Chapter 3, Problem 16P

The area of a triangle ABC can be calculated by r A B × r A C / 2 , where rABand rACare vectors connecting the vertices A and B, and A and C, respectively. Determine the area of the triangle shown in the figure. Use the following steps in a script tile to calculate the area.

First, define the vectors rOA, rOB, and rOCfrom knowing the coordinates of points A, B, and C. Then determine the vectors rABand rACfrom rOA, rOBand rOC. Finally, determine the area by using MATLAB’s built-in functions cross, sum, and sqrt.

4.96 The  breaking  strengths  for  1-foot-square  samples  of  a  particular  synthetic  fabric  are  approximately  normally  distributed  with  a  mean  of  2,250  pounds  per  square  inch  (psi)  and  a  standard deviation of 10.2 psi. Find the probability of selecting a  1-foot-square sample of material at random that on testing would have a breaking strength in excess of 2,265 psi.4.97 Refer to Exercise 4.96. Suppose that a new synthetic fabric has been developed that may have a different mean breaking strength. A random sample of 15  1-foot sections is obtained, and each section is tested for breaking strength. If we assume that the population standard deviation for the new fabric is identical to that for the old fabric, describe the sampling distribution forybased on random samples of 15  1-foot sections of new fabric
