Answer:
1023
Step-by-step explanation:
![S_n = \dfrac{a(1 - r^n)}{1 - r}](https://tex.z-dn.net/?f=%20S_n%20%3D%20%5Cdfrac%7Ba%281%20-%20r%5En%29%7D%7B1%20-%20r%7D%20)
a = first term
r = common ratio
n = number of terms
Here we have
a = 1
r = 2
n = 10
![S_{10} = \dfrac{1(1 - 2^{10})}{1 - 2}](https://tex.z-dn.net/?f=%20S_%7B10%7D%20%3D%20%5Cdfrac%7B1%281%20-%202%5E%7B10%7D%29%7D%7B1%20-%202%7D%20)
![S_{10} = \dfrac{1 - 1024}{-1}](https://tex.z-dn.net/?f=%20S_%7B10%7D%20%3D%20%5Cdfrac%7B1%20-%201024%7D%7B-1%7D%20)
![S_{10} = \dfrac{-1023}{-1}](https://tex.z-dn.net/?f=%20S_%7B10%7D%20%3D%20%5Cdfrac%7B-1023%7D%7B-1%7D%20)
![S_{10} = 1023](https://tex.z-dn.net/?f=%20S_%7B10%7D%20%3D%201023%20)
Of course, since 10 is not such a large number of terms, you can simply do this:
1 + 2 + 4 + 8 + 16 + 32 + 64 + 128 + 256 + 512 = 1023
Answer is
The vertex of the function is (-2, -2)

Find the number of girls by subtracting number of boys from total:
726 - 340 = 386 girls
Divide number of girls by total students:
386/726 = 0.53168
Multiply by 100 get get percent:
0.53168 x 100 = 53.168%
Round to the nearest whole percent: 53% are girls
