Closeness of primary dwelling to farmland as a predictor (in miles) outcome variable: support for animal rights (scale from 0-50) The proper inferential statistic to use is the correlation coefficient.
What is a predictor and response variable?
The variables that are measured or observed in an experiment are called response or dependent variables. Any other elements in the experiment that the researcher may be able to control or evaluate and that may have an effect on the result are known as predictor, explanatory, or independent variables.A predictor variable example is what?
When choosing employees, for instance, potential employees' future job performance may be predicted using factors like their qualifications, relevant work experience, and job-specific skills (such computer proficiency or the ability to speak a particular language).Is a predictor variable dependent or independent?
The result variable is sometimes referred to as the response or dependent variable, whereas the risk factors and confounders are known as the predictors, explanatory, or independent variables. Regression analysis uses the notation "X" for the independent variables and "Y" for the dependent variables.Learn more about predictor variable

Which of the following statements is true?
This is a skewed-left distribution, because the mean is less than the median.
O This is a skewed-right distribution, because the mean is less than the median.
This is a skewed-left distribution, because the mean is greater than the median.
This is a skewed-right distribution, because the mean is greater than the median.
Because the mean is the same as the median, this distribution is roughly symmetric.
The correct option regarding the skewness of the distribution is given by:
This is a skewed-left distribution, because the mean is less than the median.
Given the mean and the median of a distribution, how we classify it's skewness?If the mean is greater than the median, the distribution is right-skewed, also called positively skewed. Otherwise, if the median is greater than the mean, the distribution is left-skewed, also called negatively skewed.
In this problem, we have that:
The mean is of 10.4.The median is of 13.4.The median is greater than the mean, hence the correct option is given by:
This is a skewed-left distribution, because the mean is less than the median.

Juan and jaquan work for separate companies. juan earns $15 for each sale plus 5% commission. jaquan earns $21 for each sale plus 3.5% commission. in july, juan made 35 sales and jaquan made 29 sales. they made the same total salary. which equation can be used to find x, the amount juan & jaquan each had in sales in july?
The amount Juan & Jaquan each had in sales in July is approximately $725 and the equation for Juan's Earning is 525 + 1.75x and the equation for Jaquan's Earning 609 + 1.015x.
Unitary method:
Unitary method is defined as the process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Given,
Juan and Jaquan work for separate companies.
Juan earns $15 for each sale plus 5% commission.
Jaquan earns $21 for each sale plus 3.5% commission.
In July, Juan made 35 sales and Jaquan made 29 sales.
They made the same total salary.
Here we need to find the amount Juan & Jaquan each had in sales in July.
Let x be the total number of sales in July.
So, based on the given details we can written it as,
Juan earns,
=> 15 + 5%x
=> 15 + 0.05x
And Jaquan earns,
=> 21 + 3.5%x
=> 21 + 0.035x
So, in July, Juan made 35 sales and Jaquan made 29 sales,
Then
=> 35(15 + 0.05x)
=> 525 + 1.75x -----------(Juan's Earning)
=> 29(21 + 0.035x)
=> 609 + 1.015x -----------(Jaquan's Earning)
And also in July, they made the same total salary.
So,
Juan's Earning = Jaquan's Earning
Then,
=> 525 + 1.75x = 609 + 1.015x
=> 1.75x - 1.0.15x = 609 - 525
=> 0.735x = 84
=> x = 84 / 0.735
=> x = 114.28
So, the total amount they earned in July is,
=> 525 + 1.75(114.28) = 609 + 1.015(114.28)
=> 525 + 199.99 = 609 + 115.99
=> 724.99 = 724.99
So, they earned approximately $725 in July.

30g to the 5th power/6g to the 9th power
Answer:
5.0 × 1012 kg-4. I'm pretty sure this is the answer
Answer:
2.41
Step-by-step explanation:
We needed split up 30 into 2 factors where one of them had to be the same number on the bottom. Since 6 is on the bottom we need to find a number that multiples with 6 to get to 30 and 30/6 gives us 5. So then we can split up 30g into 5g *6g and with the exponents of course. Now since 5g and 6g are multiplying, we can just take 5g out of the equation. If they were adding or subtracting we couldn't.So that gives us 5g^5 * (6g^5/6g^9). According to exponent laws or whatever they're called, if 2 numbers have the same base and have exponents, we can add or subtract the exponents if they are being multiplied or divided by each other. Therefore our final answer is 2.41.
What is the y-intercept of the line that is perpendicular to the line 7x+2y=14 and passes
through the point (7,-6)?
Considering the definition of perpendicular line, the y-intercept of the line that is perpendicular to the line 7x+2y=14 and passes through the point (7,-6) is -8.
Linear equationA linear equation o line can be expressed in the form y = mx + b
where
x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.Perpendicular linePerpendicular lines are lines that intersect at right angles or 90° angles. If you multiply the slopes of two perpendicular lines, you get –1.
Equation of perpendicular line in this caseIn this case, the line is 7x+2y=14. Expressed in the form y = mx + b, you get:
2y= 14 - 7x
y= (-7x + 14)÷ 2
y= -7/2x - 7
If you multiply the slopes of two perpendicular lines, you get –1. In this case, the line has a slope of -7/2. So:
-7/2× slope perpendicular line= -1
slope perpendicular line= (-1)÷ (-7/2)
slope perpendicular line= 2/7
So, the perpendicular line has a form of: y= 2/7x + b
The line passes through the point (7,-6). Replacing in the expression for perpendicular line:
-6= 2/7× (7) + b
-6= 2 + b
-6 -2 = b
-8= b, being b the y-intercept of the line.
Finally, the y-intercept of the line that is perpendicular to the line 7x+2y=14 and passes through the point (7,-6) is -8.

c. $1250
Answer:
it should be b.
Step-by-step explanation:

The function with the largest slope would be f(x) = 1.5
What is the slope in math?
The inclination of a line with respect to the horizontal is measured numerically. The ratio of the vertical to the horizontal distance between any two points on a line, ray, or line segment is known as its slope in analytic geometry ("slope equals rise over run").For f(x), choose any two points say (-3,-10) and (-1,-7) where
x1 = -3 ; y1 = -10 ; x2 = -1 ; y2 = -7
Find the slope (m)
m=(y2 - y1) / (x2 - x1) = (-7 - -10)/ (-1 - -3) = 3/2 or 1.5
slope of f(x) = 1.5
g(x) = 1/2 x + 3
standard formula: y = mx + b where m is the slope.
slope of g(x) = 1/2 or 0.5
Since lance gains 1 level every time he plays,
slope = 1/1 = 1 so, slope of h(x) = 1

In a chi-square test, as the value of the χ2 increases, the likelihood of rejecting the null hypothesis ________.
If the chi-square value is going on English the likelihood of rejecting the null hypothesis also increases because there is a chance that the chi-square value increases more than the significant value that is given in the question. So the required answer is that increases as the required answer.
For example, if, according to Mendel's laws, you expected 10 of 20 offspring from a cross to be male and the actual observed number was 8 males, then you might want to know about the "goodness to fit" between the observed and expected.
Were the deviations (differences between observed and expected) the result of chance, or were they due to other factors? How much deviation can occur before you, the investigator must conclude that something other than chance is at work, causing the observed to differ from the expected.
The chi-square test is always testing what scientists call the null hypothesis, which states that there is no significant difference between the expected and observed result.
