Question

In january 2007, there were 71,000 registered gasoline-electric hybrid cars in the united states. in 2004, there were only 29000 registered gasoline-electric hybrids predict number in 2010? A) 92,000

B) 98,000
C) 104,000
D) 110,000

Answer 1

To predict the number of registered gasoline-electric hybrid cars in 2010, we can use a linear regression model based on the given data. The rate of increase in the number of registered hybrid cars from 2004 to 2007 is calculated, and this rate is used to predict the number of hybrids in 2010. The predicted number of registered hybrids in 2010 is approximately 113,000.

Step-by-step explanation:

To predict the number of registered gasoline-electric hybrid cars in 2010, we can use a linear regression model based on the given data.

First, we calculate the rate of increase in the number of registered hybrid cars from 2004 to 2007:

• Rate of increase = (Number of registered hybrids in 2007 - Number of registered hybrids in 2004) / (Year 2007 - Year 2004)
• Rate of increase = (71,000 - 29,000) / (2007 - 2004) = 14,000 hybrids per year

Next, we can use this rate of increase to predict the number of registered hybrids in 2010:

• Predicted number of hybrids in 2010 = Number of registered hybrids in 2007 + (Rate of increase * (Year 2010 - Year 2007))
• Predicted number of hybrids in 2010 = 71,000 + (14,000 * (2010 - 2007)) = 71,000 + (14,000 * 3) = 71,000 + 42,000 = 113,000

Therefore, we can predict that the number of registered gasoline-electric hybrid cars in the United States in 2010 would be approximately 113,000.
