I think it’s SAS
SAS Means: If any two angles and the included side are the same in both triangles, then the triangles are congruent
To find the sum of the interior angles of a heptagon, divide it up into triangles ... There are five triangles... Because the sum of the angles of each triangle is 180 degrees... We get.
(4,12) is the correct answer
Using it's concept, it is found that the sample mean package weight for Thursday is of 19 ounces.
<h3>What is the mean of a data-set?</h3>
The mean of a data-set is given by the <u>sum of the observations divided by the number of observations</u>.
For Thursday, the package weights in ounces are given by: {18, 19, 20, 19}.
Hence, the sample mean in ounces is of:
M = (18 + 19 + 20 + 19)/4 = 19.

Answer:
D) collinearity
Step-by-step explanation:
Collinearity occurs when a few of the independent variables are related or match up. Collinearity increases the large proportion the variance of an estimated regression coefficient which leads to certain regression coefficient having wrong signs. It is used to explain the relationship between two variables.
