How can i graph the equation using the slope and the y intercept y=7/4x+2
Lelu [443]

Since you already have the equation, all you need to do is pick two values of x.

For example, when x = 0, you get y = 7/4(0) + 2 = 2. So the line passes through the point (0, 2). When x = 4 (picked to cancel the 4 in the fraction), you get y = 7/4(4) + 2 = 9, so the line also passes through the point (4, 9).

You can describe an entire line by any two points that it contains. So plot these two points, then connect the dots with a line passing through them both.

Of the 10,000 clocks from which the sample was chosen, about how many clocks are probably not defective?
tamaranim1 [39]

The number of clocks that are not defective is an illustration of proportions

Of the 10000 clocks, 9250 are probably not defective

<h3>How to determine the number of clocks that are not defective?</h3>

From the complete question, we have the following parameter:

15 out of 200 clocks are defective

The above means that the number of clocks that are not defective is:

Not defective = 200 - 15

Not defective = 185

Express as percentage

Not defective = 185/200

Not defective = 92.5%

In 10,000 the number of clocks that are not defective would be:

Not defective = 92.5% * 10000

Not defective = 9250

Hence, 9250 of the 10000 clocks are probably not defective

Read the quotation from Lincoln Steffens’s The Shame of the Cities. "My purpose was...the see if the shameful facts, spread out
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
