How do built-in stabilizers work to reduce rises and falls in the level of nominal GDP?

What else was going on in US history at the time the Vietnam Veterans Memorial was being built?

For today's lab we will be using the Car Object Class which we built in Lab 1. I have attached my solution if you would prefer to use my solution instead of your own solution.

We will working on remembering how to build sub-classes and user interfaces. So we will be creating new Java files for:

• An Interface called GreenHouseGasser
  • Requires a method called CO2() which returns how much carbon dioxide the Object produces.
  • Make sure to update Car so that Car implements GreenHouseGasser. Cars should produce 1.5 units of CO2 for every mph the car is traveling.
• A Car sub-class called SportsCar:
  • Overrides the accelerate() method. SportsCars accelerate twice as fast as regular Cars
  • Overrides the CO2() method. SportsCars should be using a factor of 3.25 units of CO2 for every mph
• A Car sub-class called EcoCar
  • Overrides the accelerate() method. EcoCars accelerate 25% as fast as regular Cars
  • Overrides the CO2() method. EcoCars should be using a factor of .33 units of CO2 for every mph

As your are building/updating your objects, remember to test. You'll need update the Driver to test your new methods and Objects!

Submit all of your .java files in one jar or zip file.

Grading Breakdown:

• Driver tests all new methods and objects -- 25%
• Interface created correctly and Car updated to implement the Interface -- 25%
• SportsCar correctly created -- 20%
• EcoCar correctly created -- 20%
• JavaDoc comments! -- 10%

Here is the Car Object pre-made:

public class Car
{
private String name;
private int currentSpeed;
  
public Car(String inName)
{
name = inName;
}
  
public void accelerate()
{
currentSpeed += 10;
}
  
public void park()
{
currentSpeed = 0;
}
  
public void printCurrentSpeed()
{
System.out.println("Current Speed is: " + currentSpeed);
}
}

Here is the driver that is supposed to be used:

public class Driver {
  
   public static void main(String[] args) {
       // create new Audi car
       Car audi = new Car("Audi");
       // create new Nissan car
       Car nissan = new Car("Nissan");
      
       // print current speed of Audi - it is 0
       audi.printCurrentSpeed();
      
       // call the accelerate method twice on Audi
       audi.accelerate();
       audi.accelerate();
      
       // call the accelerate method once on Nissan
       nissan.accelerate();
      
       // print current speed of Audi - it is now 20 mpH
       audi.printCurrentSpeed();
       // print current speed of Nissan - it is 10 mpH
       nissan.printCurrentSpeed();
      
       // now park the Audi car
       audi.park();
      
       // print current speed of Audi - it is now 0, because the car is parked
       audi.printCurrentSpeed();
   }
}

Are negative real yields on Treasurys expected to change in the near future?

Which of the following is characteristic of metals?

Which of the following is characteristic of insulators?

Which of the following is characteristic of semiconductors?

Match each of the following answers:

Large number of carriers independent of temperature, and low electron mobility that decreases with increasing temperature.

Intermediate number of carriers independent of temperature, and high electron mobility that decreases with increasing temperature

Near zero conductors, no real mobility estimates and near zero conductivity.

None of the above.

A research Van de Graaff generator has a 1.98-m-diameter metal sphere with a charge of 4.75 mC

on it.

a) What is the potential near its surface?

MV

b) At what distance from its center is the potential 1.02

MV

?

c) An oxygen atom with 3

missing electrons is released near the Van de Graaff generator. What is its energy in MeV

at this distance?

MeV

We performed a linear regression analysis between number of times on phone per drive and number of near accidents. The equation is Y= 0.320 + 0.943X, where Y is the number of times on phone per drive and X is the number of near accidents. calculate the p-value and give a conclusion.

Based on this data calculate:

a) M1 +

b) M2

c) M3

d) M2+

Investment advisors agree that​ near-retirees, defined as people aged 55 to​ 65, should have balanced portfolios. Most advisors suggest that the​ near-retirees have no more than​ 50% of their investments in stocks.​ However, during the huge decline in the stock market in​ 2008, 23​% of​ near-retirees had 85​% or more of their investments in stocks. Suppose you have a random sample of 10 people who would have been labeled as​ near-retirees in 2008. Complete parts​ (a) through​ (d) below.

a. What is the probability that during 2008 none had 85​% or more of their investment in​ stocks? The probability is . ​(Round to four decimal places as​ needed.)

b. What is the probability that during 2008 exactly one had 85​% or more of his or her investment in​ stocks? The probability is . ​(Round to four decimal places as​ needed.)

c. What is the probability that during 2008 two or fewer had 85​% or more of their investment in​ stocks? The probability is . ​(Round to four decimal places as​ needed.)

d. What is the probability that during 2008 three or more had 85​% or more of their investment in​ stocks? The probability is . ​(Round to four decimal places as​ needed.)
