We wish to model the blood type of a person. It is known that blood type is
inherited. If both parents carry genes for the AS and AS blood types, each
child has probability 0.3 of getting two S genes and so of having blood type
SS. Different children inherit independently of each other.
a) Write a Matlab program to determine the probability that the first child
these parents have with type SS blood is their fifth child (CR;9)
b) In relation to the three classifications of mathematical models, discuss the
given genetic modelling problem in 2(a)

Question 1

A piezoelectric accelerometer has a damping ratio of 0.65, a proof mass of 0.5 grams, and a spring rate of 10,000 N/mm. What is the damped natural frequency in hz of this device? (Type in an integer)


Hint: Make sure your units of measure are consistent first, then use the formulae to calculate the natural and damped natural frequencies.




Banking, in its crude form, is an age-old phenomenon. It was in existence even in ancient times. In India, the references to money-lending business are found in the Manu Smriti also. But, in India, modern banking started when the English agency houses in Calcutta and Mumbai began to serve as bankers to the East India Company and the Hindustan Bank was the first banking institution of its kind to be established in 1779. Now days, a bank's business is, in a very special sense, a balancing of assets and liabilities. Loans are the children of deposits and deposits are the children loans. Comment
