What does a residual value of 1.3 mean when referring to the line of best fit of a data set?A data point is 1.3 units above the line of best fit.
A data point is 1.3 units below the line of best fit.
The line of best fit has a slope of –1.3
The line of best fit has a slope of 1.3.

Answers

The residual value of 1.3mean when referring to the lineofbestfit of a data set is that a data point is 1.3 units above the line of a data set. This is because the given residual value is positive. So, the data point is above the best fit line.

Residual value:

  • A residual value is the standard square error which is calculated from the line of best fit.
  • If the residual value 'r' is positive it means the data point is r units above the best fit line.
  • If the residual value 'r' is negative it means the data point is r units below the best fit line.

Line of best fit:

A line of best fit refers to a line through a  plot of datapoints that best expresses the relationship between those points.

For the given residualvalue of 1.3 mean, a data point is 1.3unitsabove the line of best fit when referring to the line of best fit of a data set. This is because the residual value is positive.

So, Option A is correct.

A trampoline has an area of 49 pi square feet. what is the diameter of the trampoline?

Answers

The area of a circle is pi times the radius squared. Set up the equation pi x r squared = 49 pi square feet. Divide both sides of the equation by pi. 
r squared = 49 square feet. Take the square root of both sides. r = 7 feet.
The diameter of the trampoline is double the radius which is 14 feet.
