Answer: True
Step-by-step explanation:
This is true because the sample are randomly selected. When we say "random" it means selection is being made fairly without taking into consideration any factors such as age, sex, religion, etc. The selection is not bias in that regard as such the population has the same chance of being selected.
Triangles ABC and DEF may or may not be congruent, because the angle-angle-angle (AAA) postulate is not a criterion for congruency of any two triangles. This is because the angle-angle-angle postulate only incorporates the angles of the triangles, and the side lengths are not specified, so congruency may or may not be true for these triangles.
The answer is 1.804 hope it helps
The first one
this is random stuff to fill up the 20 character minimum
In order to figure this out you need to use
Descartes Rule. I attached a picture showing Descartes Rule. If the signs changes for when x is positive then the number of times it changes are the possible positive solution. If the sign changes when x is negative then the number of times it changes are the possible negative solutions. With that said the answer is A. View the picture I have attached for the possible + - and imaginary solutions.
Answer = A) One possible positive solution.
