Answer:
The value of g(f(1)) is 84/5
Step-by-step explanation:
To find the answer to a composite function, start with the function on the inside, which is f(1). So, we input 1 into the f(x) equation and evaluate. 
f(x) = 6x + 2
f(1) = 6(1) + 2
f(1) = 6 + 2
f(1) = 8
Now that we have the answer of 8, we can input that in for x in the outside function, which is g(x). 
g(x) = 2x + 4/5
g(8) = 2(8) + 4/5
g(8) = 16 + 4/5
g(8) = 84/5
 
        
             
        
        
        
Answer:
The required probability is 0.533.
Step-by-step explanation:
Consider the provided information.
The actual weight of the chocolate has a uniform distribution ranging from 31 to 32.5 ounces. 
Let x is the random variable for the actual weight of chocolate. 
According to PDF function.

Where 
It is given that ranging from 31 to 32.5 ounces. 
Substitute a=31 and b=32.5 in above function.


We need to find the probability that a box weighs less than 31.8 ounces
Now according to PDF:


Hence, the required probability is 0.533.
