N^2 + n - 120 = 0
Quadratic formula
a = 1, b = 1, c = -120
n = [-1 plus or minus root(1^2 - 4(1)(-120))] / 2(1)
n = (-1 plus or minus root481)/2
n =(approximately) 10.5 or -11.5
The answer is 15 foot 7 inches or 187 inches.
The answer is B.
If a coin is flipped 14 times and lands on heads 10 times the fraction would equal to 10/14.
