Step-by-step explanation:
Put the m value where m is
9/3+4
9/3 simplified is 3
3+4=7
 
        
                    
             
        
        
        
The fraction is 12/1000 which simplified to 3/250. The percentage is 1.2%.
        
                    
             
        
        
        
Answer:
61,239,550
Step-by-step explanation:
We let the random variable X denote the IQ scores. This would imply that X is normal with a mean of 100 and standard deviation of 17. We proceed to determine the probability that an individual chosen at random from the population would be a genius, that is;
Pr( X>140)
The next step is to evaluate the z-score associated with the IQ score of 140 by standardizing the random variable X;

The area to the right of 2.3529 will be the required probability. This area from the standard normal tables is 0.009314
From a population of 6,575,000,000 the number of geniuses would be;
6,575,000,000*0.009314 = 61,239,550
