Which parts of this excerpt from Beowulf denote the importance of kinship and lineage? I have been strand-guard, standing as warden, Lest enemies ever anywise ravage Danish dominions with army of war-ships. More boldly never have warriors ventured Hither to come; of kinsmen’s approval, Word-leave of warriors, I ween that ye surely Nothing have known. Never a greater one Of earls o’er the earth have I had a sight of Than is one of your number, a hero in armor; No low-ranking fellow adorned with his weapons, But launching them little, unless looks are deceiving, And striking appearance. Ere ye pass on your journey As treacherous spies to the land of the Scyldings And farther fare, I fully must know now What race ye belong to. Ye far-away dwellers, Sea-faring sailors, my simple opinion Hear ye and hearken: haste is most fitting Plainly to tell me what place ye are come from.” Show more >

Hither to come; of kinsmen’s approval,

Word-leave of warriors, I ween that ye surely

Nothing have known. Never a greater one

Of earls o’er the earth have I had a sight of

Than is one of your number, a hero in armor;

No low-ranking fellow adorned with his weapons,

But launching them little, unless looks are deceiving,

And striking appearance. Ere ye pass on your journey

As treacherous spies to the land of the Scyldings

And farther fare, I fully must know now

What race ye belong to. Ye far-away dwellers,

Sea-faring sailors, my simple opinion

Hear ye and hearken: haste is most fitting

Plainly to tell me what place ye are come from.”

A relief airplane is delivering a food package to a group of people stranded on a very small island. The island is too small for the plane to land on, and the only way to deliver the package is by dropping it. The airplane flies horizontally with constant speed of 220 at an altitude of 550 . The positive x and y directions are defined in the figure. For all parts, assume that the “island” refers to the point at a distance from the point at which the package is released, as shown in the figure. Ignore the height of this point above sea level. Assume that the acceleration due to gravity is = 9.80 .

An experimenter wants to know if a particular molecule is effective at reducing inflammation. The experimenter treats patients with 10 different types of inflammations. For the 10 conditions the experimenter obtains the following p-values: p1 = 0:04; p2 = 0:36; p3 = 0:06; p4 = 0:015; p5 = 0:09 p6 = 0:0066; p7 = 0:0055; p8 = 0:02; p9 = 0:12; p10 = 0:008 Based on these p-values, would it be correct for the researcher to claim that she has significant data to support the effectiveness of the molecule ? If the answer is no, how would you interpret the result and what would you suggest to the researcher.
