Step-by-step explanation:
We need to understand what residual plot is?
A residual plot is a graph that shows the residuals on the vertical axis and the independent variable on the horizontal axis.
Hence, there are 2 cases related to the relation between residual plot and a linear model:
1. If the points in a residual plot are randomly dispersed around the horizontal axis => the linear model is an appropriate fit for the data
2. If the points in a residual plot has a pattern => nonlinear model is more appropriate or the line have a bad fit with the set of the data.
Hope it will find you well.
I cannot see the numbers but i am guessing it is 2 since its in the negative region
Answer:
a) Interpretation of the expression
b)
Step-by-step explanation:
We are given the following in the question:
Unit cost of goby fish = $15
Unit cost of shrimp = $10
There are equal number of goby fish and shrimp in a bag.
A) The cost per bag with the expression
Interpretation:
The above expression represents the total cost of bag contain x number of goby fish and x number of shrimp where 15$ and 10$ are the unit cost of goby fish and shrimp respectively.
B) Expression for total cost
where C(x) is the total cost and x is the number of goby fish or the number of shrimps that are equal.

Answer:
See explanation
Step-by-step explanation:
Given
Required
The length of PQ
means that the side lengths of LMN are multiplied by 1.25 to get the side lengths of PQR
And it implies that the following sides are corresponding
So, we have:
