Given the line of best fit for a set of data points with the equation y = 5x – 2.5,
what is the residual for the point (5, 26)?

a. –3.5

b. –26

c. 3.5

d. 26

The correct option is C.

Step-by-step explanation:

The equation of line of best fit for a set of data is

The estimated value of the function at x=5 is

The point of the data is (5,26). It means the observed value at x=5 is 26.

The formula for residual is

Residual value = Observed value - Estimated value

Therefore, the correct option is C.

correct

step-by-step explanation:

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
