The percent of the decrease in the average monthly revenue is 10%.
How to calculate the percent of the decrease?We can calculate the percent of the decrease by using the following formula:
The percent of the decrease = (previous revenue - current revenue) / previous revenue × 100%
Last year, the average monthly revenue at the Cedarburg Times newspaper was $66,490.
This year, the average monthly revenue so far has been $59,841.
The percent of the decrease = (previous revenue - current revenue) / previous revenue × 100%
previous revenue = $66,490.
current revenue = $59,841
The percent of the decrease = ($66,490 - $59,841) / $66,490 × 100%
The percent of the decrease = 6,649 / $66,490 × 100%
The percent of the decrease = 0.1 × 100%
Apply the multiplication operation, and we get
The percent of the decrease = 10%
Thus, the drop in the average monthly revenue is 10%.

(a) describe a procedure for identifying potential outliers, and use the procedure to decide whether there are outliers among the responses for the money spent on textbooks. (b) based on the stemplot, write a few sentences describing the distribution of money spent on textbooks for the 34 students.
a) A procedure for identifying outliers is identifying if there are values that are more than 1.5 IQR from the quartiles. Thus, the value of 810 is an outlier in the given distribution.
b) As the distribution contains a high outlier, it means that the distribution is right skewed.
How to identify the outliers?The first quartile of a data-set is the element that represents the 25th percentile of the distribution.
For a distribution of 34 students, the first half of the distribution has 16 values, hence the first quartile is the mean of the 8th and 9th values.
From the stemplot, these values are 170 and 180, hence:
Q1 = (170 + 180)/2 = 175.
The third quartile is the 75th percentile of the distribution, hence it is the mean of the 8th and 9th values of the second half of the distribution.
From the stemplot, these values are 39 and 41, hence:
Q3 = (390 + 410)/2 = 400.
The IQR is the difference between the quartiles, hence:
IQR = Q3 - Q1 = 400 - 175 = 225.
Values that are more than 1.5 IQR from the quartiles are considered outliers, hence the bounds are given as follows:
Lower outliers: less than 175 - 1.5 x 225 -> there are no lower outliers.High outliers: higher than 400 + 1.5 x 225 = 737.5.Hence the value of 810 is a high outlier. This high outlier will influence the mean, making it higher than the median, and thus the distribution is right skewed.
Missing InformationThe stemplot is given by the image shown at the end of the answer.

How do I write an algebraic expression?
An equation is like a sentence, just using a different language. Mathematical equations are telling you to do something, giving you information on how to respond, or come up with an answer. It's up to you to learn this language. However, once you know it, you can write in this language.
A mathematical equation, also known as a statement, shows that two separate expressions are equal. The two expressions are usually connected by the "equal-to" (=) sign. You can find the expressions in a mathematical statement by looking at the left-hand side and the right-hand side of the equation, using the = sign as the point of reference.
The most popular equations are algebraic equations or expressions, in which letters are used as variables. Variables are placeholders that can assume any value. They can also be referred to as unknowns. You must solve for the correct value of the variable to make the equation true.
Let us look at an example to understand.
4x + 2x = 12
The letter x is the variable. You must find the value of x. Finding this value will make the right-hand side of the equation equal to the left-hand side. Let's solve this together.
In this case, since both variables are the same, you can add the values on the left-hand side.
6x = 12
Now, we divide both sides by the value of '6', which will help us solve for x. Consider this to be a way to unravel the equation. Also, remember that whatever is done to one side must be done to the other.
x = 2
This is exactly how to write an algebraic expression.

How do you read a limit on a graph?
The limit of a graph can be read by a function is said to have a limit if the value of the function is less than or equal to a particular value.
Limit
One way to think about the limit of a function at a number at x = an is as the value that the function begins to take as it gets closer to that value. Approaching the location where x = a can be done from either the left or the right side.
From a limx to a f (x)
As an illustration, if f(x) is defined as the limit of x, then x is the highest value that f can take. A function is said to have a limit if the value of the function is less than or equal to a particular value.

The interest on Ethan's CD account will be $700 * 1.8% = 12.6$ dollars after one year. Since the CD earns 1.8% interest each year, the interest will be the same amount each year, so the total interest on the CD after 6 years will be $12.6 * 6 = 75.6$ dollars.

How do you make the discontinuous classes as continuous classes explain with an example?
Discontinuous classes can be made continuous by using interpolation, which expression values between known points. For example, a discontinuous class of heights can be made continuous by using interpolation to estimate heights between known points.
Discontinuous classes can be made continuous by using interpolation. Interpolation is a mathematical process that estimates values between known points. This can be done in a variety of ways, such as linear interpolation which estimates values using the slope between two known points, or polynomial interpolation which uses a polynomial equation to estimate the values between known points. For example, if you have a discontinuous class of heights, you can use interpolation to estimate values between the known heights. This would result in a continuous class of heights, which may be more useful than the discontinuous class. Interpolation can also be used to estimate other types of values, such as temperature, pressure, or any other type of value that can be represented on a continuous scale.

What are the slope and Y − intercept of the equation y 2x − 4 *?
The equation in slope-intercept form as y = 2x - 4, where 2 is the slope and -4 is the y-intercept.
The equation y = 2x - 4 can be written in slope-intercept form as y = 2x + b, where b is the y-intercept. To find the slope and y-intercept of the equation, we need to solve for b.
The y-intercept is the point where the line crosses the y-axis. To find the y-intercept, we can set x equal to 0 in the equation to get y = 2(0) - 4. This simplifies to y = -4, so the y-intercept is -4.
The slope is the rate at which the line rises. To find the slope, we can take the coefficient of x, which is 2. So the slope of the equation y = 2x - 4 is 2.
In summary, the slope of the equation y = 2x - 4 is 2 and the y-intercept is -4. We can write the equation in slope-intercept form as y = 2x - 4, where 2 is the slope and -4 is the y-intercept.
