<span>i  Ace</span>hello :
let : A(-6,6)  B(6,-2)
the center is w((-6+6)/2 , (6-2)/2)....(midel <span>[ AB]
w(0 ,2)
the ridus is : r = AB/2
AB = </span>√(-6-6)²+(6+2)² = √(144+64) =<span>√208/2
</span>an equation in <span>standard form equation of the circle :
</span>(x+0)²+(y-2)² =  (√208/2)²=208/4 = 52
        
                    
             
        
        
        
The experimental probability that in a group of 4 students, at least one of them has brown eyes is 95%.
<h3>
What is Experimental Probability?</h3>
Experimental probability is a probability that is determined on the basis of a series of experiments. A random experiment is done and is repeated many times to determine their likelihood and each repetition is known as a trial. The experiment is conducted to find the chance of an event to occur or not to occur.
Here , Favorable Outcome = 19
           Total outcomes = 20
Probability = Favorable Outcome/ Total Outcome
                    = 19 / 20
                    = 95%
Thus, the experimental probability that in a group of 4 students, at least one of them has brown eyes is 95%.

Answer:
The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere.So following options are correct options
-  slowly increasing global temperature
- caused when atmospheric gases trap heat
- increasing because of carbon dioxide emissions
 
        
             
        
        
        
Answer:

Explanation:
Let's begin writing down everything
(X×(-11)+5)×(-9)+X-55 
Now we can multiply
-9(-11X+5)+X-55
99X-45+X-55
And so we get
100X-100
Factorize 100
100(x-1)
