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

Answer 1
Answer:

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.

Simplify 2m - [n - (m - 2n)]. -3m - n 3m - n -3m - 3n 3m - 3n

Answers

If you would like to simplify 2m - [n - (m - 2n)], you can do this using the following steps:

2m - [n - (m - 2n)] = 2m - [n - m + 2n] = 2m - n + m - 2n = 3m - 3n

The correct result would be 3m - 3n.

Answer:

to simplify 2m - [n - (m - 2n)], you have to go though this steps:

2m - [n - (m - 2n)] = 2m - [n - m + 2n] = 2m - n + m - 2n = 3m - 3n

A cat is stuck in the tree and the fire department needs a ladder to rescue the cat. The fire truck available has a 95-foot ladder, which starts 8 feet above ground. Unfortunately, the fire truck must park 75 feet away from the tree. If the cat is 60 feet up the tree, does the cat get rescued? If not, what ladder length is need to allow the cat to be rescued?Group of answer choices
A. No because an 117-foot ladder is needed but the truck has only a 95-foot ladder.
B. No because an 96-foot ladder is needed but the truck has only a 95-foot ladder.
C. Yes because only a 75-foot ladder is needed and the truck has a 95-foot ladder.
D. Yes because only a 91-foot ladder is needed and the truck has a 95-foot ladder.

Suppose the circumference of a circle is 8π. What is its area?

Answers

Circumference = (π) x (diameter)
Circumference = 8π
(π) x (diameter) = 8π
Diameter = 8
Radius = 4

Area = π x (Radius)²
Area = π x (4)²
Area = π x (16) = 50.27 units² (rounded)
Well, its diameter would be 8, making its radius 4. The formula for finding the area of a circle is π x radius^2. So, the area would be ^2.
