Students were measuring distances and found one to be 2.04 m. When they asked the teacher if their measurement was correct, the teacher said, “Actually, it is 2.16 m.” What is the percent error?

Answers

Answer:

The percentage error is 5.56%

Explanation:

Given

[tex]Measured (M) = 2.04m[/tex]

[tex]Actual (A)= 2.16m[/tex]

Required

Determine the percentage error

Percentage error (P) is calculated as follows:

[tex]P = \frac{|A - M|}{A} * 100\%[/tex]

[tex]P = \frac{|2.16 - 2.04|}{2.16} * 100\%[/tex]

[tex]P = \frac{|0.12|}{2.16} * 100\%[/tex]

[tex]P = \frac{0.12}{2.16} * 100\%[/tex]

[tex]P = \frac{12\%}{2.16}[/tex]

[tex]P = 5.56\%[/tex]

Hence:

The percentage error is 5.56%

The correct answer is B. Participants who drop out during the course of the study may be different in important ways from ones who did not drop out.

Explanation:

In longitudinal studies, the same population or participants are studied for a long time, usually multiple years. This method helps the researcher to get meaningful results about participants' ideas, behaviors, etc. and how these change over time.

However, this type of study has also disadvantages, one of these is that participants are more likely to drop out because it requires more time than participating in regular studies. Moreover, this can cause important information to be omitted as those participants who drop out might offer data that is important and unique. According to this, the correct answer is B.

Briefly describe ONE similarity between the British-Native American relations described in the petition and French-Native American relations.

Answers

Answer:

Both the British and the French saw Native Americans as an essential factor in the success or defeat of their settlements.

Explanation:

There are few similarities between the relations between British and Native Americans and French and Native Americans, but we can say that a similarity in that relationship was the fact that both European groups saw Native Americans as a key element for success imperialist and colonial.

The British saw the natives as a competition for space and as pagan, savage and uncivilized beings and for this reason, they decided that it would be better to suppress the natives, expel them from their lands and even enslave them, in favor of the British crown.

The French, on the other hand, established many economic partnerships with the Indians and did not see them as a competition, but as a way of tracing the work, which gave the friars privileges on the commercial routes.


Task: The First National Bank of Minnetonka, Minnesota, was robbed of $1,000,000.



The robbery was discovered at 8:00 a.m. on Friday, November 12. The bank had closed at 5:00 p.m. the previous day.

Miss Margaret Ellington, a teller at the bank, discovered the robbery. The vault of the bank had been blasted open by dynamite.

The president of the bank, Mr. Albert Greenbags, left before the robbery was discovered. He was arrested by authorities at the Mexico City airport at noon on Friday, November 12.

The president of the bank had been having trouble with his wife, who spent all of his money. He had frequently talked of leaving her.

The front door of the bank had been opened with a key.

The only keys to the bank were held by the janitor and the president of the bank.

Miss Ellington often borrowed the president's key to open the bank early when she had an extra amount of work to do.

A strange, hippie-type person had been hanging around the bank on Thursday, November 11, watching employees and customers.

A substantial amount of dynamite had been stolen from the Acme Construction Company on Wednesday, November 10.

An Acme employee, Howard Ellington, said that a hippie had been hanging around the construction company on Wednesday afternoon.

The hippie-type character, whose name was Dirsey Flowers and who had recently dropped out of Southwest Arkansas State Teachers College, was found by police in East Birdwatch, about ten miles from Minnetonka.

Dirsey Flowers was carrying $500 when police apprehended him and had thrown a package into the river as the police approached.

Anastasia Wallflower of East Birdwatch, Wisconsin, said that she had bought $500 worth of genuine Indian love beads from Dirsey Flowers for resale in her boutique in downtown East Birdwatch.

Anastasia said that Dirsey had spent the night of November 11th at the home of her parents and left after a pleasant breakfast on the morning of the 12th.

When police tried to locate the janitor of the bank, Elwood Smith, he had apparently disappeared.

Miss Ellington stated that her brother Howard, when strolling to Taylor's Diner for coffee about 11:00 p.m. on Thursday, November 11, had seen Mr. Smith running from the bank.

Mr. Smith was found by the FBI in Dogwalk, Georgia, on November 12. He had arrived there via Southern Airlines Flight 414 at 5:00 p.m.

The airline clerk confirmed the time of Smith's arrival.

Mr. Greenbags was the only person who had a key to the vault.

There were no planes out of Dogwalk between 4:00 p.m. and 7:00 a.m.
In addition to keeping payroll records, Mr. Ellington was in charge of the dynamite supplies of the Acme Construction Company.

Mr. Greenbag's half-brother, Arthur Nodough, had always been jealous of his brother.

Nodough always got drunk on Friday nights. Arthur Nodough appeared in Chicago on Monday, November 8, waving a lot of money.

Arthur wanted to marry Camelia Smith.

Miss Ellington said that Smith had often flirted with her.

Mr. Smith's father, a gold prospector in Alaska, had died in September.

Mr. Greenbags waited in the terminal at O'Hare Field in Chicago for 16 hours because of engine trouble on the plane he was to take to Mexico City.

If the pond is resampled a year later, which of the following would best indicate that the pond had been adversely affected by adjacent development?

Answers

This question is not complete; here is the complete question:

A one-hectare pond is sampled in early September. The sample yields 1 small catfish as well as 17 benthic invertebrates that represent 10 species.

If the pond is resampled a year later, which of the following would best indicate that the pond had been adversely affected by adjacent development?

A. An uncommon species has become more numerous

B. An increase in low-tolerance species has occurred

C. A decrease in high-tolerance species has occurred

D. Phylogenetic diversity has occurred

E. The biodiversity of the pond has decreased

The answer to this question is E. The biodiversity of the pond has decreased

Explanation:

In ecology, an ecosystem can be affected by adjacent developments including human developments or even other ecosystems and this can lead to positive or negative consequences.

In this context, one example that shows the was an adverse effect is "The biodiversity of the pond has decreased" because the reduction in diversity represents a major thread for an ecosystem as this makes species more vulnerable to disappear. Also, this can be caused by factors such as pollution caused by human development or major predator of the adjacent ecosystem feeding on organisms in the main ecosystem. Besides this, in the first sample, there were multiple species and a reduction in the second sample shows the ecosystem was weakened.

What is meditation?

Meditation is the practice of focusing one's mind for an extended period of time while observing but not engaging with thoughts.

This can be done in silence or with the help of chanting and is done for a variety of reasons, ranging from religious or spiritual purposes to relaxation.

Meditation can provide you with a sense of calm, peace, and balance, which can benefit your emotional well-being as well as your overall health. You can also use it to relieve stress and relax by refocusing your attention on something calming.

Meditation is so effective because it causes shifts in our awareness. Many people over-identify with their thoughts and emotions, which can make them feel longer and larger than they are.

Thus, the correct option is B.

Explanation:

Pythagorean Theorem: a² + b² = c²

c = hypotenuse

a, b = legs

When we are given 2 sides of a right triangle, we can use Pythagorean Theorem to find the missing side:

8² + 3² = c²

64 + 9 = c²

73 = c²

c = √73

8 squared is 64 and 3 squared is 9 so 73 = the missing side squared
Therefore the answer is the square root of 73
