I believe that this would be representative.
An obtuse triangle must have an angle greater than 90degrees (cannot equal 90). Therefore, A. would be the correct answer. This is because A. is the only set of angles that includes an angle greater than 90. Also, all angle measures add up to equal 180degrees.
Its being dilated by 3 therefore your answer is 9.9
So the modal value is most commonly known as mode, or the most common number in a data set. So the most common number in this stem-and-leaf plot is 137
The modal value is 137
Hopes this helps!
A union for sets means you combine the two sets together. The symbol of a union is ∪, so we can represent this question with K <span>∪ L.
You simply must combine the two sets together without repeating any of the same numbers.
K </span><span>∪ L = {2, 3, 5, 7, 8}.</span>
