Answer:  100+1.28(1/2)=100.64 
Step-by-step explanation:
A random sample of size 16 is to be taken from a normal population having mean 100 and variance 4. ... The 90th percentile of the normal curve, according to the table I was provided, was equal to 1.28 standard units above the mean.
 
        
             
        
        
        
10 pancakes produces 8 inches in diameter. 
The area of 1 pancake is 
Area = pi * r^2
Area = pi * 4^2
Area = 50.27 in^2
Then multiply it by 10
Total area = 502.65 in^2
A smaller pancake
Area = pi * r^2
Area = pi * 2^2
<span>Area = 12.56 in^2
Divide 502.65 by 12.56
= 502.65 / 12.65
= 39.74
So there are 39 pancakes.

I believe yes
Each time it goes up by one, it is always increasing by the same amount each time
 
        
                    
             
        
        
        
B because both lines a and b are parallel which makes 1 and 9 congruent
