Answer: 1537.

Step-by-step explanation:

Formula for sample size :-

$n=(\dfrac{z_{\alpha/2}\cdot \sigma}{E})^2$

Given : $\sigma=2000$

Margin of error : E= 100

Critical value of 95% confidence : $z_{\alpha/2}=1.96$

Now, the required sample size will be :-

$n=(\dfrac{1.96\cdot 2000}{100})^2\\\\=1536.64\approx1537$

Hence, the minimum sample size required = 1537.

What is the sum of the geometric sequence 4, 16, 64, ... if there are 8 terms? (6 points)

PtichkaEL [24]

Answer:

87380

Step-by-step explanation:

The sum to n terms of a geometric sequence is

$S_{n}$ = $\frac{a(r^n-1)}{r-1}$

where a is the first term and r the common ratio

r = $\frac{16}{4}$ = 4 and a = 4, hence

$S_{8}$ = $\frac{4(4^8-1)}{4-1}$ = $\frac{4(65535)}{4}$ = 87380

Answer:

The population in year 2014 is 41100.

Step-by-step explanation:

In the question, it is given that the city's population is growing linearly. In 2008 , population was 28200 and in 2012 , it is 36800 .

It is required to predict the population in 2014 .

To do so, use the population given in two years as two points on a line and find the equation of population and year. Then, find the population in year 2014 .

Step 1 of 2

The population in 2008 was 28200 and in 2012 it was, 36800 .

The equation relating population and year is,

$\begin{aligned}&y-28200=\left(\frac{36800-28200}{2012-2008}\right)(x-2008) \\&y-28200=\left(\frac{8600}{4}\right)(x-2008) \\&y-28200=2150(x-2008)\end{aligned}$

Step 2 of 2

The population in year 2014 can be determined by substituting 2014 for x,

$\begin{aligned}&y-28200=2150(2014-2008) \\&y-28200=2150(6) \\&y-28200=12900 \\&y=41100\end{aligned}$
