Answer:
The answer is below
Step-by-step explanation:
Using binomial probability:
p = probability of a rural student getting admission = 1/2
q = probability of a rural student not getting admission = 1/2
n = number of students = 100
P(x) = 
But 
P(x > 50) = P(x = 51) + P(x = 52) + P(x = 53) + . . . + P(x = 100)
P(x > 50) = ![\frac{1}{2} ^{100}[C(100,51)+C(100,52)+C(100,53)+\ .\ .\ .+C(100,100)]\\](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%5E%7B100%7D%5BC%28100%2C51%29%2BC%28100%2C52%29%2BC%28100%2C53%29%2B%5C%20.%5C%20.%5C%20.%2BC%28100%2C100%29%5D%5C%5C)

Answer:
You will use 8 gallons of gas.
Step-by-step explanation:
1/3 +2/3 = 1 whole, so this iis the same as a^1. Answer, a^1/3 x a^2/3 = a
Hi there,
If what you are trying to find is the volume, then:
Here's the equation:
4×6×2 = 48 --- volume of the smaller rectangular box
12×14×2 = 336 --- volume of the bigger box
48 + 336 = 384 --- the total volume of the figure
Hope this helped :P
