<h3>Answer: D) y+3</h3>
==========================================================
Explanation:
Point A is located at (3,1). Point A' is located at (-5,4)
To move from A to A', we'll do two things:
- Move 8 units to the left
- Move 3 units up
The "8 units to the left" portion has us go from x to x-8
The "3 units up" part involves y becoming y+3
So that's how we get the translation rule . The x-8 portion is already filled in for us. The missing part is y+3 which is the final answer (choice D).
Let's try this translation rule on point B to see if we arrive at the proper location of B'
B is at (2,6) which means
which matches up what the diagram shows. I'll let you verify that the rule also works for point C.
Answer:
(A) A scatter plot is used to determine if the linear model is appropriate.
(B) A linear model estimates the value of the dependent variables.
Step-by-step explanation:
The regression model is formed to estimate the Wingspan using the bird's Height when perched.
The model is of the form:
(A)
The <em>R</em> squared value is a statistic that is used to determine the proportion of variation in the dependent variable that can be explained by the independent variables.
<em>R</em> squared value of 93% indicates that 93% variation in the Wingspan is explained y the bird's height when perched.
To determine whether the linear model is appropriate one could use a scatter plot. A scatter plot is used to determine whether the provided data is representing the linear relation between two variables.
(B)
The regression model is:
This model is used to estimate the wingspan for any provided bird's height.
It does provided an accurate value of the dependent variable.
Thus, a bird with height 10 inches can have an estimated wingspan of 17 inches.
