The next time you make a trip to a supermarket, ask the manager if you can measure the mass of at least 10 cereal boxes of your choice. Choose the same brand and the same size boxes. Tell the manager this is an assignment for a class. Report the average mass, variance, and standard deviation for the cereal boxes. Does the manufacturer’s information noted on the box fall within your measurement?

An engineering professor acquires a new computer once every two years. The professor can choose from three models: M1, M2, and M3. If the present model is M1, the next computer can be M2 with probability 0.25 or M3 with probability 0.1. If the present model is M2, the probabilities of switching to M1 and M3 are 0.5 and 0.15, respectively. And, if the present model is M3, then the probabilities of purchasing M1 and M2 are 0.7 and 0.2, respectively. Represent the situation as a Markov chain and express the probabilistic activities in the form of transition matrix. Analyzing the problem in (c), Write the steady-state equations

Hi! The previous tutor answered this question already. I am just confused about the number of days in a year. The tutor uses 365 days, isn't 360 days? Since the question doesn't state any exact value, but only it assumes so I think it is 360 days, right? If the tutor's answer is correct, please enlighten and describe further why is it 365 days and not 360 days. This is the question: Find the present value on Oct. 9, 2020, if the amount on February 4, 2021, is Php. 4,600 with a discount rate of 3 4/5 %

The Body Mass Index (BMI) is a way of determining obesity and whether someone is overweight. It is computed from BMI=mass(inkg)[height(inmeter)]2. Write a program that will create the table shown in accompanying figure. The BMI values in the range of 18.524.9, 25.029.9, and 300. are considered healthy, overweight, and obese, respectively.
