Answer:
i'll answer the question after you clarify for me, if f(x) =-2x +3
then f (this is what you need to clarify for me please, theres 2 end parenthesis, but no start parenthesis and 2 numbers and 2 equal signs. what needs solved?)
Step-by-step explanation:
Answer: 1.467
Step-by-step explanation:
Formula of Margin of Error for (n<30):-
![E=t_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}](https://tex.z-dn.net/?f=E%3Dt_%7B%5Calpha%2F2%7D%5Cdfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D)
Given : Sample size : n= 22
Level of confidence = 0.90
Significance level : ![\alpha=1-0.90=0.10](https://tex.z-dn.net/?f=%5Calpha%3D1-0.90%3D0.10)
By using the t-distribution table ,
Critical value : ![t_{n-1, \alpha/2}=t_{21,0.05}= 1.720743](https://tex.z-dn.net/?f=t_%7Bn-1%2C%20%5Calpha%2F2%7D%3Dt_%7B21%2C0.05%7D%3D%201.720743)
Standard deviation: ![\sigma=4](https://tex.z-dn.net/?f=%5Csigma%3D4)
Then, we have
![E=(1.720743)\dfrac{4}{\sqrt{22}}=1.46745456106\approx1.467](https://tex.z-dn.net/?f=E%3D%281.720743%29%5Cdfrac%7B4%7D%7B%5Csqrt%7B22%7D%7D%3D1.46745456106%5Capprox1.467)
Hence, the margin of error for the confidence interval for the population mean with a 90% confidence level =1.467
I do questions like these a little different than most people so...
384/12= 32 (32 is 1% of his sales)
32*100= 3200
His total sales were $3200.
Can you specify the question please I can answer it but I need more specification 87

</h3><h3>
</h3><h3>1.) <u>Graph:</u></h3>
- Since we know
, you graph
on the
-axis. And this is an ending, meaning it doesn't go on forever.
- However, we don't know what
is. So because we don't know what
is we still graph it but it'll go on forever.
<em> - You can either graph this like this, OR graph this using desmos.com. </em>
<h3><u /></h3><h3><u>Vertical or Horizontal?</u> </h3>
Horizontal, Left and Right.
- <em />
<em> </em>Vertical, Up and Down.
- So since we know
is, (Horizontal,) we have to graph
, (Vertical.) So to sum this up, this just means whatever variable you don't know yet, that will be the one that you graph as an infinite.
