employee worked each week for seven consecutive weeks were 38, 37. 5, 38. 25, 35. 75, 39. 5, 39. 5, and 38. 5.

What, approximately, is the mean number of hours this employee worked each week for the seven weeks?

O 37. 63

O 37. 92

O 38. 14

O 38. 25

39. 5

Answers

Answer:C. 38.14

Step-by-step explanation:

The required mean of the given data is given as the employee worked 38.14 hours through 7 weeks.

Given that,
The number of hours the employee worked each week for seven consecutive weeks was 38, 37. 5, 38. 25, 35. 75, 39. 5, 39. 5, and 38. 5.

What is mean?

The mean of the values is the ratio of the total sum of values to the number of values.

here,
According to the question,
Mean = Sum of the working hours/number of weeks
Mean = 38 + 37. 5 + 38. 25 + 35. 75 + 39. 5 + 39. 5 + 38. 5 / 7
Mean = 267/7
Mean = 38.14

Thus, the required mean of the given data is given as the employee worked 38.14 hours through 7 weeks.

Find the measure of the exterior ∠1.
A. 60°

C. 150°
D. 90°

Answers

[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]

Measure of an exterior Angle of a triangle is sum of two opposite interior angles of the same triangle ~

that is :

[tex]\qquad \tt \dashrightarrow \: \angle1 = 60 + 30[/tex]

[tex]\qquad \tt \dashrightarrow \: \angle1 = 90 \degree[/tex]

So, D is the correct choice ~

Step-by-step explanation:

As the sum of all angles of triangle is 180°

and we have been given 2 angles i.e 30° and 60°

So, Third angle will be 90°

Angle 1 = 180°-90° (as the value of angle made by a straight line is 180°)

Angle 1 = 90°

Answer:

BC ≈ 18.7

Step-by-step explanation:

using the sine rule in Δ ABC

Please hurry 50 pointsRead this excerpt from "Mad Cow, Furious Farmer.The disease was first detected in England in 1986, though some scientists think the very first cases started at least ten years before. Cows usually eat only grass and other plants, but farmers had been feeding them a meat and bone mixture that made the cows plumper. But somehow, at least one batch of the mixture had become contaminated with what was then an unknown killer: a prion.By 1993, British farmers were reporting up to one thousand new cases of BSE a week. Governments all around the world reacted by increasing testing for the disease and not allowing any cows to be eaten if they were at risk of having the disease. As sheep can also get a prion disease called scrapie, they were tested as well. Farmers were angry that they were losing their livestock, and nobody knew how to protect cows and people from the disease.Consumers were also in a panic when they learned about BSE, and for a very good reason: prions are infectious. If you eat a prion from a "mad cow or sheep, you are at risk for developing a human version of BSE. The public felt betrayed that their governments had underreacted to the problem or covered it up.Eventually, in 1997, governments began to ban farmers from feeding their livestock high-risk meat and bone mixtures. With that ban, the epidemic quickly peaked, and by 2010 had largely disappeared. Over the years, half a million cows and two hundred people had been killed by prions.What is the main idea of this excerpt?Mad cow disease ended because of government bans on feeding cows certain foods, but people were angry that governments did not act sooner.Mad cow disease was originally caused when governments allowed for cows food sources to be contaminated, so people were angry at their leaders.Both farmers and customers had been aware of mad cow disease, but they did not think their governments should have done anything to stop it.Both farmers and customers protested to prevent their governments from interfering with the farming and selling of cows and meat.
