A social scientist researched how the average working hours per worker, over a full year, for two different European countries changed since 1870. she created a scatter plot and found the regression line for each set of data. She then used the regression line to
create a table of values for the residuals. The scatter plots, regression equation, and residuals for the two countries are shown, where z represents the number of years since 1870 and y represents the average working hours per worker over a full year.
We can conclude that (B) the data from Germany has a negative correlation because the slope of the regression equation is negative.
What is a regression equation?The dependent variable's predicted value in simple linear regression is given by the equation = b₀ + b₁x. In order to minimize the total sum of squared errors, the values of b0 and b1 are calculated from the data using the equation line = b0 + b1X. (the error is the difference between the predicted value and the actual value of y).When two variables, X and Y, are involved, there will be two regression lines: one for X on Y and one for Y on X. Lines of regression X and Y: In this configuration, the variables Y and X are independent, and the best-expected value of X is determined in accordance with the value of Y that is provided.So, according to the given image, we can easily say that Germany has a negative correlation.
Hence, option(C) and (D) are wrong.We can observe that the slope of the regression equation is negative.
Then, the wrong option will be (A) and the correct option will be (B).Therefore, we can conclude that (B) the data from Germany has a negative correlation because the slope of the regression equation is negative.

I need help with this question... the correct answer choice
The transformation on a line such that a line is obtained which is pependicular to previous line is possible only when it is reflected through y = x axis. This can be understood as,
When line is reflected about x-axis, the x coordinate remain same where as y-coordinate changes in opposite sign with same magnitude. So reflection of line x = 3 about x axis remain same.
Simillarly reflection of line x = 3 about x = 1 remain same as x = 3.
The reflection of line x = 3 about y-axis results n a parallel line passing through x = -3.
So answer is reflection across y = x.

In comparative statistics, what type of error occurs when a test indicates a significant difference between two or more populations even though the null hypothesis is true?.
Type 1 error is the error occurs when a test indicates a significate difference between two or more populations.
What does a Type I mistake mean?Rejecting the null hypothesis when it is in fact true is a Type I mistake. It entails drawing conclusions about outcomes that are statistically significant when, in fact, they were just the consequence of chance or unrelated causes. The significance level you select (alpha or ) determines the likelihood that you will make this mistake.
Data cleansing—also known as data cleaning, data scrubbing, or data rectification—is the process of correcting inaccurate, insufficient, duplicate, or other wrong data in a data set. It entails locating data mistakes and then correcting them by modifying, updating, or eliminating data.
Using independent samples from two independent groups, the two-sample (independent groups) t-test is used to assess whether the unknown means of two populations are different from one another.

Find the equation to the line below.y =[?-x ++ [ ]
Note that a line whose equation is in the form :
[tex]y=mx+b[/tex]has a slope of m
and a y-intercept of b
Slope is also equal to rise/run :
[tex]m=\frac{\text{rise}}{\text{run}}[/tex]where rise is the number of vertical units between two points and run is the number of horizontal units between two points.
Note also that upward and right movement is positive, downward and left movement is negative.
From the figure, the vertical units between two given points is 3 units upward, so this is positive.
The horizontal units between them is 2 units to the right which is also positive.
The slope will be :
[tex]m=\frac{\text{rise}}{\text{run}}=\frac{3}{2}[/tex]Next is to solve for b (y intercept).
y-intercept is the point where the line intersects the y-axis.
From the graph, the lines intersects at point (0, 2) on the y-axis
Therefore, the value of b is 2

Use point-slope form to write the equation of a line that passes through the point (-12,15) with slope -1.
The equation that passes through (-12, 15 with a slope of -1 in point slope form is y - 15 = - 1(x + 12)
How to represent equation in point slope form?Linear equation can be represented in different form such as point slope form, slope intercept form and standard form.
Therefore, let's represent the line that passes through (-12, 15) with a slope of -1 in point slope form.
Hence,
y - y₁ = m(x - x₁)
where
m = slopey₁ and x₁ are the coordinates of the point.Therefore,
m = slope = -1
using (-12, 15)
Hence,
y - 15 = - 1(x - (-12))
Therefore,

There are 54% of the participants are female.
What is percent?A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a standard measurement.
%, which is a relative figure used to denote hundredths of any quantity. Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified. percentage
Given:
There are 104 males and 121 females

Ariel dropped a golf ball from her second story window. The ball starts from rest and hits the sidewalk 1.5 s later with a velocity of 14.7 m/s. Find the average acceleration of the golf ball.
The average acceleration of the golf ball as it was dropped from the second story window is 9.8m/s².
Given in the question is:
Since the ball started from rest
Initial velocity; u= 0m/s
Final velocity; v = 14.7 m/s
Time taken for the golf ball to hit the sidewalk; t = 1.5 s
Average Acceleration; g =?
To determine the average acceleration of the golf ball, we use the First Equation of Motion:
v = u + at
The Equation will be :
v = u + gt
Plug the all values in above equation:
14.7m/s = 0 + g x 1.5 s
g = 14.7 / 1.5
g = 9.8m/[tex]s^2[/tex]

Determine a series of transformations that would map Figure I onto Figure J
and its not just rotate the figure 90 degrees clockwise, you have the do TWO translations
3 × 90 thus equals 280 degrees.
The figure moves onto the following quadrant of the graph with each 90 degree rotation. In order to shift Figure I to the location of Figure J, you must move the three figure quadrants in a clockwise direction. 3 × 90 thus equals 280 degrees. Only one transformation is needed.
Which transformation corresponds to turning a figure 90 degrees counterclockwise?
The coordinate transformation (x, y) (y, x) is equivalent to a rotation of the origin 90 degrees counterclockwise. The coordinate transformation (x, y) (x, y) is comparable to a 180 degree counterclockwise rotation of the origin.
Our point A(x,y) becomes A' when a point is rotated 90 degrees counterclockwise about the origin (-y,x). To put it another way, flip x and y, making y negative.

You are a grant writer for an organization that helps adults complete their high school educations. For the last 5 years, you have applied for and received $45,000.00 in grants. Your boss would like you to try to increase that amount to $60,000.00. How much of an increase does the new amount represent over the previous amount?
Based on the amount you have received in grants, and the amount the boss wants to increase it to, the increase the new amount represents over the previous amount is $15,000 or 33.3%.
How to find the increase?Your boss wants to increase the grants to $60,000 from the current amount of $45,000.
This means that the new amount will represent an increase over the previous amount by:
= 60,000 - 45,000
= $15,000
In percentage terms this is:
= Increase over previous amount / Previous amount x 100%
= 15,000 / 45,000 x 100%
= 33.3%

(2)The equation of the line is y = x + 3.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
The points are ( 3, 0 ) and ( 0, 3). The slope of the line will be calculated as:-
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = ( 3 - 0 ) ( 0 - 3 )
Slope = 1
Calculate the y-intercept,
y = mx + c
3 = 0 + c
c = 3
