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.
Use PEMDAS. Parenthesis, Exponents, Multiply, Divide, Addition, Subtraction.
So, you'd distribute 5 into the parenthesis, leaving you with 9+20x+20, then add like terms. 20x+29
Answer:
875
Step-by-step explanation:
If there are 100 tagged rabbits and which there are 40 tagged out of 350 we get
The amount tagged/ The amount of rabbits = Tagged come back/Caught
If we replace the equations we get the equation
100/x = 40/350
Step 1. Cross Multiply
40x = 35000
x = 875
There are 875 rabbits
Answer:
268
cause 20 % off of each then added = 268
