Answer:

About 13 hard drives

Explanation:

Using the rule of three, if studying the access speed of 40 hard drives gives the maximum estimate error of 15, then we multiply 5 (which is the number of estimates that are sought in a second attempt) by 40 hard drives divided by 15 as maximum estimate number. We get a total of 13.33,<em> therefore we would need an approximate of 13 hard drives to reduce the maximum estimation error to 5.</em>

  40 hard drives   ---- 15  

13.33 hard drives ---- 5

(40 * 5) / 15 = 13.33 hard drives

Phratry is an unilineal descent kinship group composed of at least two clans that supposedly share a common ancestry

More about phratry:

The Greek word for "phratry" means "his brother." Around the second century BC, at the beginning of the human era, there was a divide of Greek tribes known as the Phratry. Their relationship was one of brotherhood and shared kinship. People from the same caste, for instance, could fall into this group under the current circumstances.

Phratry supremacy was observed during the Dark Ages, but it declined in importance during the Classical era. Due to this age, other influential groups, such as political parties and churches, are forming. Political party supremacy is still evident everywhere today.

Which statement best describes the context of this excerpt?
laila [671]

Answer:

Light-rail systems have been tried all over the country, and they've failed. The system the city proposes won't work, either. People enjoy their cars too much to endure inconvenience for the sake of the environment. And I don't blame them. As the owner of Jake's Used Cars and Trucks, I have seen the joy and freedom car ownership brings people. Americans will never abandon that feeling for the sake of being slightly better citizens. I believe it is far more responsible to purchase a high-quality car with good fuel efficiency. Building an entire light-rail system will be wasteful if few people use it — plus, it will take years to build and cost taxpayers millions of dollars. I encourage all city residents to vote against the light-rail system on May 1.
