Answer: 12.5 %
Explanation:
Hi, to answer this question we have to apply the simple interest formula:
I = p x r x t
Where:
I = interest (investment after interests - principal; 12000-8000=4000)
P = Principal Amount (initial invest)
r = Interest Rate (decimal form)
t= time
Replacing with the values given
4,000= 8,000 (x) 4
Solving for x
:
4,000= 32,000x
4,000/ 32,000 =x
x= 0.125
Since the interest rate is in decimal form, we have to multiply it by 100 to obtain the percentage.
0.125 x 100 = 12.5 %

Answer:
b. A performance metric that measures timeliness of the flight, where a flight is considered "on time" as long as the flight is boarded and away from the gate by the scheduled departure time
Explanation:
We are told that airplanes make a mock depart by exiting the boarding gates, but they stay on the runway for long periods of time. This is due to the fact that airlines measure which planes are on time based on the moment that they left the boarding gate, not when they actually lift into the air. it happened to me once and it was extremely unpleasant to just sit without moving for more than one hour. I doubt any passenger likes these type of situations.
