The time (in years) after reaching age 60 that it takes an individual to retire is approximately exponentially distributed with a mean of about five years. Suppose we randomly pick one retired individual. We are interested in the time after age 60 to retirement. a. Define the random variable. X= _________________________________. b. IsXcontinuous or discrete? c. X~ = ________ d. μ= ________ e. σ= ________ f. Draw a graph of the probability distribution. Label the axes. g. Find the probability that the person retired after age 70. h. Do more people retire before age 65 or after age 65? i. In a room of 1,000 people over age 80, how many do you expect will NOT have retired yet?

In order to buy a new car, you finance $23,000 with no down payment for a term of five years at an APR of 6%. After you have the car for one year, you are in an accident. No one is injured, but the car is totaled. The insurance company says that before the accident, the value of the car had decreased by 25% over the time you owned it, and the company pays you that depreciated amount after subtracting your $500 deductible. How much equity have you built up after one year? Suggestion: Use the following formula for the equity built up after k monthly payments. (Round your answer to the nearest cent.) Equity = Amount borrowed × ((1 + r)k − 1) ((1 + r)t − 1)

A 5.87-g bullet is moving horizontally with a velocity of +348 m/s, where the sign + indicates that it is moving to the right (see part a of the drawing). The bullet is approaching two blocks resting on a horizontal frictionless surface. Air resistance is negligible. The bullet passes completely through the first block (an inelastic collision) and embeds itself in the second one, as indicated in part b. Note that both blocks are moving after the collision with the bullet. The mass of the first block is 1238 g, and its velocity is +0.631 m/s after the bullet passes through it. The mass of the second block is 1623 g. (a) What is the velocity of the second block after the bullet imbeds itself? (b) Find the ratio of the total kinetic energy after the collision to that before the collision.

True or False?
1. David and Nate work for two different companies, but each performs the same job working on a loading dock. David, however, earns a higher salary than his friend Nate The difference in salary could illustrate union wages if David’s annual salary is covered by a collective bargaining agreement and Nate’s is not.
2. Critics argue that a disadvantage of the Earned Income Tax Credit is that it does not effectively target the working poor because many recipients are the teenage children of middle-income families.
3. Critics argue that a disadvantage of minimum-wage laws is that they do not effectively target the working poor because many minimum-wage workers are the teenage children of middle-income families.
4. One example of labor-market discrimination is that a firm may be less likely to interview a job candidate whose resume clearly indicates he is not a good fit for the job.

On January 1, 2017, Doone Corporation acquired 60 percent of the outstanding voting stock of Rockne Company for $528,000 consideration. At the acquisition date, the fair value of the 40 percent noncontrolling interest was $352,000 and Rockne's assets and liabilities had a collective net fair value of $880,000. Doone uses the equity method in its internal records to account for its investment in Rockne. Rockne reports net income of $330,000 in 2018. Since being acquired, Rockne has regularly supplied inventory to Doone at 25 percent more than cost. Sales to Doone amounted to $390,000 in 2017 and $490,000 in 2018. Approximately 35 percent of the inventory purchased during any one year is not used until the following year.

Researchers from the university of Kent, UK, were interested in whether collectivist or individualist attitudes are related to one’s intent to comply with social distancing and safety guidelines during COVID-19. Participants were classified as either collectivist or individualist, and rated their intent to comply with guidelines on a scale from 1-5, where 1 is definitely not and 5 is definitely yes. Please conduct an independent-groups t test to determine if there is a significant difference in intention to comply between individualists and collectivists.
In addition, please:
- report cohen’s d
- report r^2
- conduct and interpret an F-MAX test
- include 95% confidence intervals
- report your answer in words that directly address the research

Consider a firm as follows: Assume that the firm has no debt. The cash flows are received at the end of each year and are perpetual. Cost of equity capital for an unlevered firm, r0, is 20%. The first cash-flow will be received one year from today. All calculations for valuation are done today. Firm value is defined as collective value of debt and equity.
Sales = $ 500,000
Cash Costs = 360,000
Operating Income = 140,000
Tax @ 34% -47,600
Unlevered cash flow (UCF) $ 92,400
To illustrate that financing has no impact on firm value if
there are no taxes (i.e. financing affects firm value purely
because the interest payments generate tax-savings), and to further
illustrate the equivalence of various valuation methods.Assume the
the firm has$ 100,000 of debt @ 10% and the tax rate is zero.Find
the firm value using

On January 1, 2017, Doone Corporation acquired 60 percent of the outstanding voting stock of Rockne Company for $600,000 consideration. At the acquisition date, the fair value of the 40 percent noncontrolling interest was $400,000 and Rockne's assets and liabilities had a collective net fair value of $1,000,000. Doone uses the equity method in its internal records to account for its investment in Rockne. Rockne reports net income of $390,000 in 2018. Since being acquired, Rockne has regularly supplied inventory to Doone at 25 percent more than cost. Sales to Doone amounted to $450,000 in 2017 and $550,000 in 2018. Approximately 35 percent of the inventory purchased during any one year is not used until the following year.
