What is the sum of the geometric series

lbvjy [14]

If $S$ denotes the sum of the first $n$ terms of a geometric series with first term $a$ and common ratio $r$ , then

$S=a+ar+ar^2+\cdots+ar^{n-3}+ar^{n-2}+ar^{n-1}$
$rS=ar+ar^2+ar^3+\cdots+ar^{n-2}+ar^{n-1}+ar^n$
$\implies S-rS=a+(ar-ar)+(ar^2-ar^2)+\cdots+(ar^{n-1}-ar^{n-1})-ar^n$
$\implies (1-r)S=a(1-r^n)$
$\implies S=a=\dfrac{1-r^n}{1-r}$

Using summation notation, you have

$S=\displaystyle\sum_{x=1}^nar^{x-1}=\sum_{x=0}^{n-1}ar^x=a\dfrac{1-r^n}{1-r}$

In this case, you have $a=2$ , $r=\dfrac12$ , and $n=16$ . So the value of the sum is

$\displaystyle\sum_{x=0}^{15}2\left(\frac14\right)^x=2\dfrac{1-\left(\frac14\right)^{16}}{1-\frac14}\approx2.67$

Rounded to the nearest whole number, the answer would be 3.

Out of 4,000 colleges surveyed, 60% reported that SAT scores were not used as a high consideration in viewing their applications

Oduvanchick [21]

Answer:

Hi.

The first thing you want to know is how many schools 60% is.

To find 60%: 4,000 x 0.6 (b/c 0.6 = 60%)

so, 60% of 4,000 = 2,400

To find the number of schools that consider SAT scores:

Subtract 2,400 from 4,000 which, equals 1,600

Find the remaining percentage; 40%:

4,000 x 0.4 = 1,600

Answer: 1,600 colleges

I hope this helps a little bit.
