A company is considering two mutually exclusive projects, the company’s required return is 8 percent and they do not have any capital constraints. Based on the profitability index, what is your recommendation concerning these projects?
Project A Project B
Year Cash Flow Year Cash Flow
0 -$38,500 0 -$42,000
1 $20,000 1 $10,000
2 $24,000 2 $40,000

Two converging lenses, with focal lengths f1 = 8 cm and f2 = 15 cm are separated by 30 cm. The lens on the left has a shorter focal length. An object, 1.5 cm tall, is placed 12 cm to the left of the combination. (i) Determine the position of the final image relative to the lens on the right. (ii) Determine the overall magnification and the height of the final image. (iii) Is the final image real or virtual? Give a reason for your answer. (iv) Is the final image upright or inverted concerning the original object? Give a reason for your answer.

A firm has a WACC of 8% and is deciding between two mutually exclusive projects. Project A has an initial investment of $63. The additional cash flows for project A are: year 1 = $20, year 2 = $39, year 3 = $67. Project B has an initial investment of $73.The cash flows for project B are: year 1 = $60, year 2 = $45, year 3 = $32.

Consider some 8-sided dice. Roll two of these dice. Let X be the minimum of the two values that appear. Let Y denote the maximum.
a) Find the joint mass p_X,Y (x,y).
b) Compute p_X│Y (x│y) in all cases. Express your final answer in terms of a table.

Two sections of a pressure vessel are to be held together by 5/8 in-11 UNC grade 5 bolts. You are told that the length of the bolts is 1.5 in, the length of the threaded portion of the bolts is 0.75 in, and that their elastic modulus is E=30 Mpsi. The total load on the joint is 36 kip and the stiffness of the members is given as km=8.95 Mlbf/in. What is the minimum number of bolts that should be used to guard against excess proof strength with a factor of safety of np=1.2? Be sure to make an estimate for the preload.

8. A business wants to know whether two versions of an email offer have the same click-through proportion. It sent a random sample of customers an email. It randomly decided which of the two offers went in each email. In the end, it had the following data. 505 out of the 1218 customers that received the first email, clicked on the offer. 468 out of the 1221 customers that received the second email, clicked on the offer.
(a) What is the sample proportion for group 1? (round to 5 digits after the decimal place)
(b) What is the sample proportion for group 2? (round to 5 digits after the decimal place)
(c) What is the difference in the sample proportions between groups 1 and 2? (round to 5 digits after the decimal place)
(d) What is the standard error for the difference in the sample proportions? (Use σp1−p2 and round to 5 digits after the decimal place.)
(e) What is the estimate of the left end of a 95% confidence interval? (Round to 5 digits after the decimal place.)
(f) What is the estimate of the right end of a 95% confidence interval? (Round to 5 digits after the decimal place.)
(g) Do we reject or not reject the null hypothesis that the population click-through proportions are the same at the .05 level of significance? Reject Not reject
(h) Can we interpret the difference in the population proportions as a causal effect? Yes, it has a causal interpretation. or No, it does not have a causal interpretation.

Beryllium-8 is an unstable isotope and decays into two α particles, which are helium nuclei with mass 6.68×10−27kg. This decay process releases 1.5×10−14J of energy. For this problem, let's assume that the mass of the Beryllium-8 nucleus is just twice the mass of an α particle and that all the energy released in the decay becomes kinetic energy of the α particles.
If a Beryllium-8 nucleus is at rest when it decays, what is the speed of the α particles after they are released? (My answer = 1.5 x 10^6)
If the Beryllium-8 nucleus is moving in the positive x-direction with a speed of 1.0×106 m/s when it decays, what is the speed of the slower-moving α particle after it is released? Assume that the α particles move entirely in the x-direction.
