a data analyst creates a scatterplot with a lot of data points. the analyst wants to make some points on the plot more transparent than others. what aesthetic should the analyst use?

Answers

Answer 1

Analyzers should use the Alpha aesthetic.

Using the Alpha aesthetic, specific points on a scatterplot are more transparent than others to highlight specific data points.

What is a scatterplot?

A scatter plot is a set of points plotted along a horizontal and vertical axis. In statistics (also known as variables), scatter plots are crucial to demonstrating whether a correlation exists between observational quantities or phenomena.

A scatter plot  plots data points on a horizontal and vertical axis to demonstrate one variable's influence on another. Each row in the data table is represented by a marker whose position is determined by the values of the columns on the X and Y axes.

Using a scatter plot, this line indicates the prevailing direction of a phenomenon. In a scatter plot, a trend line can be used to highlight the direction and speed of price changes.

The area of a rectangle is given as 90 cm² and the length is 3 cm longer than its width. Find the length and the width of the rectangle.

Answers

Answer:

Step-by-step explanation:

Area of a rectangle is given by the formula :

A = L × W

Substituting 90 with A , x with W and (x+3) with L, we get :

90 = (x+3)×x

Simplifying the right side by expanding the bracket :

x(x+3) =

x²+3x
90=x²+3x

Now we can make a quadratic by subtracting both sides by 90 :

x²+3x-90 =0

DUE TOMORROW PLS HELP!!

does anyone know how to solve the area and perimeter for this parallelogram pls help!!! In details !!!


Answers

Answer:

The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The area is a measurement of the surface of a shape. for example

You are able to find the perimeter of the rectangle by adding length and width and multiplying by two because the opposite sides of a rectangle are equal in length. Both lengths of the rectangle are the same, and both widths are the same. For example, P = 2 * (14 + 8) = 2 * (22) = 44 centimeter (17.3 in).

y intercept = (0, 3/7)

Step-by-step explanation:

Answers:
x intercept is -3/4, y intercept is 3/7

Step by step

To find x and y intercepts in a standard form, substitute 0 in for the other variable and solve.

-4x + 7y = 3
Solve for x

-4x + (7)(0) = 3

Divide both sides by -4 to solve for x

-4/-4 x = 3 /-4
x = -3/4

-4x + 7y = 3
Solve for y

(-4)(0) + 7y = 3

Divide both sides by 7 to solve for y

7/7 y = 3/7

y = 3/7

The possible dimension of the triangular garden assuming it to be a right-angle triangle is (12,2),(8,3), and (4,6).

What is a triangle?

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The area of a triangle is given as (1/2) × base × height.

The given area of the triangle = 12 feet².

Thus,

12 =  (1/2) × base × height

Base × height = 12 × 2

Base × height = 24

The combination of two quantities gives 24 by multiplying will be (12,2),(8,3), and (4,6).

Answers

With a net change of +0.72 yesterday's closing price was 19.81 and stock dividend yield for yesterday's closing price is 7.2%.

How to calculate the Dividend Yield?

To calculate dividend yield, all you have to do is divide the annual dividends paid per share by the price per share.

Dividend Yield = Annual Dividends Paid Per Share / Price Per Share

According to the given question:

Net change = today's price - yesterday's price

0.72 = 19.09 - yesterday's price

∴ Yesterday's price = 19.81

Stock dividend yield

Answers

64 is the standard deviation and the width of the confidence interval are both doubled .

What is standard deviation in math?

Your dataset's average level of variability is represented by the standard deviation. It reveals, on average, how far away from the mean each value is. A low standard deviation denotes that values are grouped close to the mean, whereas a large standard deviation shows that values are often far from the mean.

Margin of error(E)=0.5

Standard deviation(σ)=1.55

Significance level(α)=100%-99%=1% or 0.01

From Z distribution Critical value table

the Critical value(Zc)=2.58 at significance level=0.01

we know formula for the Margin of error

The average rate of change of function [tex]g(x)=5(2)^{x}[/tex] from x = 3 to x = 4 is 4 times that from x = 1 to x = 2.

The correct option is (A).

What is the average rate of change of a function?

The average rate at which one quantity changes in relation to another's change is referred to as the average rate of change function.

Using function notation, we can define the Average Rate of Change of a function f from a to b as:

                                     [tex]rate(m) = \frac{f(b)-f(a)}{b-a}[/tex]

The given function is  [tex]g(x) = 5(2)^{x}[/tex],

Now calculating the average rate of change of function from x = 1 to x = 2.

                               [tex]m = \frac{g(b)-g(a)}{b-a}\\ m = \frac{g(2)-g(1)}{2-1}\\\\m=\frac{5(2)^{2}-5(2)^1}{2-1}\\ m=\frac{10}{1} \\m=10[/tex]

Now, calculate the average rate of change of function from x = 3 to x = 4.

                                 [tex]m = \frac{g(b)-g(a)}{b-a}\\ m = \frac{g(4)-g(3)}{4-3}\\\\m=\frac{5(2)^{4}-5(2)^3}{4-3}\\ m=\frac{40}{1} \\m=40[/tex]

The jump from m = 10 to m = 40 is "times 4".

So option (A) is correct.

Hence, The average rate of change of function [tex]g(x)=5(2)^{x}[/tex] from x = 3 to x = 4 is 4 times that from x = 1 to x = 2.
