Answer:

A

Explanation:

Correlation shows the association between two variables for example x and y. A positive correlation means as x increases or decreases y equally increases or decreases while a negative correlation means as x increases, y decreases vice versa with correlation coefficient r between -1 ≤ r ≤ 1. Correlation with coefficient zero shows not relation with the two variables. As r approaches 1 the correlation approaches perfect positive correlation while as r approaches -1 the correlation approaches perfect negative correlation.

Correlation only show association but not tell whether x causes y or the situation is cause by some unseen third factor.

Answer:

Explanation:

The computation of real gross domestic product is shown below:-

Goods     Price base year   Quantity current year   Expenditure

                    2012                      2013

A                    $2.00                  600                             $1,200

                                                                               ($2.00 × 600)

B                    $4.00                  900                             $3,600

                                                                               ($4.00 × 900)

C                    $2.00                  300                              $600

                                                                               ($2.00 × 300)

Real Gross domestic product                                     $5,400

Therefore, Real GDP is the sum value of all the final goods and services generated by an economy in a given year, which accounts for inflation. The estimate is based on the prices of a selected base year.

How do economists think private ownership most affects property maintenance??
kaheart [24]
The economists think about the pros and cons of the relation between the private ownership and the property maintenance. The property maintenance level depends on the level of the property owner responsibility which can affect the value of the property itself. There is a benefit to the private ownership if the private owner is a responsible one. A loss will occur if the private owner is not responsible.
