Answer:

36% of the variability in electric bills can be explained by the age of home

Explanation:

Given:

  • The correlation = 0.6

The coefficient of determination measures the proportion of variation in the dependent variable that is predictable from the independent variable.

The coefficient of determination is equal to R^{2};

In this situation we have the correlation = 0.6 , hence our coefficient is 0.6^{2} or 0.36. Therefore, 36% of the variability in electric bills can be explained by the age of home

The quantity demanded of cereal increased from 1,350 to 1,700 when the price of milk decreased from $2.05 to $1.65. What is the
Iteru [2.4K]

Answer:

-1.33

Explanation:

Cross price elasticity of demand measures the responsiveness of quantity demanded of good X to changes in price of good Y.

Cross price elasticity of demand = percentage change in quantity demanded of good X / percentage change in price of good Y

Percentage change in quantity demanded = (1700 / 1350) - 1 = 0.2593 = 25.93%

Percentage change in price = (1.65 / 2.05) - 1 = -0.1951 = -19.51%

25.93% / -19.51% = -1.33

I hope my answer helps you

In 2009, the imaginary nation of Viloxia had a population of 5,000 and real GDP of 500,000. In 2010 it had a population of 5,100
Rashid [163]

The correct answer is A. During 2009 real GDP in Viloxia grew by 2 percent, which is about the same as average U.S. growth over the last one-hundred years.

Given that in 2009, the imaginary nation of Viloxia had a population of 5,000 and real GDP of 500,000, and in 2010 it had a population of 5,100 and real GDP of 520,200, to determine the growth of real GDP in Viloxia during 2009, the the following calculations must be made:

  • Total GDP / population = real GDP
  • 500,000 / 5000 = X
  • 100 = X
  • 520,200 / 5100 = X
  • 102 = X
  • 102 - 100 = 2

Therefore, during 2009 Viloxia's GDP grew by 2 percent, which is about the same as average U.S. growth over the last one-hundred years.
