Multiple myeloma, or plasma cancer, is characterized by increase blood vessel formulation (angiogenesis) in the bone marrow that is a predictive factor in survival. One treatment approach used for multiple myeloma is stem cell transplantation with the patient’s own stem cells.

Cigarettes are proven to lead to serious negative health effects for both smokers and those exposed to the second-hand smoke. In an effort to reduce smoking, the government requires the suppliers of cigarettes to pay a per-unit tax on each pack of cigarettes sold. Which of the following statement below is true regarding who would be most against this tax policy? Assume that the degree of opposition to the tax corresponds exactly to the increase in price paid by the buyers or the decrease in price received by the sellers for cigarettes, so you should consider how the tax changes those prices when selecting your answer. The correct answer depends on the price elasticity of demand, so explicitly state whether demand for cigarettes is price elastic or price inelastic and provide your reasoning. Support your answer with an illustration on a supply and demand graph and fully explain. Illustrate with a price elastic or price inelastic demand curve based on the reasoning provided, show the supply curve before and after the tax, and show how the incidence of the tax is shared between buyers and sellers of cigarettes (i.e the tax paid by consumers and received by sellers before and after the tax).

2. Sensory isolation chambers are used to examine the effects of mild sensory deprivation. The chamber is a dark, silent tank where subjects float on heavily salted water and are thereby deprived of nearly all external stimulation. Sensory deprivation produces deep relaxation and had been shown to produce temporary increases in sensitivity for vision, hearing, touch, and even taste. The following data represent hearing threshold scores for a group of subjects who were tested before and immediately after one hour of deprivation. A lower score indicates more sensitive hearing. Do these data indicate that deprivation has a significant effect on hearing threshold? Test at the .05 level of significance with two tails.

Refi Corporation is planning to repurchase part of its common stock by issuing corporate debt. As a result, the firm’s debt-equity ratio is expected to rise from 40 percent to 50 percent. The firm currently has $3.5 million worth of debt outstanding. The cost of this debt is 7 percent per year. The firm expects to have an EBIT of $1.34 million per year in perpetuity and pays no taxes. |
| a. |
What is the market value of the firm before and after the repurchase announcement? (Do not round intermediate calculations and enter your answers in dollars, not millions of dollars, rounded to the nearest whole number, e.g., 1,234,567.) |
| b. | What is the expected return on the firm’s equity before the announcement of the stock repurchase plan? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.) |
| c. | What is the expected return on the equity of an otherwise identical all-equity firm? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.) |
| d. | What is the expected return on the firm’s equity after the announcement of the stock repurchase plan? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.) |

Two carts sit on a horizontal, frictionless track; the spring between them is compressed. The small cart has mass m, and the mass of the larger cart is M = 5.29m. NOTE: Every velocity needs magnitude and direction (given by the sign).
a) Suppose the carts are initially at rest, and after the "explosion" the smaller cart is moving at velocity v = +4.88 m/s. - Find the velocity of the larger cart. V =
Assume now that the mass of the smaller cart is m = 8.91 kg. Assuming there is no loss of energy: find the energy stored in the spring before the explosion. Wk =
If the spring has spring constant k = 935 N/m: find x, the distance the spring was compressed before the "explosion".
b) Suppose the carts are initially moving together, with the spring compressed between them, at constant velocity vo = +9.39 m/s. After the "explosion", the smaller cart is moving at velocity v = +4.88 m/s. Find the velocity of the larger cart.
c) Suppose now that the small cart (mass m) is initially moving at velocity vo = +3.3 m/s. At what velocity would the large cart (mass 5.29m) have to be moving so, when they collide and stick together, they remain at rest?
If you can show the work/ provide explanation I would greatly appreciate it :) Thanks

A receiving operator for a large grocery store is analyzing her operations. Trucks arrive to the loading dock at an average rate of four per hour for each day. The cost of operating a truck is estimated to be $75 per hour. Trucks are met by a two-person crew, the crew can unload the truck in an average of 9 minutes. The payroll associated with each crew member is $18/hour. It is possible to install new equipment to help the crew operate more efficiently, decreasing the unloading time from 9 minutes to 7 minutes per truck. Rental of this equipment would increase the daily cost of the operation by $200 per day. Assume each day is an 8-hour shift. Should the new equipment be installed?
a) Consider the performance of the crew before the new equipment is installed. On average, how many trucks are in the system (to the nearest 0.01 trucks) given the arrival and service rates?
b) Consider the performance of the crew before the new equipment is installed. On average, how many hours (to the nearest 0.01 hours) does each truck spend in the system given the arrival and service rates?
c) Consider the performance of the crew before the new equipment is installed. Basing your cost on the number of trucks in the system, what is the total system cost (to the nearest dollar) per day (crew cost and truck cost)?
d) Consider the performance of the crew after the new equipment is installed. On average, how many trucks (to the nearest 0.01 trucks) are in the system given the arrival and the new service rate?
e) Consider the performance of the crew after the new equipment is installed. On average, how many hours (to the nearest 0.01 hours) does each truck spend in the system given the arrival and the new service rate?
f) Consider the performance of the crew after the new equipment is installed. Basing your cost on the number of trucks in the system, what is the total system cost (to the nearest dollar) per day (crew cost and truck cost)? g) Based on your cost analysis - is it worth it to install the new equipment?

Most sports injuries are immediate and obvious, like a broken leg. However, some can be more subtle, like the neurological damage that may occur when soccer players repeatedly head a soccer ball. To examine effects of repeated heading, McAllister et al. (2013) examined a group of football and ice hockey players and a group of athletes in noncontact sports before and shortly after the season. The dependent variable was performance on a conceptual thinking task. Following are hypothetical data from an independent-measures study similar to the one by McAllister et al. The researchers measured conceptual thinking for contact and noncontact athletes at the beginning of their first season and for separate groups of athletes at the end of their second season.
|
Before the first season |
After the second season |
|
|
Contact Sport |
n = 20 M = 9 |
n = 20 M = 4 |
|
Noncontact Sport |
n = 20 M = 9 |
n = 20 M = 8 |
What are the factors and their levels for this study? Choose from the following and enter the letter only:
a. sports type
b. time
c. before the first season/after the second season
d. contact/noncontact
Factor A (rows): ________ and levels ________
Factor B (columns): ______ and levels _________
Interpret the data (you may want to do draw and upload your graph first, in the following question). Which factors do we expect to be significant?
Factor A (rows): _____
s. significant or
n. not significant
and why? ____
a. there is a row mean difference
b. there is a column mean difference
c. the lines are not really parallel
d. the lines are basically parallel
Factor B (columns): _____
s. significant
n. not significant
and why?_____
a. there is a row mean difference
b. there is a column mean difference
c. the lines are not really parallel
d. the lines are basically parallel
Interaction factor AxB: significant or not significant _____
s. Significant
n. Not significant
and Why? _____
a. there is a row mean difference
b. there is a column mean difference
c. the lines are not really parallel
d. the lines are basically parallel
( if you could show as much work as possible that would be great, I'm really confused on this question)
