for invested amount. 700 for 7 600 for 6 and for interest rate 2.8 for sample i dont know
 
        
                    
             
        
        
        
We first determine the z-scores for the given x-values of 64 and 96.
For x = 64: z = (64 - 80) / 8 = -2
For x = 96: z = (96 - 80) / 8 = 2
Therefore we find the probability that -2 < z < 2, which is around 0.95. Therefore, out of 100 students, approximately 100(0.95) = 95 students will weigh between 64 and 96 pounds.
        
             
        
        
        
Answer:
The balance is  
  
Step-by-step explanation:
we know that    
The compound interest formula is equal to  
 
  
where  
A is the Final Investment Value  
P is the Principal amount of money to be invested  
r is the rate of interest  in decimal
t is Number of Time Periods  
n is the number of times interest is compounded per year
in this problem we have  
 
  
substitute in the formula above  
 
  
 
        
             
        
        
        
Answer:
B. 1.2 x 
Step-by-step explanation:
Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.  Or, in this case it's the opposite since we have a negative number. Since it's a decimal it's multiplied by 10 still but the exponent is negative. All we need to do to find what the exponent would be in this case is to count the number of zeros before the "12." There are 4 zeros before the 12. So your exponent would be -4. Now all we need to do is write out "equation" per say. 
1.2 x 10^-4
