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.
Answer:
20 units
Step-by-step explanation:
The Pythagorean Theorem states that:
Now we can insert values into the equation.
Now we can plug these ☝ values into the Pythagorean Theorem:
After we solve for we get:
