Answer:
5 different triangles
Step-by-step explanation:
we know that
The number of diagonals of an n-sided polygon is given by the formula :

where
n is the number of sides
In this problem
n=5
substitute

see the attached figure to better understand the problem
The number of different triangles that can be formed by the sides of the polygon and its diagonals is equal to 5
so
Triangles
AEB
EDC
BCD
ACD
EBC
see the attached figure
To solve the problem we must know about the correlation coefficients.
<h3>What is the
correlation coefficient?</h3>
The correlation coefficient helps us to know how strong is the relation between two variables. Its value is always between +1 to -1, where, the numerical value shows how strong is the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.
- 1 indicates a strong positive relationship.
- -1 indicates a strong negative relationship.
- A result of zero indicates no relationship at all, therefore, independent variable.
The correlation coefficient -0.9847 denotes, "There is a strong negative relationship between x and y".
Given to us
- The correlation coefficient for the data is −0. 9847.
As we can see that the value of the correlation coefficient is 0.9847, therefore, it is close to 1 means the relationship is strong, while the '-' symbol denotes that the relationship is negative.
Hence, the correlation coefficient -0.9847 denotes, "There is a strong negative relationship between x and y".

Answer:
2 to 8 and 8 to -2
Step-by-step explanation:
Well, we would have to divide 7 into 20 in order to find the decimal, so 7 divided by 20 = 0.35, so 7/20 as a decimal is 0.35, and if you move the decimal two places to the left, it is also 35%.
I hope I helped! =D
Answer:
Larger angle: 104 degrees
Smaller angle: 76 degrees
Step-by-step explanation:
(9x+5) + (6x+10) = 180
x = 11
