...Running Head: QLT1 Task 1 Rev 1 QLT1 Task 1 Rev 1 QLT1 Task 1 Mary is going away to college. In order to stay in touch with her family and friends she needs to get a cell phone with a calling plan. At this time Mary isn’t sure what her monthly phone usage is going to be. After consulting with her college friends, she estimates her usage will be between 200 and 900 minutes per month. A local phone company offers two basic calling plans: Plan A. offers a package consisting of monthly charge of $50.00 and $0.10 for each minute. Plan B. offer is a monthly fee of $15.00 and $0.18 per minute. The phone company charges for actual time used for both plans, so if Mary used .75 Min for talk time she would pay for actual time used [(.75) x per minute rate] Plan A The cost of plan (Y) X= phone usage in minutes (this is our variable) Y=50 + 0.10(x). The cost of plan A (Y) is $50 base charge plus $.10 per each minute (x) represented in a linear equation. Plan B X= phone usage in minutes (this is our variable) Y=15 + .18(x). The cost of plan B (Y) is $15 base charge plus $.18 per each minute (x) represented in a linear equation. 1. Which plan would offer greater savings if Mary’s monthly phone usage was 200 min?

Task 3 Community Health Wgu

...Community and Population Health By Malka Molly Hayman, RN Task three Communicable disease outbreak of the Measles Communicable disease outbreak occurs when there is a larger then expected incidence of a disease. It can affect a small group or thousands of people in a region. In some instances even just two independent cases can lead to an outbreak, eventually leading to an epidemic, or pandemic which refers to a global outbreak. Measles is a communicable disease that is highly contagious according to the World Health Organization (WHO). The good news is that it is a preventable disease, because there is a vaccine that is available to prevent people from contracting it. One complication that arises is when some people refuse to immunize their children, (sometimes due to religious reasons or other beliefs) then the risk of an outbreak certainly increases. Another complication is when false information circulates, (for example there was a case where someone claimed that a particular immunization could cause Autism), then people tend to jump to conclusions and are quick to blame others, rather than do their due diligence. Additional complications arise in poor countries where immunization is not readily available, and in cases like these an outbreak is more highly possible. Measles has the following epidemiological indicators which show that it is considered a highly infectious, acute viral illness that is typically confirmed via lab tests. Typically a rash...

Wgu Let 1 Task 3

... LET1 Task 3 - When discussing leadership it’s important to know that there are 5 bases of power. Those 5 bases of power are coercive, reward, legitimate, referent, and expert. Coercive can be described as someone with power using that power to make someone do something they do not want to do. Reward is just that, offering a reward. A manager might offer a reward to the employee who has the highest production rate. This, in theory, drives all employees to work harder in hopes of a reward. Legitimate power is when someone does something they are asked because of the job title or role of the person asking them. Referent power is when someone does something they are asked to do because they like or admire the person asking them to do it. Expert power involves someone’s expertise to get something done. A doctor is a good example. If a doctor tells a patient he or she needs to drink more milk, that person will more than likely comply, simply because of the doctor’s inferred expertise. Within the given scenarios, the five bases of power are displayed. The paragraph that discusses employee 1 and the marketing manager describes a situation in which the coercive and reward powers are being used. The yearly bonus is the reward for employees who receive a superior rating on performance evaluations. The manager uses coercion to get the employees to work late and on their off days. The paragraph that discusses the accounting department and employee 2, who is a CPA, the......

...JET2 Task 3 A. Competition Bikes, Inc. (CBI) currently finds itself in a position in which it can feasibly expand its business. As such, the company has identified Canada as a potential market into which it may expand and has further identified Canadian Biking, Inc. (CABI) as a potential avenue of expansion. Specifically, CBI is investigating whether it should merge with CABI or instead purchase the company. This report will analyze the company’s various options with regard to such an expansion and will ultimately make a recommendation as to whether merger or acquisition of CABI would be best for CBI. A1. Capital structure refers to the money being utilized within a company, and it is divided into two types of capital: debt capital and equity capital (Kennon, 2013). Debt capital refers to the percentage of the company’s capital that is borrowed, while equity capital is money provided by the company’s shareholders (Kennon, 2013). Furthermore, equity capital is represented in two types: retained earnings and contributed capital. The latter, contributed capital is the money that was originally put forth to fund the company (Kennon, 2013). These funds were provided in exchange for stakes in the company’s ownership. Retained earnings refer to the profits that have been earned and collected from previous years and put aside to be used by the company for expansion (Kennon, 2013). As CBI looks to expand into the Canadian market, it must first determine which capital......

