For the series:
- 5 + ( - 1 ) + 3 + 7 + 11
common difference between the numbers is 4 and a 1 = -5
The series in sigma notation:
4
∑ ( 4 i - 5 )
i =0
If the proportion of people afraid to fly is 0.10 that means that there is a 10% chance they are afraid to fly. Though the proportion is this way, proportions aren't always exact, but are just estimations, so the proportion hasn't necessarily changed.
The correct answer is C. neither congruent nor similar.
Given that △ABC is transformed to △A'B'C' such that AB = A'B'.
We know that:
For triangles to be similar, all three angles must be same(AAA property) or all three sides must be in same proportion(SSS property) or two sides must be in same proportion and the included angle should be equal(SAS property).
For triangles to be congruent, all the three sides and all the three angles ,ust be exactly same.
Since △ABC and △A'B'C' have only one side equal, they are neither congruent nor similar.
Answer:
The answer is B.
Step-by-step explanation:
Please let me know if you want an explanation for why this is the answer (comment on this). A lot of people don't actually read the explanations, so I wouldn't want to waste my time. However, if you would like it I would be more than happy to type one out for you. Thanks!
