14, finding the rate of change is simple,
142-128 = 14
156-142 = 14
170-156 = 14
184-170 = 14
14+14+14+14 = 56
There are 4 integers so divide by 4
56/4 = 14
so the answer is 14

Step-by-step explanation:
There are six digits to choose from, but you're only taking three at a time, so the number of such numbers is
![{}_6P_3=\dfrac{6!}{3!}=6\times5\times4=120](https://tex.z-dn.net/?f=%7B%7D_6P_3%3D%5Cdfrac%7B6%21%7D%7B3%21%7D%3D6%5Ctimes5%5Ctimes4%3D120)
The first and last digits can only be even if the number takes the one of the forms "2 _ 8" or "8 _ 2". The middle number can be any of the remaining four, so there is a total of eight such numbers.
This means the probability of getting a number beginning and ending with an even digits is
![\dfrac8{120}=\dfrac1{15}](https://tex.z-dn.net/?f=%5Cdfrac8%7B120%7D%3D%5Cdfrac1%7B15%7D)
.
Height equals 80 meters times sin(angle of 75 degrees)
h = 80 (0.966) = 77.27 meters height of kite from the ground
