Answer: An inequality is a mathematical or arithmetic phrase that is not equal; this inequality prohibits the equal sign. Instead, inequalities are expressed with greater than (>), less than (<), equal to or greater than (≥) or equal to or less than (≤).
 
        
                    
             
        
        
        
Answer:
The probability that the proportion of passed keypads is between 0.72 and 0.80 is 0.6677.
Step-by-step explanation:
According to the Central limit theorem, if from an unknown population large samples of sizes <em>n</em> > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
  
The standard deviation of this sampling distribution of sample proportion is:

Let <em>p</em> = the proportion of keypads that pass inspection at a cell phone assembly plant.
The probability that a randomly selected cell phone keypad passes the inspection is, <em>p</em> = 0.77.
A random sample of <em>n</em> = 111 keypads is analyzed.
Then the sampling distribution of  is:
 is:

Compute the probability that the proportion of passed keypads is between 0.72 and 0.80 as follows:

                              
Thus, the probability that the proportion of passed keypads is between 0.72 and 0.80 is 0.6677.

Answer:
the answer is G(x)=x^2 + 1
- if you add +1, the y value will increase 1 point upward making the other function equal to g(x)=x^2 + 1. the difference between the two functions is the + 1.
