Answer:
First Equation: 
Step-by-step explanation:
From the given number line we can see that there are 6 arrows/jumps of equal sizes to reach from 0 to 
Each small jump is equivalent to  . This is because from 0 to
. This is because from 0 to  there are 2 jumps, so 1 jump will be equal to
 there are 2 jumps, so 1 jump will be equal to  divided by 2 which is equal to
 divided by 2 which is equal to 
From 0 to  , 6 jumps of
, 6 jumps of  are made. In other words we can say
 are made. In other words we can say  is added to itself 6 times to reach to
 is added to itself 6 times to reach to  .
.
Adding  6 times to itself also means multiplying
 6 times to itself also means multiplying  by 6. So we can set up the equation as:
 by 6. So we can set up the equation as:

Dividing both sides by  we get:
  we get:

Hence, the first equation represents the given number line.
 
        
                    
             
        
        
        
540 points, 
15 points for the first, 30 for the second, 45, 60, 75, 90, 105, 120 for the eighth, added up it equals 540

Answer:
0.25
0.65
Step-by-step explanation:
Looking at the question, we can see that we were not given the probability of selecting a yellow ball.
Hence the probability of this is;
1-0.35-0.4 = 1-0.75 = 0.25
The probability that the selected ball is yellow is 0.25
The probability that it is not red means it is either yellow or green
What this means is that we add the probability of yellow to the probability of green
= 0.25 + 0.4 = 0.65
