Answer:
true
Step-by-step explanation:
well youll have to multiply both sides by v to get m alone. and youre left with DxV=M

Answer:
9
Step-by-step explanation:
18 times 1
then divided by 2
is 9
Answer: 2.460
Step-by-step explanation:
The formula of Margin of Error for (n<30):-
![ME=t_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}](https://tex.z-dn.net/?f=ME%3Dt_%7B%5Calpha%2F2%7D%5Cdfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D)
Given : Sample size : n= 18
Level of confidence = 0.90
Significance level : ![\alpha=1-0.90=0.1](https://tex.z-dn.net/?f=%5Calpha%3D1-0.90%3D0.1)
Using the t-distribution table ,
Critical value : ![t_{n-1, \alpha/2}=t_{17,0.05}= 1.7396](https://tex.z-dn.net/?f=t_%7Bn-1%2C%20%5Calpha%2F2%7D%3Dt_%7B17%2C0.05%7D%3D%201.7396)
Standard deviation: ![\sigma=\text{ 6 inches }](https://tex.z-dn.net/?f=%5Csigma%3D%5Ctext%7B%206%20inches%20%7D)
Then, we have
![ME=( 1.7396)\dfrac{6}{\sqrt{18}}\approx2.460](https://tex.z-dn.net/?f=ME%3D%28%201.7396%29%5Cdfrac%7B6%7D%7B%5Csqrt%7B18%7D%7D%5Capprox2.460)
Hence, the margin of error (ME) of the confidence interval with a 90% confidence level = 2.460

The edited video would now be 5 Minutes 50 Seconds
Step-by-step explanation:
10-4.5=5.5
To subtract any percentage from a number, simply multiply that number by the percentage you want to remain. In other words, multiply by 100 percent minus the percentage you want to subtract, in decimal form. To subtract 20 percent, multiply by 80 percent (0.8).
