How to get the sum of the first 8 terms?</h3>
In an arithmetic sequence, the difference between any two consecutive terms is a constant.
Here we know that:
There are 7 times the common difference between these two values, so if d is the common difference:
Then the sum of the first 8 terms is given by:
So we conclude that the sum of the first 8 terms of the arithmetic sequence is 17/5.

the answer is pi36 bc the formula for area is pir^2
Answer:
0
Step-by-step explanation:
Rewrite the equation as x^2-3x+9=0
find the determinant.
D = b^2-4ac = (-3)^2-4*1*9 <0
no solution
My answer would be A. Because if your line is going down, it is a negative slope. And the y-intercept is at negative 1.

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.
