The scatter plot shows the relationship between the age of a car and asking price. Which statements are correct?
Responses
A A reasonable prediction for a 2 year old car is $18,000.A reasonable prediction for a 2 year old car is $18,000.
B A reasonable prediction for a 4 year old car is $15,000.A reasonable prediction for a 4 year old car is $15,000.
C The line of best fit shows that the price and age of a car have a positive association.The line of best fit shows that the price and age of a car have a positive association.
D The line of best fit can be used to make predictions of price based on the age of the car.The line of best fit can be used to make predictions of price based on the age of the car.
E The line of best fit gives the best approximation of the association between age of a car and price.
Statements C, D, and E are correct.
C. The line of best fit shows that the price and age of a car have a positive association. This means that as the age of the car increases, the asking price also tends to increase.
D. The line of best fit can be used to make predictions of price based on the age of the car. The line of best fit can be used to estimate the expected asking price for a car of a certain age, based on the trend shown in the scatter plot.
E. The line of best fit gives the best approximation of the association between age of a car and price. The line of best fit is calculated to minimize the distance between the actual data points and the predicted values, making it the best approximation of the overall relationship between age of a car and price.
are you sure?
I apologize for the confusion. Let me re-evaluate the statements:
A. A reasonable prediction for a 2-year-old car is $18,000.
B. A reasonable prediction for a 4-year-old car is $15,000.
C. The line of best fit shows that the price and age of a car have a positive association.
D. The line of best fit can be used to make predictions of price based on the age of the car.
E. The line of best fit gives the best approximation of the association between age of a car and price.
Based on the information provided, I cannot determine the accuracy of statements A and B, as no specific data or trend is given in the question. However, I can confirm that statements C, D, and E are correct.
Olivia is growing roses and keeps track of how much fertilizer (in ounces) she adds to the soil and how many blooms each rose bush has. She finds a linear relationship that can be modeled by the equation y=1.345+4. What does the 1.345 mean in the context of the problem?
Responses
A That she must add 1.345 ounces of fertilizer every day.That she must add 1.345 ounces of fertilizer every day.
B That every day she found an additional 1.345 blooms on her rose bushes.That every day she found an additional 1.345 blooms on her rose bushes.
C That for every additional bloom on the rose bush she added 1.345 ounces of fertilizer.That for every additional bloom on the rose bush she added 1.345 ounces of fertilizer.
D That for every ounce of fertilizer she adds there is an additional 1.345 blooms on the rose bush.
