Answer:
and we can find this probability using the complement rule and we got:
So then we can conclude that approximately 8.38% of the men are taller than women
Step-by-step explanation:
Let X the random variable who represent the heights of women aged 20 to 29 and the distribution is given by:
And let Y the heights of men aged 20 to 29 and the distribution for Y is given by:
And for this case we want to find the following probability:
The distribution for Y-X is given by:
We can define the random variable Z= Y-X and the we can use the z score formula given by:
And using the z score formula we got:
and we can find this probability using the complement rule and we got:
So then we can conclude that approximately 8.38% of the men are taller than women
Answer:
cos x (2 sin x − 1)
Step-by-step explanation:
sin(2x) − cos x
Use double angle formula.
2 sin x cos x − cos x
Factor.
cos x (2 sin x − 1)
