The formula for any geometric sequence is an = a1 · rn - 1, where an represents the value of the nth term, a1 represents the val

kati45 [8]

Answer:

$\huge\boxed{a_n=1\cdot(-2)^{n-1}}$

Step-by-step explanation:

$a_n=a_1r^{n-1}$

We have the geometric sequence: 1, -2, 4, -8, ...

Find the common ratio:

$r=\dfrac{a_2}{a_1}=\dfrac{a_3}{a_2}=...=\dfrac{a_n}{a_{n-1}}$

$a_1=1,\ a_2=-2$

substitute:

$r=\dfrac{-2}{1}=-2$

Substitute

$a_1=1;\ r=-1$

$a_n=a_1r^{n-1}$

$a_n=1\cdot(-2)^{n-1}$

How do you graph x-y=1 and 3x+2y=-12

Nataliya [291]

Answer:

Graph the equations

Step-by-step explanation:

x - y = 1

3x + 2y = - 12

Rewrite equations into y=mx+b form:

y = -1 + x

y = -6 - 1.5x

How do I make this bell curve

Zanzabum

The mean you found is correct, but the standard deviation is not. Recall that the standard deviation $\sigma_s$ ( $s$ for sample) of $n$ points is given by

$\sigma_s=\sqrt{\dfrac1{n-1}\displaystyle\sum_{1\le i\le n}(x_i-\bar x)^2}$

where $n=10$ is the sample size, $\bar x=3740$ is the sample mean, and $x_i$ are the prices listed in the circled column. So

$\sigma_s=\sqrt{\dfrac{(3640-3740)^2+(7595-3740)^2+\cdots+(3390-3740)^2}{10-1}}$

$\implies\sigma_s\approx1443.98\approx1444$

I can't tell if you need to provide any more info beyond this, but given there's a plot of a generalized bell curve, I think you're also supposed to label the plot.

At the center of the bell-shaped/normal distribution is the mean. Notice there are three tick marks to either side of the mean - these are probably supposed to represent prices that fall exactly 1, 2, and 3 standard deviations from the mean. These are, from left to right,

$\bar x-3\sigma_s\approx3740-3(1444)=-592$
