Answer:</h2>
∠LMN is a right angle
<h2>
Step-by-step explanation:</h2>
If we want to prove that two right triangles are congruent by knowing that the corresponding hypotenuses and one leg are congruent, we begin as follows:
- Since two legs are congruent and we know this by the hash marks, then the triangle ΔLKN is isosceles.
- By definition LN ≅ NK
- If ∠LMN is a right angle, then MN is the altitude of triangle ΔLKN
- Also MN is the bisector of LK, so KM ≅ ML
- So we have two right triangles ΔLMN and ΔKM having the same lengths of corresponding sides
- In conclusion, ΔLMN ≅ ΔKMN
It is 28 because you have to take the median out then go to the first set of data and find the median of that.
Answer:
The sample size is too small
Step-by-step explanation:
The answer is the last one: the sample size is too small. Since we only got 3 subjects to test, maybe one of them could live for a long time after the diagnosis of Cacer and that made the average survival time go up by a lot.
In order to obtain results with a significance level higher, you need a sample size of at least 20 subjects.
Now lets see why other options wouldnt be good answers:
- For a small amount of subjects, it is unlikely to have errors in caculation
- The sample size is given
- We are not given information about the treatment and we dont even know if the subjects feel more confident with the new treatment. Also, if a Placebo effect works regularly, it shouldnt limit statistical sifgnificance
- An increase in 2 years is huge in comparison with the previous survival time.
