Answer:
x = 39
Step-by-step explanation:
there is a theorem that states that the midsegment in a trapezoid is equal to the sum of the bases divided by two
so, (36 + 42)/2 = x
36 + 42 = 78
78/2 = 39
Exponential laws
![x^{\frac{m}{n}}=\sqrt[n]{x^{m}}](https://tex.z-dn.net/?f=%20x%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D%3D%5Csqrt%5Bn%5D%7Bx%5E%7Bm%7D%7D%20)
so
(m^(2/3))^(1/2)=m^(2/3 times 1/2)=m^(2/6)=m^(1/3)=
![\sqrt[3]{m^{1}}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7Bm%5E%7B1%7D%7D%20)
=
![\sqrt[3]{m}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7Bm%7D%20)
The two events are independent of each other.
According to the question during a game of roulette, a wheel is spun and a ball drops randomly into one of the wheel's numbered compartments. The ball can drop in any one of the wheel's numbered compartments , there is no restriction on it.
Now, the process is repeated with another random spin. when the process is repeated the ball can drop in any one of the wheel's numbered compartments , there is no restriction on it. As the first spin does not affect the second spin, we can conclude that these two events are completely independent of each other.
