hram777 [196]

The best description of Steffens' purpose in writing about government is:

<u>B. to describe corruption in city and state governments</u>

<u />

According to the quotation from Lincoln Steffen's The Shame of the Cities, we are told that the author feels that the shamelessness of the American people would cause the downfall of the "American pride".

As a result of this, the most likely purpose of writing this is to show the level of corruption which is prevalent in the city and state governments to spur the citizens to revolt against the corruption.

Therefore, the correct answer is option B

The professor informs the class that there will be a test next week. what is the probability that a randomly selected student st

marusya05 [52]

The probability that students who were randomly selected studied for the test, if they pass it with a B or higher grade is: D. 0.80.

<h3>How to calculate the probability?</h3>

In this exercise, you're required to determine the probability that students who were randomly selected studied for the test, if they pass it with a B or higher grade. Thus, we would apply Bayes's theorem.

Let S represent studied for.

Let B represent a score of B or higher grade

Therefore, we need to find P(S|B):

$S|B = \frac{B|S \times S}{B|S \times S\; +\; B|S' \times S'} \\\\S|B = \frac{0.55 \times 0.6}{0.55 \times 0.6 \;+ \;0.2 \times 0.4}\\\\S|B =\frac{0.33}{0.33 + 0.08} \\\\S|B =\frac{0.33}{0.41}$

S|B = 0.80.

<u>Complete Question:</u>

At the beginning of the semester, a professor tells students that if they study for the tests, then there is a 55% chance they will get a B or higher on the tests. If they do not study, there is a 20% chance that they will get a B or higher on the tests. The professor knows from prior surveys that 60% of students study for the tests. The probabilities are displayed in the tree diagram.

A beam of white light goes from air into the water droplet at an incidence angle of 36.2 degrees. what is the angle between the

torisob [31]

A beam of white light goes from air into the water droplet at an incidence angle. The angle between the red (660 nm) and violet (410 nm) parts of the refracted light is 0.19°.

<h3>What is white light?</h3>

The white light is the ray coming directly from the Sun. When it strikes any glass object, an spectrum of colors with different wavelength is formed.

Given is the angle of incidence, i = 36.2°, the refractive index of water for red light is 1.331 , the refractive index of water for violet light is 1.340 and refractive index of air is 1.

Using the Snell's law, the angle of refraction of red light will be

1.331 x sin r(R) = 1 x sin 36.2

r(R) = 26.342°

Using the Snell's law, the angle of refraction of violet light will be

1.340 x sin r(R) = 1 x sin 36.2

r (V) = 26.152°

Difference in the angle of refraction of red and violet light is

r(R) - r (V) = 26.342 - 26.152 = 0.19°

Thus, the angle between the red (660 nm) and violet (410 nm) parts of the refracted light is 0.19°.
