Answer: 0.8; 5
Explanation:
From the question, we are informed that people decide to save 20 percent of their incomes. We should note that the addition of the marginal prospensity to consume(MPC) and the marginal prospensity to save(MPS) will be equal to 1.
Therefore, the value of the marginal propensity to consume will be:
= 1 - 20%
= 1 - 0.2
= 0.8
The value of the spending multiplier will be calculated as:
= 1/MPS
= 1/0.2
= 5
Answer:
As robotics quickly advance, scientists say the lines between robots and humans is beginning to blur.
That means one day with robotic prosthetics that work seamlessly with a human's muscles, with tiny robots that swim in our blood streams and fix medical problems and nano-scale robots implanted in our brains, we will become robotic humans.
As scary and sci-fi as that may sound, researchers say robotics will cure diseases, make amputees feel whole again and greatly extend our lives
Explanation:
Answer:
This is a stratified random sample because a separate random sample is selected from each class
Explanation:
Stratified random sampling is an appropriate method when the population consists of mixed characteristics and you would like to ensure that every characteristic is proportionally represented in the sample. In this example, the population is the students from Central High School and the mixed characteristics are the different classes such as Freshman students, Sophomore students, Juniors and Seniors.
After the population is divided into subgroups based on characteristics, from the overall proportion of the population, you calculate how many people should be sampled in each subgroup. Random or systematic sampling can then be used to select a sample from each subgroup.
The baby boomers could change the fashion industry as they transition to senior citizens because they could motivate designers to create products that meet their needs. For example, they might motivate shoe designers to design shoes that are similar to those worn by the younger generation but perhaps with more comfort and lower heels. Therefore, they will maintain their sense of fashion, but in a rather different manner.
Answer:
$3,667.44
Explanation:
The amount you would be willing to pay today can be determined by finding the present value of the cash flows
Present value is the sum of discounted cash flows
Present value can be calculated using a financial calculator
Cash flow each year from year 1 to 4 = $25
Cash flow in year 5 = $25 + $5000
I = 7%
Present value = $3,667.44
To find the PV using a financial calculator:
1. Input the cash flow values by pressing the CF button. After inputting the value, press enter and the arrow facing a downward direction.
2. after inputting all the cash flows, press the NPV button, input the value for I, press enter and the arrow facing a downward direction.
3. Press compute
