This is the concept of algebra:
y=^3sqrt(x-5) can be written as:
y=(x-5)^(1/3)
Given that y=0 at the point x=5, that is:
when x=5 then
y=(5-5)^(1/3)
y=0^(1/3)
y=0
from the above we conclude that the domain is:
{x∈ R: x≥5}
That means that the domain is all real numbers greater than or equal to 5.
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:
Sari didnt use correct factors for 40 in the equation
1/2 times 3^1 is 1/8 (rules of exponent) then 1/8 times 4/1 is 4/8
therefore the answer 1/2 after simplifying
Answer:
3/8
Step-by-step explanation:
3/4*1/2
there is 3/4 chance for the first spinner, and a 1/2 chance for the second spinner
