Answer:
A. The Ratio Test says that the series converges absolutely
Step-by-step explanation:
It is a term used in mathematics which means the test for series convergence in which each terms changes to a real or complex number a n is non zero when n is big. This test was produced by Jean Le Rond d' Alembert.

Answer: a) (0.755, 0.925)
Step-by-step explanation:
Let p be the population proportion of 8th graders are involved with some type of after school activity.
As per given , we have
n= 100
sample proportion:
Significance level :
Critical z-value : (using z-value table)
Then, the 98% confidence interval that estimates the proportion of them that are involved in an after school activity will be :-
i.e.
i.e.
i.e.
Hence, the 98% confidence interval that estimates the proportion of them that are involved in an after school activity : a) (0.755, 0.925)
For this case we have the following functions:
We must find . By definition we have to:
So:
Finally, the composite function is:
Answer:
Since 20 = 25 is clearly a false statement, the three side lengths 2 ft, 4 ft, and 5 ft do not form a right triangle.
