Question

A team of researchers recorded the number of foxes (x) and rabbits (y) in a certain forest every autumn for twenty years. They used the data to make a scatter plot. Then, they used a computer to find that the equation of the line of best fit is y equals negative forty x plus six thousand.

Based on the equation of the line of best fit, y equals negative forty x plus six thousand, what is a justifiable prediction of the number of rabbits when seventeen foxes are counted?

six thousand, six hundred eighty

five thousand, three hundred twenty

six hundred eighty

one hundred fifty

Please @happytales finish

Answer 4

If y=40x+6000

5318.8 foxes.

Answer 5

So B?

Answer 6

Yes, B. is your answer

Answer 7

Can you help with another one?

Answer 8

A researcher justified the following conclusion with a scatter plot and a line of best fit.

As the number of siblings a student has increases, the student's score on a standardized test decreases.

Let x represent the number of siblings and y represent the standardized test score. Based on the conclusion above, which of these could be the equation of the line of best fit for the researcher's data?

y equals zero point zero five x plus fifty

y equals zero point one x minus thirteen

y equals negative zero point one two x plus thirty-two

y equals one point five x plus sixteen

Answer 9

Lets say:

x= Number of Siblings
y= Test scores

If you wanted to create scatter plot, it would look something like this:




If the scores decrease with the increasing number of siblings, the slope will be negative.

ans=D.
