To do this, we first want to see how many participants there are in total by adding both males and females.

Now we know that there were 220 total participants, but only 121 were females.
This allows us to set up the fraction 121/220= the percent female.

or 55%
Answer:
2 2/5

Hello from MrBillDoesMath!
Answer:
The fourth choice, b = +\- sqrt( sg + a^2)
Discussion:
s = (b^2 - a^2)/g => multiply both sides by "g"
sg = b^2 - a^2 => add a^2 to both sides
sg + a^2 = b^2 => take the square root of each side
b = +\- sqrt( sg + a^2)
which is the fourth choice.
Thank you,

F(x) = 2x - 1
subtitute x = 0 to the equation:
f(0) = 2· 0 -1 = 0 - 1 = -1
f(0) = -1

Step-by-step explanation:
-x, -(x+1)
-x-(x+1)=10506
x^2+x-10506=0
