So if you 12 centimeter cubes to build a rectangular prism, the prism has a volume of _______ cubic centimeters, or _______ cm

-Dominant- [34]

1728 cubic centimeters

12 with the exponent of 3 would basically be 12x12x12 but easier i put 12x12=144x12= which is 1728

cuz if its just 12x12 thats just the area of one side, if its 12x12x12 its the volume of the whole cube/rectangular prism

Answer:

The 95 percent confidence interval for the true mean metal thickness is between 0.2903 mm and 0.2907 mm

Step-by-step explanation:

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1-0.95}{2} = 0.025$

Now, we have to find z in the Ztable as such z has a pvalue of $1-\alpha$ .

So it is z with a pvalue of $1-0.025 = 0.975$ , so $z = 1.96$

Now, find the margin of error M as such

$M = z*\frac{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation of the population and n is the size of the sample.

$M = 1.96\frac{0.000586}{\sqrt{59}} = 0.0002$

The lower end of the interval is the sample mean subtracted by M. So it is 0.2905 - 0.0002 = 0.2903 mm

The upper end of the interval is the sample mean added to M. So it is 0.2905 + 0.0002 = 0.2907 mm

The 95 percent confidence interval for the true mean metal thickness is between 0.2903 mm and 0.2907 mm
