Answer:
a. N(500, 100)
Step-by-step explanation:
The normal probability distribution, with mean M and standard deviation S, can be represented in the following notation.
N(M,S).
In this problem, we have that:
Mean = 500
Standard deviation = 100
Which of the following options would be the correct way to represent the information?
a. N(500, 100)
 
        
             
        
        
        
Answer:
2π/7
Step-by-step explanation:
A cosine wave is:
y = A cos(2π/T x + B) + C
where A is the amplitude,
T is the period,
B is the horizontal shift,
and C is the vertical shift.
In this case:
7 = 2π/T
T = 2π/7
 
        
                    
             
        
        
        
Hi,
Solution:
Find Common Denominators,
2/5 = 8/20
2 7/20
Turn into improper fractions,
2 7/10 = 47/20
Divide,
47/20 ÷ 8/20 = 5.875/1 = 5 7/8
Answer,
5 7/8
