Answer: 0.5
Step-by-step explanation:
Given : Adult male heights have a normal probability distribution .
Population mean : 
Standard deviation: 
Let x be the random variable that represent the heights of adult male.
z-score : 
For x=70, we have

Now, by using the standard normal distribution table, we have
The probability that a randomly selected male is more than 70 inches tall :-

Hence, the probability that a randomly selected male is more than 70 inches tall = 0.5
Convert it then you will fine the weight.
If this is multiple choice im gonna say C
Answer:
I think the answer is 21
Step-by-step explanation:
The answer is 21 because we can simple reduce 26/39 = 2/3. And now that you have done that all we need to do is find what 14/w = 2/3 this is quite simple as we just have to mutiply the 3*7 to get 21 as your answer. I don't know if this is correct or not but this is my best answer.
