The equation given in the question is
- 14 = 2/3t
Then
- 14 * 3t = 2
- 42t = 2
-t = 2/42
= 1/21
Now multiplying both sides with - 1 we get
t = 1/21
The value of t comes out to be equal to - 1/21.

Answer: The percent higher is 41.68%. If 49 planes were selected, 20 of them should be above 15 years.
To find the percent, we first need the z-score.
(15 - 13.5) / 7.3 = 0.21
Now, use a normal distribution table to find the percent above a score of 0.21. It will be 41.68%.
To find the number of 49 planes above this value, multiply 49 by 0.4168. You will have about 20.4 planes.
1+(1*4)=5
2+(2*5)=12
3+(3*6)=21
5+(5*8)=45
