Answer:

What is a positive economic statement?

Positive economics is objective and fact-based where the statements are precise, descriptive, and clearly measurable.

What is a normative economic statement?

Normative economics focuses on the ideological, opinion-oriented, prescriptive, value judgments, and "what should be" statements aimed toward economic development, investment projects, and scenarios.

Provide a real world example of each (other than those given in the chapter)

An example of normative economics would be, "We should cut taxes in half to increase disposable income levels." By contrast, a positive or objective economic observation would be, "Based on past data, big tax cuts would help many people, but government budget constraints make that option unfeasible." The provided example is a normative economic statement because it mirrors value judgments. This particular judgment assumes that disposable income levels must be increased

Positive economics deals with objective explanation and the testing and rejection of theories. For example:

A fall in incomes will lead to a rise in demand for own-label supermarket foods

If the government raises the tax on beer, this will lead to a fall in profits of the brewers.

The rising price of crude oil on world markets will lead to an increase in cycling to work

A reduction in income tax will improve the incentives of the unemployed to find work.

A rise in average temperatures will increase the demand for sun screen products.

Higher interest rates will reduce house prices

Cut-price alcohol has increased the demand for alcohol among teenagers

A car scrappage scheme will lead to fall in the price of second hand cars

Please explain why each statement would be considered either positive or normative:

Common observations indicate that discussions around public policies typically involve normative economic statements. A higher degree of disagreements persists in such discussions because neither party can clearly prove their correctness.

Though normative statements are generalized and subjective in nature, they act as the necessary channels for out-of-the-box thinking. Such opinions can form the foundation for any necessary changes that may have the potential to completely transform a particular project. But normative economics cannot be the sole basis for decision-making on key economic fronts. Positive economics fill in for the objective angle that focuses on facts and cause-and-effect. Coupled with positive economics, normative economics may be useful in establishing, generating, and fulfilling new ideas and theories for different economic goals and perspectives.

A clear understanding of the difference between positive and normative economics may lead to better policy-making if policies are made based on a balanced mix of facts (positive economics) and opinions (normative economics). Nonetheless, numerous policies on issues ranging from international trade to welfare are at least partially based on normative economics.

Please include sources with your posting:

Normative economics focuses on the value of economic fairness, or what the economy "should be" or "ought to be."

While positive economics is based on fact and cannot be approved or disapproved, normative economics is based on value judgments

<u>Question:</u>

Find the number of real number solutions for the equation. x^2 + 5x + 7 = 0

<u>Answer:</u>

The number of real solutions for the equation x^{2}+5 x+7=0 is zero

<u>Solution:</u>

For a Quadratic Equation of form : a x^{2}+b x+c=0  ---- eqn 1

The solution is x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}  

Now , the given Quadratic Equation is x^{2}+5 x+7=0  ---- eqn 2

On comparing Equation (1) and Equation(2), we get

a = 1 , b = 5 and c = 7

In x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a} , b^2 - 4ac is called the discriminant of the quadratic equation

Its value determines the nature of roots

Now, here are the rules with discriminants:

1) D > 0; there are 2 real solutions in the equation

2) D = 0; there is 1 real solution in the equation

3) D < 0; there are no real solutions in the equation

Now let solve for given equation

D= b^2 - 4ac\\\\D = 5^2 - 4(1)(7)\\\\D = 25 - 28 \\\\D = -3

Since -3 is less than 0, this means that there are 0 real solutions in this equation.

PHYSICS As a ray of light meets a mirror, the light
Lady bird [3.3K]
<h3>Answer:  37 degrees</h3>

========================================================

Explanation:

The angle of incidence is equal to the angle of reflection. The angle of light coming in is the same as the angle of light bouncing out. Each angle is made with the dashed line as the diagram shows.

So angle RMI = 106 is bisected, i.e. divided in half, to get

  • Angle RMN = 53
  • Angle NMI = 53

since 106/2 = 53

Then notice that the horizontal dashed line is perpendicular to the vertical mirror. This means angle NMJ is a 90 degree angle and,

angle RMJ = (angle NMJ) - (angle RMN)

angle RMJ = 90 - 53

angle RMJ = 37 degrees

----------

In short: divide 106 in half to get 53, then subtract it from 90

A quiz has thirty questions whose answers can only be correct or incorrect.
satela [25.4K]

Using a system of equations, it is found that Gina got 22 questions correct in the test.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

  • Variable x: Number of questions she got correct.
  • Variable y: Number of questions she got wrong.

The test has 30 questions, hence:

x + y = 30 -> y = 30 - x.

She scored 152 points, hence, considering the value of each question:

8x - 3y = 152.

Since y = 30 - x:

8x - 3(30 - x) = 152

11x = 242

x = 242/11

x = 22

Gina got 22 questions correct in the test.

Whats has the same slope of 6x-3y=9
Crank

Answer:


Step-by-step explanation:

when you put it into slope intercept form you get

y=2x-3

2 is the slope, so

y=2x+3 would have the same slope which means these lines are parallel.
