Answer:
2^3 * 5^2
Step-by-step explanation:
We need to break 200 down into prime numbers
200 = 20*10  These are not prime
        = 4*5  * 2*5    The 4 is not prime
        = 2*2*5  * 2*5  This is prime
Rearranging
        = 2*2*2*5*5
        = 2^3 * 5^2
 
        
             
        
        
        
Answer:
8.08 %
Step-by-step explanation:
Let us denote :  score X follows a normal distribution with mean
 score X follows a normal distribution with mean  and standard deviation
 and standard deviation 
Step 2
The probability that someone scored 21.9 or less is :

Substitute  , so that
, so that

Then the resulting ODE in  is separable, with
 is separable, with

On the left, we can split into partial fractions:

Integrating both sides gives




Now solve for  :

55 over 3, or 55 wrestlers for every 3 rounds, but the wrestlers value is negative, thus 55 "less" wrestlers for every 3 rounds on average.
