Answer:
A). A real estate development company wants to estimate the probable sales of construction services on the basis of marriage rates, population movement in the region, and interest rates on construction loans.
Explanation:
Multiple regression is elucidated as the statistical technique employed to determine the association between two or more dependent or response and independent/explanatory variables.
As per the question, the multiple regression can be employed in the first situation where 'a real estate company wishes to forecast the probable sales of construction on the basis of....loans.' Multiple regression analysis would help in representing the linear relationship between these two variables that helps in ensuring effective analysis and making predictions and ensuring optimum output. Thus, <u>option A</u> is the correct answer.
A decrease in aggregate demand causes the price level to fall. If the government takes no action to
counter this, then the actual price level will be below the price level that people expected.
Individuals will eventually correct their expectations of the price level. As they do so, prices and
wages will adjust accordingly, shifting the aggregate supply curve to the right (down). For example
if wages are sticky, in light of the lower price level, firms and workers will eventually make bargains
for lower nominal wages. The reduction in wages lowers costs of production, so firms are willing to
Answer:
The boy: 8 years old
The sister: 11 years old
Explanation:
We assume that the age at present of the boy is x (years old).
As he is younger than his sister 3 years, so that his sister's present age is great than x 3 years
=> Her present age is: x + 3 (years old)
Two years ago, the boy is younger than present two years
=> The boy's age two years ago is: x - 2 (years old)
Similarly, the sister's age two years ago is: (x+3)-2 = x + 1 (years old)
As given, two years ago he was two-thirds of his sister's age, so that we have:
<em>The boy's age two years ago = </em>
<em> × the sister's age two years ago</em>
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
=> x + 3 = 8 + 3 = 11
So the present age of the boy is 8 years old, of the sister is 11 years old
