A third-point bending test was performed on a 2 x 8 wood lumber according to ASTMD198 procedure
with a span of 8ft and the 8in. side is positioned vertically. If the maximum load on both loading bearings was 7,930 lb, calculate the modulus of rupture.
The blood groups of 200 people are distributed as follows: 40 have type A blood, 75 have type B blood, 60 have type O blood, and 25 have type AB blood. If a person from any of the group is selected at random, what is the probability that this person has an O blood type? How about the AB blood type?

a) f(x) = x−2
b) f(x) = x2 −1
c) f(x) = x3
13.2 grams of NaC2H3O2 are added to 1.00 L of a .100 M solution of acetic acid to form an acid buffer. Ka for acetic acid is 1.8e-5. What is the pH of the solution?
.Write a class called LoanProcess with Loan_ No, Customer Name, LoanAmount, EMI_ Amount, Account_Balance as its members. Create a method calculate_EMI() for the LoanAmount, with the rate of interest as 13% for a total of 3 years and store it in the EMI_ Amount. The rest of the information to be passed through constructors. Write another function CheckBalance() which checks if the Account Balance is less than the EMI_AMount. If yes then throw a custom exception. Display "Not Sufficient Balance to repay Loan" in the finally. Give explanatory comments.

Write a statement that assigns numCoins with numNickels + numDimes. Ex: 5 nickels and 6 dimes results in 11 coins.
According to Chemical Engineering Progress (Nov. 1990), approximately 30% of all pipework failures in chemical plants are caused by operator error.
(a) What is the probability that out of the next 20 pipework failures at least 10 are due to operator error?
(b) What is the probability that no more than 4 out of 20 such failures are due to operator error?
(c) Suppose, for a particular plant, that, out of the random sample of 20 such failures, exactly 5 are operational errors.
Do you feel that the 30% figure stated above applies to this plant? Comment.
