Answer:

Step-by-step explanation:
The function that could model this periodic phenomenon will be of the form 

The tide varies between 3ft and 9ft, which means its amplitude  is
 is 

and its midline  is
 is 
 .
.
Furthermore, since at  the tide is at its lowest ( 3 feet ), we know that the trigonometric function we must use is
 the tide is at its lowest ( 3 feet ), we know that the trigonometric function we must use is  .
. 
The period of the full cycle is 14 hours, which means 


giving us

With all of the values of the variables in place, the function modeling the situation now becomes

Answer:
B. 2/3
Step-by-step explanation:
To solve this we have to take into account this axioms:
- The total probability is always equal to 1.
- The probability of a randomly selected point being inside the circle is equal to one minus the probability of being outside the circle.
Then, if the probabilities are proportional to the area, we have 1/3 probability of selecting a point inside a circle and (1-1/3)=2/3 probability of selecting a point that is outside the circle.
Then, the probabilty that a random selected point inside the square (the total probability space) and outside the circle is 2/3.
