Answer:
The probability that an 18-year-old man selected at random is greater than 65 inches tall is 0.8413.
Step-by-step explanation:
We are given that the heights of 18-year-old men are approximately normally distributed with mean 68 inches and a standard deviation of 3 inches.
Let X = <u><em>heights of 18-year-old men.</em></u>
So, X ~ Normal( )
)
The z-score probability distribution for the normal distribution is given by;
                               Z  =   ~ N(0,1)
  ~ N(0,1)
where,  = mean height = 68 inches
 = mean height = 68 inches
             = standard deviation = 3 inches
 = standard deviation = 3 inches
Now, the probability that an 18-year-old man selected at random is greater than 65 inches tall is given by = P(X > 65 inches) 
        P(X > 65 inches) = P(  >
 >  ) = P(Z > -1) = P(Z < 1)
 ) = P(Z > -1) = P(Z < 1) 
                                                                 = <u>0.8413</u>
The above probability is calculated by looking at the value of x = 1 in the z table which has an area of 0.8413.
 
        
             
        
        
        
Answer:   24
Step-by-step explanation:
Follow PEMDAS. Parentheses: 16+a, which is 18. There are no exponents so move on to multiplication. 6b. B is equal to 3, and 6x3 is 18. Next, division. 18/3 is 6. Now do addition so add together 18+6 which is 24.
 
        
             
        
        
        
64 as it’s multiplied by 2 each time
