Explain how the respiratory center accommodates rising and falling blood pH resulting from carbon dioxide.

I need an analysis and a complete description of the physics of the mass and magnet falling through the conducting tube demonstration.

Nonconstant Dividend Growth Valuation A company currently pays a dividend of $3.8 per share (D0 = $3.8). It is estimated that the company's dividend will grow at a rate of 24% per year for the next 2 years, and then at a constant rate of 5% thereafter. The company's stock has a beta of 1.4, the risk-free rate is 6.5%, and the market risk premium is 2%.

What is your estimate of the stock's current price? Do not round intermediate calculations. Round your answer to the nearest cent.

Estimate: GPA = β0 + β1GRE + ε, where GRE is a student’s score on the math portion of the Graduate Record Examination (GRE) score and GPA is the student’s grade point average in graduate school. [You may find it useful to reference the t table.] picture

a. Construct the 90% confidence interval for the expected GPA for an individual who scored 720 on the math portion of the GRE. (Round regression estimates to at least 4 decimal places, "tα/2,df" value to 3 decimal places, and final answers to 2 decimal places.) b. Construct the 90% prediction interval for GPA for an individual who scored 720 on the math portion of the GRE. (Round regression estimates to at least 4 decimal places, "tα/2,df" value to 3 decimal places, and final answers to 2 decimal places.)

Which of the following would be most likely to increase the supply of loanable funds and lead to low interest rates?

Hi. I am running into trouble solving the problem below and would greatly appreciate a step-by-step explanation on how to arrive at the correct answers and explanations:

SHIELD, Inc., uses a standard costing system and develops its overhead rates from the current annual budget. The budget is based on an expected annual output of 120,000 units requiring 480,000 direct labor hours. (Practical capacity is 500,000 hours.) Annual budgeted overhead costs total $787,200, of which $556,800 is fixed overhead. A total of 119,400 units using 478,000 direct labor hours were produced during the year. Actual variable overhead costs for the year were $230,600, and actual fixed overhead costs were $556,250.

1. Compute the fixed overhead spending and volume variances. How would you interpret the spending variance? Discuss the possible interpretations of the volume variance. Which is most appropriate for this example?

2. Compute the variable overhead spending and efficiency variances. How is the variable overhead spending variance like the price variances of direct labor and direct materials? How is it different? How is the variable overhead efficiency variance related to the direct labor efficiency variance?

Note: please try to give your calculations and explanations on Word or excel sheet as handwriting is sometimes difficult to read.

I would appreciate detailed calculations so I can better understand how to arrive at the correct answer.

1. You bought a $1,000 par GM callable bond in January 2020 that is callable in 2025 at par. It has a coupon rate of 3.2%/year. When is GM likely to call the bond?
2. You bought a $1,000 par Southern Company bond on April 1. The bond pays a coupon rate of 4%/year semiannually on December 1 and June 1. How much accrued interest did you pay?

During 2014 to 2025, U.S. population is projected to grow by close to 8.6%, from about 319 million to 346 million. The population under age 18 is projected to grow by only 5%, while the population aged 65 and over is projected to grow by 41%. (The Complexities of Physician Supply and Demand: Projections from 2014 to 2025, Association of American Medical Colleges, Submitted by: IHS Inc. April 5, 2016) In 2011, the baby boom generation, or those people born between 1946 and 1964, which comprises approximately 75 million individuals, will begin to turn 65. By 2030, it is projected that approximately 70 million people, or 20% of the population, will be older than 65 (U.S. Census Bureau, 1996). Older adults, defined as people aged 65 years and older, possess greater cancer incidence and mortality rates compared to younger people. Approximately 60% of all cancers occur in the older adult population, resulting in an incidence rate that is 10 to 11 times higher than in the younger population (Ershler, 2003; Yancik & Ries, 2004). The risk of developing cancer is 8%–9% in people age 40–59, with a dramatic increase in risk of 20%–30% in people older than 60 years of age (Malik, 2004). According to Edwards et al. (2002), if current cancer incidence rates were applied to the population projections for the next five decades, the number of patients with cancer would double from 1.3 million to 2.6 million between 2000 and 2050 because of population growth and aging. These projections have a direct impact on future health care in research, practice, and educational settings (Cancer and the Aging Population, Diane G. Cope, PhD, ARNP, BC, AOCNP) Other facts: Total Oklahoma population: 3,751,351 (Population Demographics for Oklahoma 2017 and 2016 content provided by the US Census bureau for the years 2010, 2011, 2012, 2013, 2014 and 2015, 2016).Number of new cases of cancer (cancer incidence) is 454.8 per 100,000 men and women per year (based on 2008-2012 cases). Question: It appears that the above scenarios present a business opportunity to build a not-for-profit cancer hospital or clinic in Oklahoma. Is it a creative idea - Why or why not?

a) A bond is offering 10 semi-annual payments of $50 until maturity in 2025, when the principal, $1000 will be paid.
What is the current value of the bond given that the yield of bonds with similar risk is 8% (annual effective yield- semi-annual yield is (1.08)1/2 -1 = 0.039)

b) How will this price change if the appropriate annual yield rises to 9%?

c) For which yield will the price be exactly $1000 (face or par value?).

Note* Please only attempt this question if you know about it. I have seen a sample and it can be calculated without the depreciation amount.
