Hello there, can you help me solve the problem with two subparts (b and c)? Thank you Problem: (the image is attached) Subparts: b. Find the least-squares curve of the form above to fit the data (4, 1.57), (6, 2.05), (8, 2.5), (10, 2.7), (12, 3.1), (14, 3.6), (16, 3.8), and (18, 4.35), where x and y represent sales and costs in thousands. Produce a graph that shows the data pts and the graph of the cubic approximation. y = __x + (__)x2 + (__)x3 (round to six decimal places as needed.) c. (the image is attached) (round to four decimal places)

Question
Hello there, can you help me solve the problem with two subparts (b and c)? Thank you
Problem: (the image is attached)
Subparts:
b. Find the least-squares curve of the form above to fit the data (4, 1.57), (6, 2.05), (8, 2.5), (10, 2.7), (12, 3.1), (14, 3.6), (16, 3.8), and (18, 4.35), where x and y represent sales and costs in thousands. Produce a graph that shows the data pts and the graph of the cubic approximation.
y = __x + (__)x2 + (__)x3
(round to six decimal places as needed.)
c. (the image is attached)
(round to four decimal places)

Transcribed Image Text:c. If a machine learned the curve you found in (b), what output would it provide for an
input of x = 13?

Transcribed Image Text:A simple curve that often makes a good model for the variable cost of a company, as a
2
function of the sales level x, has the form y =B₁x + ß₂ײ + ß3׳. There is no constant term
because fixed costs are not included. Complete parts (a) through (c).
