Sir Isaac Newton is buried at Westminster Abbey in London. Which of these other famous people is most likely to also be buried t
melomori [17]

Sir Isaac Newton is buried at Westminster Abbey in London.

<u>Queen Elizabeth I</u> is most likely to also be buried there.

<h3>Who is Sir Isaac Newton?</h3>

Isaac Newton, or Sir Isaac Newton, was an English physicist and mathematician who was the pinnacle of the Scientific Revolution of the 17th century. Newton was born in Woolsthorpe, Lincolnshire, England, on December 25, 1642 (or January 4, 1643, New Style), and died in London on March 20 [or March 31, 1727].

His understanding of the nature of white light in optics helped to incorporate the color-related phenomena into the study of light and laid the groundwork for contemporary physical optics. The law of universal gravitation was developed in mechanics as a result of his three laws of motion, which are the cornerstones of contemporary physics.

Should research into expensive medical treatments be allowed when only a few can afford them?.
Hatshy [7]

Answer:

I believe everyone has the right for the access even to the most expensive medical treatments. Those who can afford to have them may be in a more advantageous stage. However, the less fortunate may still have the access through aids from different groups such as the government, and other non-governmental organizations.  Read more at Answer.Ya.Guru – https://answer-ya.com/questions/2990468-should-research-into-expensive-medical-treatments-be-allowed.html

The distribution of number of hours worked by volunteers last year at a large hospital is approximately normal with mean 80 and
Mazyrski [523]

Explanation:

Using the normal distribution, it is found that the probability that the volunteer selected will receive a certificate of merit given that the  number of hours the volunteer worked is less than 90 is closest to:

B 0.123

In a normal distribution with mean \muμ and standard deviation \sigmaσ , the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}Z=σX−μ

It measures how many standard deviations the measure is from the mean.  

After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

In this problem:

The mean is of 80, hence \mu = 80μ=80 .

The standard deviation is of 7, hence \sigma = 7σ=7 .

The minimum value is the 80th percentile, which means that it is X_mXm when Z has a p-value of 0.8.

The probability that the volunteer selected will receive a certificate of merit given that the number of hours the volunteer worked is less than 90 is P(X_m < X < 90)P(Xm<X<90) , which is the p-value of Z when X = 90 subtracted by the p-value of Z when X = X_mX=Xm , hence the p-value of Z when X = 90 subtracted by 0.8.

Z = \frac{X - \mu}{\sigma}Z=σX−μ

Z = \frac{90 - 80}{7}Z=790−80

Z = 1.43Z=1.43

Z = 1.43Z=1.43 has a p-value of 0.9236.

0.9236 - 0.8 = 0.1236, hence closest to 0.123, option B.