Although SARS’ precise origin isn’t definitively known, all current data points to small mammals know as civets as the most plausible source of human transmission. The outbreak of SARs started in November of 2002 in the Mainland Chinese Province known as Guangdong, where the civets were viewed as a delicacy. In a misguided attempt prevent panic, the Chinese government failed to inform the World Health Organization of the initial outbreak for nearly four months. Subsequently the virus was contracted by 8098 people between November 2002 and June 2003. 774 of these cases proved fatal worldwide. (Trivedi, 2013) The 3 primary factors that enabled SARS to spread so far and so fast were a lack of early reporting by Chinese officials, lack its high virulence, and international flight paths. Early awareness of SARS was severely by attempts at secrecy within the Chinese government in an attempt to prevent panic. This secrecy delayed awareness reaching both the WHO and healthcare staff, who were unaware of SARS virulence and potency. As mentioned, the SARS outbreak originated in the Guangdong Province in China. SARS was easily spread to healthcare staff who in-turn infected their friends, family, colleagues, and other patients. Also, family members would sick patients, and then......

...Student I.D. E-Mail: Western Governors University LIT1: Task 310.1.5-02, 11, 13 Situation A: The employee’s FMLA right was satisfied when he was granted the leave by the company. The employee has been employed at the company for two years prior to his request, which clearly fulfills the requirement of working a total of twelve months before the leave must be granted by the company, which employees more than fifty employees. The request for leave was for birth care, which is a valid reason to request FMLA. All of the applicable provisions of the FMLA were adequately met for this particular employee. FMLA grants twelve weeks of unpaid time off and guarantees that the employee will then be able to return to the same job at the same rate of pay. FMLA provisions do not require paid time off as a mandatory action for the company; therefore, the employee cannot expect the company to pay eleven weeks of withheld salary and the company has not violated any FMLA rules by denying that specific request. Situation B: It is apparent the 68-year-old employee is performing his work duties adequately. The employee has an above average rating; therefore, it cannot be argued that his age is affecting his quality of work.  Nothing to suggests that his work does not meet the standards of the company.  This is an example of why the Age Discrimination Act of 1967 is so important and necessary.

Option A is a home-based facility which charges $9.00 per hour that the child is at the home. Option B is a center-based facility which charges $150 for the first 20 hours and then charges $10 per hour thereafter. Due to a new promotion, Jenny will be required to work more hours away from home. Which facility will cost less for Jenny to have her son in daycare for a work week (40 hours)? B. I. h = how many hours of child care is needed = 40 f = the flat hourly rate charge t = total amount due for the week Option A: f * h = t a. 9 * 40 = $360 Option B: 150 + f(h-20) = t, for h >=20 b. 150 + 10(40-20) = $350 150 = t, for h < 20 c. 150 = total II. I set the hours to "h", the hourly fee to "f" and the total to "t". a. Option A: This option only has an hourly fee for each hour. The fee is $9 and the amount of hours is 40 so I multiplied the hours by the fee. b. Option B: This option has a flat rate of $150 for the first 20 hours and then an hourly rate of $10 thereafter.

