Answer:
C = $2.40
n = 6
Step-by-step explanation:
For Noelle,
Equation that represents the monthly cost 'C',
C = 0.2n + 1.20
Here, n = number of checks written in a month
For Micah,
Monthly cost for writing checks 'C' = $1.20
Number of checks 'n' = 3
Since, Cost of writing checks ∝ Number of checks written
C' ∝ n
C' = kn
k = 
Here, k = proportionality constant
For C' = 1.2 and n = 3
k = 
k = 0.4
Equation will be,
C' = 0.4n
For any month C = C'
Therefore, 0.2n + 1.20 = 0.4n
0.4n - 0.2n = 1.20
0.2n = 1.20
n = 6
Number of checks written by Noelle and Micah = 6
For n = 6,
C = 0.2(6) + 1.20
C = $2.40
Cost of writing checks = $2.40

Predictor variable: proximity from primary residence to farmland (in miles) outcome variable: animal rights opinion (scale from 0-50) correlation coefficient is the appropriate inferential statistic.
What is a predictor and response variable?
- Response or dependent variables are the variables that are of interest in an experiment and are measured or observed.
- Predictor, explanatory, or independent variables are any additional factors in the experiment that may be controlled or assessed by the researcher and have an impact on the answer.
What is a predictor variable example?
In personnel selection, for example, predictors such as qualifications, relevant work experience, and job-specific abilities (e.g., computer competence, ability to speak a certain language) may be used to estimate an applicant's future job performance.
Is a predictor variable dependent or independent?
- The risk factors and confounders are referred to as the predictors, or explanatory or independent variables, whereas the outcome variable is also known as the response or dependent variable.
- The independent variables are designated by "X" while the dependent variable is denoted by "Y" in regression analysis.
