Computer geometric modeling is used regularly to help design solid figures we see and use every day. Software programs use techn
Stella [2.4K]

The geometric modeling is analyzed below.

<h3>How to illustrate the information?</h3>

Basic shapes are generally created using points, lines, circles, and triangles. Some basic shapes are rectangles, ellipses, triangles, and curves.

In geometric modeling, we make a cad model of parts for virtual analysis. By geometric modeling, one can model, and perform CAE analysis to optimize the product.

The best part is the period of doing all this is very small compared to practical manufacturing and looking at the product. In CAD one can very quickly alter the design and come up with new concepts in a very small span of time.

Here chances of error can be shorted easily and there is no wastage of material hence cost saving is there compared to practically manufacturing the part and altering it.

What is 5/47 as a decimal rounded to 3 decimal places?
MAXImum [283]

Answer:

You divide 5 by 47 and then see if the fourth digit after the decimal is 5 or greater or less than 5. If it's less, the digit before it remains the same and the decimal cuts off at it. If it's 5 or greater, the digit before it goes up one and the. decimal cuts off at it. Using this, you should get 0.106, I think.

Use the given information to find the minimum sample size required to estimate an unknown population mean μ.
larisa86 [58]

Answer:

The number of business students that must be randomly selected to estimate the mean monthly earnings of business students at one college is 64.

Step-by-step explanation:

The (1 - <em>α</em>) % confidence interval for population mean is:

 CI=\bar x\pm z_{\alpha/2}\ \frac{\sigma}{\sqrt{n}}

The margin of error for this interval is:

 MOE= z_{\alpha/2}\ \frac{\sigma}{\sqrt{n}}

The information provided is:

<em>σ</em> = $569

MOE = $140

Confidence level = 95%

<em>α</em> = 5%

Compute the critical value of <em>z</em> for <em>α</em> = 5% as follows:

 z_{\alpha/2}=z_{0.05/2}=z_{0.025}=1.96

*Use a <em>z</em>-table.

Compute the sample size required as follows:

MOE= z_{\alpha/2}\ \frac{\sigma}{\sqrt{n}}  

       n=[\frac{z_{\alpha/2}\times \sigma}{MOE}]^{2}

          =[\frac{1.96\times 569}{140}]^{2}\\\\=63.457156\\\\\approx 64

Thus, the number of business students that must be randomly selected to estimate the mean monthly earnings of business students at one college is 64.
