Use a statistics calculator to find the area, in decimal form, rounded to four places after the decimal, under the (standard) No

Jlenok [28]

Answer:

a) 0.9641.

b) 0.0082

c) 0.0277

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score 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. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

(a) ...to the left of 1.8.

p-value of Z = 1.8, which, looking at the z-table, is of 0.9641.

(b) ...to the right of 2.4.

1 subtracted by the p-value of Z = 2.4.

Looking at the z-table, Z = 2.4 has a p-value of 0.9918.

1 - 0.9918 = 0.0082, which is the answer.

(c) ...between 1.8 and 2.4.

p-value of Z = 2.4 subtracted by the p-value of Z = 1.8.

From itens a and b, we have both. So

0.9918 - 0.9641 = 0.0277

In the quotation in lines 61-64, George Will

nexus9112 [7]

The correct answer is option e) the extent to which a cloned person might differ from the original person.

In the quotation in lines 61-64, George Will primarily draws attention to the extent to which a cloned person might differ from the original person.

What is human(person) cloning?

Human cloning is the process of creating a genetically identical replica of a human (or clone).

The phrase is most commonly used to refer to artificial human cloning, or the replication of human cells and tissue. It does not relate to identical twins being conceived and delivered naturally.

The prospect of human cloning has sparked debate. Because of these ethical considerations, numerous countries have passed laws prohibiting human cloning.

Therapeutic cloning and reproductive cloning are the two most widely discussed kinds of human cloning. Therapeutic cloning would include cloning human cells for use in medicine and transplantation.

Context of lines 61-64

Satan is disoriented in a completely black pool of fire. Beelzebub, Satan's second-in-command, stands next to him. Satan addresses him and laments their current situation.

Satan advises them to flee the flaming lake and seek refuge on a distant beach. Beelzebub requests that Satan assemble his soldiers. Satan dons his armor and summons his armies to join him on land.

He addresses his troops and vows to continue his battle against God. The demons use their superhuman abilities to build Pandemonium, a huge temple for meetings.

EXPLANATION

The poet depicts the classic landscape of Hell in these verses. After their rebellion against God, Satan and his minions were hurled down from Heaven to Hell.

For nine days, they lay comatose in Hell's burning lake. When they regain consciousness, Satan notices that the location in which they are imprisoned is a horrifying, circular, and burning dungeon like a large furnace.

This analogy vividly conjures up the image of Hell's lake. Satan notes that there is fire but no light in Hell; it is complete darkness, complete darkness, without any residue, mixture, or prospect of light.

It will always be the blackness of darkness. The poet here employs the universal symbolism of light and dark to represent good and evil.

Satan, as Lucifer, was the brightest of all the angels before his fall; as he grows progressively more evil after his fall, he eventually loses all of his brightness.

Satan comes to the conclusion that the fires will never go out and the pain will never cease. In essence, the poet's description of Hell in these verses is a horrifying, scorching, and murky realm of sorrow and pain.
