Why is it called line graph?
It is formed by simply drawing lines connecting the data points. Also called linear chart.
A line chart is a graphical representation of changes that occur over a period of time. A line chart has a horizontal axis called the x-axis and a vertical axis called the y-axis. The x-axis usually has a period of time over which we want to measure the quantity of a particular thing or item on the y-axis. Line charts are useful for analyzing trends, whether the quantity on the y-axis is increasing or decreasing over time. A line chart clearly shows an uptrend or a downtrend.
The line chart above represents bike sales by bike company from January to June, with the x-axis representing the time interval and the y-axis representing the number of bikes sold per month. Black dots in the graph indicate data points. A data point in a line chart represents the magnitude or number corresponding to a specific time on the x-axis. In this example, 50 bikes were sold in January. 30 bikes were also sold in February. This data can be interpreted by month using data points. Line segments connecting these individual data points show whether bike sales are trending upwards or downwards.
The key points of line charts are:
A line chart is a chart used to show changes over time as a series of data points connected by straight line segments on two axes.Line charts are also called linear chartsThis helps determine the relationship between two value sets where one data set always depends on the other.Helps show information about factors and patterns. Line charts can create expectations about outcomes for information that has not yet been obtained.In this case, the slope of the line is the most important observation. Slope indicates the slope of the line. Useful for comparing the magnitude of change between two consecutive points on the graph. For example, the steeper the slope, the greater the change in size between two consecutive points.Learn more about Linear chart:

⭐To find the distance between two points, you can use the distance formula: [tex]d = \sqrt{(x_2-x_1)^2 +(y_2 - y_1)^2}[/tex], where:
d = the distance[tex](x_1, y_1)[/tex] is one coordinate you want to find the distance from[tex](x_2, y_2)[/tex] is another coordinate you want to find the distance fromFirst, identify the coordinates you need to find the distance between, and label one coordinate as [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex].
A(-1,2) = [tex](x_1, y_1)[/tex] = (-1,2)B(1,-2) = [tex](x_2, y_2)[/tex] = (1,-2)Next, substitute [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] into the distance formula.
[tex]d = \sqrt{(1-(-1))^2+(-2-2)^2}[/tex]
[tex]d = \sqrt{(1+1)^2+(-4)^2}[/tex]
[tex]d = \sqrt{2^2+(-4)^2}[/tex]
[tex]d = \sqrt{4+16}[/tex]
[tex]d = \sqrt{20}[/tex]

g create scatterplots of the logaritms of the observed species counts versus each of the four potential explanatory variables. does the poisson regression model seem a good choice for any these explanatory veriables
it is always important to carefully evaluate the assumptions of the model and confirm that it is an appropriate fit for the data.
What is Explanatory Variables?
A researcher-manipulated variable is an explanatory variable when it comes to an experiment. It serves as a measurement of the change brought about in the response variable. A predictor variable or an independent variable are terms that are frequently used to describe an explanatory variable.
It is not possible to determine whether a Poisson regression model would be a good choice for any of the explanatory variables without further information.
To determine whether a Poisson regression model is a good fit for the data, you will need to consider the following:
The relationship between the response variable (i.e., the observed species counts) and the explanatory variables should be modeled using a linear relationship. This can be visually assessed by creating scatterplots of the logged response variable against each of the explanatory variables and examining the pattern of the points. If the points form a roughly linear pattern, then a Poisson regression model may be appropriate.
The response variable should follow a Poisson distribution. This can be assessed by examining the distribution of the logged response variable using a histogram or a Q-Q plot. If the distribution is approximately symmetrical and has a single peak, then a Poisson regression model may be appropriate.
The residuals (i.e., the difference between the observed and predicted values) of the model should be approximately normally distributed with a mean of zero. This can be assessed by creating a plot of the residuals against the fitted values and examining the pattern of the points. If the points form a roughly random pattern centered around zero, then the model is likely to be a good fit.
If all of these conditions are met, then a Poisson regression model may be a good choice for modeling the relationship between the response variable and the explanatory variables.
However, it is always important to carefully evaluate the assumptions of the model and confirm that it is an appropriate fit for the data.

From the Limit Comparison Test, the series converges absolutely. D. From the Integral Test, the series converges conditionally. E. The series diverges.
A. From the Limit Comparison Test, the series converges conditionally.
The Limit Comparison Test can be used to determine whether a given series converges or diverges. In this case, the given series is sigma^infinity_k = 0 9(-1)^k/k^4 + 2.
To use the Limit Comparison Test, we need to compare the given series to a known series. For example, we can compare it to the series sigma^infinity_k = 1/k^4.
We can then calculate the ratio of the two series:
sigma^infinity_k = 0 9(-1)^k/k^4 + 2
sigma^infinity_k = 1/k^4
Ratio: sigma^infinity_k = 0 9(-1)^k / (1/k^4)
Since the limit of the ratio of two series is a finite number, the given series converges. However, since the ratio is not 1, it converges conditionally, not absolutely.
Therefore, the answer is A - From the Limit Comparison Test, the series converges conditionally.

What is the formula for consecutive odd numbers?
The equation for adding "n" numbers in a row is [a + (a + 1) + (a + 2) +.... a + (n-1)]. As a result, (n/2) (first number + last number) is the sum of "n" consecutive numbers or "n" terms of AP (Arithmetic Progression). The formula for even consecutive numbers is 2n, 2n+2, 2n+4, 2n+6, and so on.
The next two odd consecutive integers are (2n + 3) and (2n + 5) if 2n + 1 is an odd number. For illustration, assume that 2n + 1 is the odd number 7. Its successive numbers are identified as (7 + 2) and (7 + 4), or 9 and 11. Consecutive odd numbers are odd integers that are separated by 2 and come after one another. If the number x is odd, then the numbers x + 2, x + 4, and x + 6 are also odd.
Any collection of consecutive odd numbers starting with 1 has a sum that is always equal to the square of the total number of digits. If the numbers 1, 3, 5, 7, 9, 11,..., and (2n-1) are odd, then the sum of the first odd number is 1. First two odd numbers added together equal 1 + 3 = 4 (4 = 2 x 2). Two successive odd numbers added together are always divisible by 4.

The circumference of a circle is 13π cm. What is the area, in square centimeters? Express your answer in terms of \piπ.
Answer:
The circumference of a circle is given by the formula $C = 2\pi r$, where $r$ is the radius of the circle. In this case, the circumference of the circle is $13\pi$ cm, so we can set up the equation $13\pi = 2\pi r$ to solve for the radius. Dividing both sides by $2\pi$, we get $r = \frac{13\pi}{2\pi} = \frac{13}{2}$ cm. The area of a circle is given by the formula $A = \pi r^2$, so the area of this circle is $A = \pi \left(\frac{13}{2}\right)^2 = \frac{169}{4}\pi$ square cm. Therefore, the area of the circle is $\frac{169}{4}\pi$ square cm.
