Answer:
And we can find this probability using the complement rule and the normal standard table:
And the best solution would be:
c. 0.3085
Step-by-step explanation:
For this case we can convert all the values to inches in order to standardize the solution:


Let X the random variable that represent the heights of US mens, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
We can use the z score formula given by:
Using this formula we got:
And we can find this probability using the complement rule and the normal standard table:
And the best solution would be:
c. 0.3085
Answer:
John = 41 years
Sam = 32 years
Step-by-step explanation:
2b+h = 4.82
b+2h = 3.70
multiply the second equation by 2:
2b + 4h = 7.40
subtract the first equation from it:
3h = 2.58
h = 0.86
Answer:
(-5,8)
