +1)/4 = x . . . divide by -4

for y=7

x = -(7 +1)/4 = -2

for y=-13

x = -(-13+1)/4 = -(-12/4) = 3

Then the table is ...

$\boxed{\begin{array}{cc}x&g(x)\\-2&7\\0&-1\\3&-13\\-1&3\end{array}}$

1/4 x 2/5=

Zanzabum

Answer:

1/10

Step-by-step explanation:

The answer is 1/10 because multiply the numerator and got 2 and then the denomi actors and got 20.

So it would be 2/20.

Then you simplify 2/20 to 1/10

2÷2=1

20÷2÷10

Then you get 1/10.
