Answer: The speed is 22.2 mi/hr and woman is 8° north relative to the surface of the water.
Step-by-step explanation:
Since we have given that
Speed at which woman walks due west = 3 mi/hr
Speed at which ship moving due north = 22 mi/hr
Now it forms "Pythagorus theorem":
So, it becomes,

And the direction of the woman relative to the surface of the water is given by

Hence, the speed is 22.2 mi/hr and woman is 8° north relative to the surface of the water.
Answer:
4/7x - 5 ________________________________________
Since your second pick is affected by your first pick & your third pick is affected by the first two, it is dependent.
First pick: 18 marbles, 3 are red, so odds are 3/18 = 1/6
Second pick: 17 marbles, 8 are blue, odds are 8/17
Third pick: 16 marbles, 7 are black, odds are 7/16
<span>1/6 * 8/17 * 7/16 = 56/1632 = 7/204 & as mentioned before it's dependent</span>
