Based on the scatter plot for this data, we can logically deduce that the association between them is a <u>positive association</u>.
<h3>What is a scatter plot?</h3>
A scatter plot can be defined as a type of graph which is used to graphically represent the values of two (2) variables, with the resulting points showing any association (correlation) between the data set.
<h3>Part A.</h3>
Based on the scatter plot for this data, we can deduce that the association between them is a <u>positive association</u> because the price and customer rating increases together.
<h3>Part B.</h3>
An example of a data point which would affect the appropriateness of using a linear regression model to fit all the data is car price of $4,601 and customer rating of 100.
<h3>Part C.</h3>
An example of a car that is cost effective and rated highly by customers is the one with a customer rating of 100 and sold at $3,500.

Answer:
Step-by-step explanation:
Since this is a test/homework, I'll give you a hint.
A triangle always is 180 degrees. If you add up all the sides, it should be 180.
A horizontal line is 180, if you add up the two sides (or the "line" that is crossing through the horizontal one) it'll be 180.
Just think of it like this: 180 is king. No matter what you add together, if its not 180, its wrong.
Hope this helps!
Hi there
Root=0.5 means x=0.5
Plug in 0.5 for x
(b-5)0.5^2-(b-2)0.5+b=0
(b-5)0.25-(b-2)035+b=0
Simplify
0.75b-2.25=0
b=3
Hope this helps
