Answer:
See explanation.
Step-by-step explanation:
First put 2x-4 equal to 0 and solve it.
2x-4=0
2x=4
x=2
Now plug 2 into the polynomial and see if it equals to 0
In case it's not, then it is not a factor of it
2(2)^5 - 4(2)^4 + 2x^2 -2(2) - 4 = 0
So it's indeed a factor of the polynomial.
Hope this helps!
Answer:
E. a contingency table
Step-by-step explanation:
First we need to identify the number of variables in the survey. The choice of graphical display depends on the number of variables and their types.
The survey was conducted to study the relationship between:
1) Whether the family is buying or renting their homes
This is a categorical variable with 2 possible options
2) Marital Status of the Parents
This is also a categorical variable with 4 possible options: Married, single, divorced, and widowed
This means, we have to display 2 categorical variables side by side, showing their relationship. To display such data we always use a contingency table.
A contingency table or a 2-way table is a type of Frequency Distribution that is used to summarize the relationship between two or more Categorical Variables. Its similar to matrix form i.e. in form of rows and columns of a table. The minimum size is 2 rows and 2 columns.
An example of the contingency table that can be drawn for a data collected in a similar survey is shown in the image below.

Answer:
The midpoint is (1,4)
Step-by-step explanation:
To find the midpoint
Add the x coordinates together and divide by 2
(x1+x2)/2 = (3+-1)/2 = 2/2 =1
Add the y coordinates together and divide by 2
(y1+y2)/2 = (6+2)/2 = 8/2 =4
The midpoint is (1,4)
