Presuming the question is "How many points did he miss", you would find the solution by multiplying the amount of possible points by the test score as a fraction. 96% is the fraction

. Therefore, you get the equation

. This is equal to 72, so he missed 3 points, or 75-72 points.
He missed 3 points.
For this case, the first thing we must do is define variables:
p: plane speed
w: wind speed
With the wind in favor, the speed is:

With the wind against the speed is:

Rewriting both equations, we have the following system of equations:

Then, solving the system of equations (graphically for example), we have the solution is:

Therefore, jet stream's speed:
Answer:
A) p + w = 960; p - w = 600; jet stream's speed = 180 km / h
This is called the median.
Answer:
3/6 converted to a decimal would be 0.5
Step-by-step explanation:
Hope this helps. :)