...INT1 Task 3 Example Does More Sugar Make Lemon Sauce Runny? By N. Shane Cutler Project Design Plan Cornstarch is a common thickening agent in cooking. Plant starch is made of a mixture of amylose and amylopectin. When heated in a water-based solution, the starch molecules can unwind and then form new hydrogen bonds with other starch molecules, making a network of long molecular filaments that can hold water molecules in a gel (Holmes, 2012). The Argo Cornstarch website warns that too much sugar can interfere with thickening (Argo, 2012). Literature Review There are many different ways to thicken liquids and thickening liquids has many applications. Many experiments have been done to test different thickening methods. GVSoapCo tested 4 different substances to thicken homemade liquid hand soap: Xanthan Gum, Borax, Salt or Crothix. This experiment used the same soap recipe, substituting the different thickening agents. The experimenter then tested the thickness or runniness of the finished soap by spooning it up and drizzling it. This showed that the Crothix thickener made the thickest, smoothest soap, whereas the salt made the thinnest, runniest soap. While the spooning method was effective at showing the qualitative difference the thickening agent made, it didn’t produce quantitative measurements of the relative thickness (GVSoapCo, 2013). Foy compared low sugar pectin with traditional pectin in making grape jelly. She reported that the traditional pectin made firmer jelly......

Wgu Biochemistry Task 3

...WGU Biochemistry Task 3 A1) There are several differences between the oxygenated and deoxygenated states of hemoglobin. One difference can be seen in the conformational state of the hemoglobin protein. When oxygenated, the protein takes on the T (tense) state; and when deoxygenated, the protein takes on the R (relaxed) state (Hudon-Miller, 2012b). Another difference arises when oxygen binds to the hemoglobin, resulting in a change in the shape of the protein. In the deoxygenated state, the heme group forms a domed shape; and in the oxygenated state, the heme group takes on a planar shape (Hudon-Miller, 2012b). A2) The relationship between pH and the ability of hemoglobin to bind and release oxygen is referred to as the Bohr Effect. The blood’s pH level is greatly influenced by the carbon dioxide that is produced by most of the body’s cells during the citric cycle (Hudon-Miller, 2012d). Greater CO2 concentration lowers the blood’s pH level, making it more acidic. In turn, lower CO2 concentration increases the blood’s pH level, making it more basic. Since the lungs function involves breathing in oxygen and blowing out carbon dioxide, the lungs are absolutely crucial in maintaining the pH balance that the blood requires (Hudon-Miller, 2012d). While in the lungs, the hemoglobin becomes saturated with oxygen and slowly delivers it to the body’s tissues as it travels through the bloodstream. At the same time, the hemoglobin is also picking up the carbon dioxide that is......

...concentration decreases as blood nears the lungs, which in return causes and increase in pH . Increased pH causes increased affinity for oxygen which causes the hemoglobin to pick up oxygen entering your blood to be transported to the body’s tissue. Hemoglobin loses hydrogen ions from specific amino acids at key sites as pH rises causing slight changes in its structure that increase its ability to bind oxygen. As pH falls hemoglobin picks up hydrogen ions and its affinity for oxygen decreases. Increasing carbon dioxide concentration in your tissues cause a decrease in pH, which in turn forces hemoglobin to dump the oxygen it's carrying so your cells can use it for energy . a. 3.

...Stephen Rueden INT1 Task 3 Sub domain 114.1.1 Scientific Concepts, Theories & Inquiry 4/17/2011 Literature Review: Elasticity and Hooke’s Law: In physics, elasticity is the physical property of a material that returns to its original shape after the stress that made it deform is removed (Elasticity, para. 1). Elasticity was first studied in the late seventeenth century by the English scientist Robert Hooke (1635­1703). He made observations about elasticity using metal springs and eventually developed what is known as Hooke’s Law: The restoring force exerted by an elastic object is proportional to how far it has been distorted from its equilibrium state. Everything we associate with springs, has some place in the behavior of balls (Bloomfield, p.69). When a ball or a spring returns to its equilibrium state, it releases stored energy. Isaac Newton and the Law of Universal Gravitation: Isaac Newton (1643­1727) studied gravity and its effects on falling objects. He is most famous for the three laws of motion. Newton’s law of universal gravitation states that every point mass attracts every single other point mass by a force pointing along the line intersecting both points. The earth’s gravity exerts a downward force on the ball, called the ball’s weight. Its weight causes the ball to accelerate downward (Bloomfield p. 10). Reasoning: What does elastic mean? When a rubber band gets stretched it returns to its original shape. What is something that is not elastic? When a piece......
