An aircraft firm is considering three different alloys for use in the wing construction of a new airplane. Each alloy can be produced in four different thicknesses (1 = thinnest, 4 = thickest). Two test samples are constructed for each combination of alloy type and thickness, then each of the 24 test samples is subjected to a laboratory device the severely flexes it until failure occurs. For each test sample the number of flexes before failure is recorded, with the results shown in the Aircraft worksheet in the ANOVA HW data workbook on Moodle.

a) Use JMP to fit a two-way ANOVA to the data. Using alpha = 0.05 draw conclusions for the ANOVA. Make sure you state your conclusion in the context of the problem.

b) Does there appear to be a need to include the alloy type / thickness interaction term?

c) Use JMP to fit a two-way ANOVA with interaction to the data. Using alpha= 0.05 draw conclusions for the ANOVA. Make sure you state your conclusion in the context of the problem.

Below is information on several bonds of different maturities and coupon rates that trade in the same market. If the bonds pay a coupon, you may assume that the coupon is paid semi-annually, with the next coupon payment six months away. All bonds have a face value of $1,000.

For Bonds 1-4, assuming that they are fairly valued, calculate the spot interest rates for maturities of 0.5, 1.0, 1.5 and 2.0 years.

What is the Yield to Maturity (YTM) for each of the four (4) bonds?

Bond 5 trades in this market place. It has a maturity of 1 year, a coupon rate of 3.5% per year (paid semi-annually) and a face value of $1,000. What is the value of the bond?

Reverse Polish notation is a notation where every operator follows all of its operands. For example, an expression (1+2)*(5+4) in the conventional Polish notation can be represented as 1 2 + 5 4 + * in the Reverse Polish notation. One of advantages of the Reverse Polish notation is that it is parenthesis-free.

Write a program which reads an expression in the Reverse Polish notation and prints the computational result.

An expression in the Reverse Polish notation is calculated using a stack. To evaluate the expression, the program should read symbols in order. If the symbol is an operand, the corresponding value should be pushed into the stack. On the other hand, if the symbols is an operator, the program should pop two elements from the stack, perform the corresponding operations, then push the result in to the stack. The program should repeat this operations.

Input

An expression is given in a line. Two consequtive symbols (operand or operator) are separated by a space character.

You can assume that +, - and * are given as the operator and an operand is a positive integer less than 10⁶

Output

Print the computational result in a line.

Constraints

2 ≤ the number of operands in the expression ≤ 100
1 ≤ the number of operators in the expression ≤ 99
-1 × 10⁹ ≤ values in the stack ≤ 10⁹

Sample Input 1

1 2 +

Sample Output 1

Sample Input 2

1 2 + 3 4 - *

Sample Output 2

(Algebra: vertex form equations) The equation of a parabola can be expressed in either standard form (y = ax^2 + bx + c) or vertex form (y = a(x-h)^2 + k). Write a program that prompts the user to enter a, b, and c as integers in standard form and displays h and k in the vertex form. Hint: Use the Rational class in LiveExample 13.13 for computing h and k. Use the template at https://liveexample.pearsoncmg.com/test/Exercise13_21Test.txt for your code. Sample Run 1 Enter a, b, c: 1 3 1 h is -3/2 k is -5/4 Sample Run 2 Enter a, b, c: 2 3 4 h is -3/4 k is 23/8 Class Name: Exercise13_21 If you get a logical or runtime error, please refer https://liveexample.pearsoncmg.com/faq.html.
