Answer:
2 because id you take 3 times 2 its 6 divided by 3 is 2
Answer:
0, 5/4
Step-by-step explanation:
If 
, you get 0=0, which is obviously true.
As long as K is not 0, you can divide by k and get 
which is solved by 
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
First, we draw our line.
|------------------------------------------------------------------------------------|
a e
Next, break up this line into segments using the information.
|----------------------|----------------------|--------------------|------------------|
a b c d e
The entire line is 29.
ab + bc + cd + de = ae
ab + bc + cd + de = 29
You also know that
bd = bc + cd
Due to midpoint theorem,
ab = bc
cd = de
Then,
2ab + 2cd = 29
The equations we will use are
bd = bc + cd eq1
2bc + 2cd = 29 eq2
Dividing both sides of the equation in eq2 yields
bc + cd = 14.5
bd = bc + cd
bd = 14.5
You need to distribute the numerical factors for each term in the parenthesis:
This equals
