A distributor of cosmetics has sales representatives in various metropolitan areas all over the country. They have collected data over the past year looking for a relationship between the number of months of Experience a sales representative has in cosmetic sales (X), and the monthly sales volume (Y, in thousands of dollars) for the sales representative in a given month. The data was gathered from representatives with 0 - 60 months experience. A scatterplot of the data showed a positive linear relationship, and a simple regression model was determined. The results are given by:.

The results are given by:.

the equation, y = ax+b.

where a = the slope of the line and b is the intercept or the value of Y when X = 0.

Step-by-step explanation:

The simple linear regression is a model for estimating the relationship that exists between an independent variable and a dependent variable.  The model uses a straight line for two quantitative variables.  With a scatter graph, the line of best fit is given as the equation, y = bX + a.  This equation determines the values of b and a for a dataset of two variables.  It can also be used to estimate the value of Y for a given value of X.

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.

im with everythinglos so yeahhhhh
