Step-by-step explanation: IM DOING THE INTERIM TOOOOOO
 
        
             
        
        
        
(1-cos^2x/cosx)*cosecx
(sin^2x/cosx)*sinx   (where 1-cos^2x=sin^2x) and 1/cscx=sinx
sinx/cosx=tanx(divide by sinx)
hence proved
        
             
        
        
        
Answer:
(17,3)
Step-by-step explanation:
Equation 1.
x=5y+2
Equation 2.
x-4y=5
To solve with substitution, it looks like the x-variable in the first equation is already isolated. So, plug the first equation into the x-variable in the second equation. 
x-4y=5
(5y+2)-4y=5
y+2=5
y=3
Now that we found y, plug y into one of the equations to solve for x.
x=5y+2
x=5(3)+2
x=15+2
x=17

Answer:

Step-by-step explanation:
Given
Let

So:
 --- probability of O
 --- probability of O
 --- Number of spin
 --- Number of spin
Using the complement rule, the probability that a spin will not land on orange is:


Express as decimal


On two spins, the probability that it will not land on orange is:

So, we have:
