Answer:
There needs to be more information. We at least need to know what one of the side measurements for each triangle are. Only then can we give you the answer.
Step-by-step explanation:
The Correct answer is 4/10 And 2/10.
Or you can go with 1/5
Choice A is a trinomial, but it doesn't have a constant term
Choice D is the only other trinomial. This has a constant term, which is 6. The constant is the term without any variables attached to it.
Answer: Choice D
Answer:
8.3 < σ < 16.2
Step-by-step explanation:
The population variation can be estimated between:
(n−1) s² / χ²α/2 < σ² < (n−1) s² / χ²(1−α/2)
At 90% confidence and 13 degrees of freedom, χ²α/2 = 22.4 and χ²(1−α/2) = 5.89.
(14−1) 10.9² / 22.4 < σ² < (14−1) 10.9² / 5.89
69.0 < σ² < 262.2
8.3 < σ < 16.2
