Answer:
Spring constant, K = 415.9 N/m
Explanation:
The period of vibration of a spring, T, is given by:
T = 2√m/K
Where m = mass of the body in kg, K = spring constant or force constant or elastic constant or stiffness in Nm-1
Making K the subject of the expression,
K = m(2)2/(T)2
K = 4m()2/(T)2
Where m = 0.38kg, = 3.14285714286, T = 0.19s
K = 4 x 0.38 (3.14285714286)2 / (0.19)2
K = 4 x 0.38 x 9.87755102043 / 0.0361
K = 15.0138775511 / 0.0361
K = 415.9 Nm-1

Answer:
The best answer to the question: Which quotation correctly uses ellipsis to shorten Twain´s words, would be: the second one "and there is no reason why I shouldn´t".
Explanation:
The reason for this being the correct answer comes from understanding the purpose of an ellipsis, or ellipses. Ellipses are punctuation marks, just like comas, or periods, that have the specific purpose of marking portions of a written sentence, paragraph, passage, or an entire text, that are not really needed information, but rather added, and which if removed from the text will not affect the overall comprehension of the meaning of the text. In this case, Twain saying "and there is no reason why I shouldn´t" in regards to how long he expects to live, is added information to the main passage that if removed from it will not affect the overall understanding of his meaning.
Answer: The confidence interval would be (82198.71, 103801.28).
Explanation:
Since we have given that
Mean = $93,000
Standard deviation = $17,000
n = 12 < 30
So, we will use 't-test' to find the 95% confidence interval,
Here , 
and 
So, according to t table, we get that

So, interval would be

Hence, the confidence interval would be (82198.71, 103801.28).
Answer:
true
Explanation:
The largest animal phylum is also included within invertebrates: the Arthropoda, including insects, spiders, crabs, and their kin. All these organisms have a body divided into repeating segments, typically with paired appendages. ... Other invertebrates include the Nemertea or ribbon worms, and the Sipuncula.
