Here's the solution and answers to the ME board questions in Mathematics (Statistics and Probability) 1. In how many ways can you arrange a group of 5 girls and 3 boys in 7 vacant chairs? Solution: The total number of persons to be seated is 8 and the number of chairs is only 7. When words denoting “arrangement” are used, it most likely pertains to permutations. So, the formula to be used is permutation of 8 taking 7 at a time. n = 8, r = 7, nPr, then use your calculator or this formula nPr = n!/(n-r)! = 8!(8-1)!=40320 permutations or arrangements A. 40320 2. How many 3-digit numbers can you make out of the numbers 1 to 5 without repetition? Solution: Since the number varies as you rearrange the digits (example 1342 is different from 1423), then this problem is about permutation. So, the formula is the permutation of 5 numbers taken 3 at a time. n = 5, r = 3, nPr; use your calculator or this formula: nPr = n!/(n-r)! nPr = 5!/(5-3)!=60 permutations C. 60 3. There

1. Which of the following is the solution set of the equation x2-2x-15 = 0 Solution : Think of factors of the last digit that when subtracted gives the coefficient of the middle term In this case, -15 can only be (3, -5), (-3, 5), (15, -1) or (-15, 1). Among these factors, (3, -5) is the only one whose sum will be equal to -3. So the solution set of the equation will be X-5=0; x1 = 5 X+3=0; x2 = -3 Alternative Solution: By trial and error (best when using your calculator), try each choices and see which among them when substituted to x will make the equation true, that is, x2-2x-15 equals zero. B. (5, -3) 2. The next term in the progression 2, 8, 32, 128 is … Solution : The progression above is a Geometric progression since there is a common ratio (r). In this case, the common ratio is 4 and the next terms are obtained by multiplying the previous term by 4. So, next to 128 will be 128X 4 = 512 C. 512 3. Solve for x in the equation 3 lnx = 8 Solution : Using prope

Dear valued readers, When I started Mechanical Engineering Blog Site about a year ago, my sole purpose is to provide a way for me to share my ideas as a mechanical engineer to the world especially to students and fellow professionals. But as time goes by, Mechanical Engineering Blog Site has grown from being a simple personal blog, to a website that provides free online review materials for those who will be taking the board exam on mechanical engineering. With that growth, I decided to have my own domain name. Hence, last June 2010, from just being a free Blogspot subdomain (www.tupmechanical.blogspot.com) it became a www.tupmechanical.com. Along with this change is the creation of my own email address, admin@tupmechanical.com where you can directly email your concerns and questions to me. The growth though, does not stop on domain name change. Today, I am formally introducing two (2) new features on this site. One is the CHAT WIDGET , powered by ShoutJax and the other one is

The Professional Regulations Commission has yet to announce the results of this year's second phase board exam for Registered Mechanical Engineers (RME), Professional Mechanical Engineers (PME), and Certified Plant Mechanic (CPM). Upon its release, it will be immediately posted in this blog, so please stay tune. Based on previous exams, the results can come out as quick as one day of processing so it can be sometime tonight or tomorrow. Meanwhile, try to sit down and relax. I am very much aware that the waiting period can be really hard. When I took the board three years ago, I had two days of intermittent sleep because of   worries about the result. But after the results came out, the excitement, the thrill, the nervousness, and the anxieties started to wane. Image via Wikipedia For those who will pass, please accept my warmest congratulations. For those who will not (of course, we all know that there's no 100% passing rate), accept the current situation but don't tr
