Different hotels in a certain area are randomly selected, and their ratings and prices were obtained online. using technology, with x representing the ratings and y representing price, we find that the regression equation has a slope of 135 and a y-intercept of - 388.what is the equation of the regression line?

Step-by-step explanation:

The equation of the regression line has the general form , where Y is the dependent variable , X is the independent variable , b is the slope of the line and a is the y-intercept.

Given : The slope of regression equation :

The y-intercept :

Then , the equation of the regression line is given by :-

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
