A ship is traveling due north. Every 30 mins,the captain corrects his course by a certain number of degrees.Here are the corrections made during the first four hours of the voyage: 5,-7,3,2,-6,8,-4,-6 ps theres degrees in the numbers

Note:in marine Navigation the course is the ships direction and the degrees Are the units used to indicate the ships direction relative to north. If the change in direction is to the left the number of degrees is positive if it is toward the right the number of degrees is negative

To determine the final course of the ship after the given corrections, you need to add up all the degrees of correction in a systematic manner.

Let's calculate the final course of the ship after the corrections:

Start with the initial course of the ship, which is due north: 0 degrees.

After 30 minutes:
- Add the first correction of 5 degrees to the initial course: 0 + 5 = 5 degrees.

After 1 hour:
- Add the second correction of -7 degrees to the previous course: 5 - 7 = -2 degrees.

After 1.5 hours:
- Add the third correction of 3 degrees to the previous course: -2 + 3 = 1 degree.

After 2 hours:
- Add the fourth correction of 2 degrees to the previous course: 1 + 2 = 3 degrees.

After 2.5 hours:
- Add the fifth correction of -6 degrees to the previous course: 3 - 6 = -3 degrees.

After 3 hours:
- Add the sixth correction of 8 degrees to the previous course: -3 + 8 = 5 degrees.

After 3.5 hours:
- Add the seventh correction of -4 degrees to the previous course: 5 - 4 = 1 degree.

After 4 hours:
- Add the eighth correction of -6 degrees to the previous course: 1 - 6 = -5 degrees.

Therefore, the final course of the ship after the given corrections is -5 degrees, which means it is pointing towards 5 degrees to the left of due north.
