probability they are all males is 0.041

<u>Step-by-step explanation:</u>

Here we have , 55% of college freshmen are women. If you pick 4 freshmen at random . We need to find What's the probability they are all males . Let's find out:

Probability to have women is 55 % i.e. 0.55 so for men is :

⇒ 1-0.55

⇒ 0.45

Now , 4 persons are randomly chosen and we need to find probability to have all 4 males that will be :

⇒ 0.45(0.45)(0.45)(0.45)

⇒ 0.45^4

⇒ 0.041

Therefore ,  probability they are all males is 0.041

The depth of the water at the end of a pier changes periodically along with the movement of tides. On a particular day, low tide
Valentin [98]
Draw a diagram to illustrate the problem as shown in the figure below.

The minimum depth of 2.5 m occurs at 12:00 am and at 12:30 pm.
Therefore the period i0s T= 12.5 hours.
The maximum depth of 5.5 m occurs at 6:15 am and at 6:45 pm. Therefore the period of T = 12.5 hours is confirmed.

The double amplitude is 5.5 - 2.5 = 3 m, therefore the amplitude is a = 1.5 m.
The mean depth is k = (2.5 + 5.5)/2 = 4.0 m

The model for tide depth is
d=-1.5cos( \frac{2 \pi t}{12.5})+4

That is,
d = -1.5 cos(0.5027t) + 4
where 
d = depth, m
t = time, hours

A plot of the function confirms that the model is correct.
