Answer:
Step-by-step explanation:
One of the more obvious "connections" between linear equations is the presence of the same two variables (e. g., x and y) in these equations.
Assuming that your two equations are distinct (neither is merely a multiple of the other), we can use the "elimination by addition and subtraction" method to eliminate one variable, leaving us with an equation in one variable, solve this 1-variable (e. g., in x) equation, and then use the resulting value in the other equation to find the value of the other variable (e. g., y). By doing this we find a unique solution (a, b) that satisfies both original equations. Not only that, but also this solution (a, b) will also satisfy both of the original linear equations.
I urge you to think about what you mean by "analyze connections."

Answer:
<u>The z-score = -3.7 and p (-3.7) = 0.00011 or 0.011%</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Mean of time to finish a test = 60 minutes
Standard deviation of time to finish a test = 10 minutes
Time that a student finishes the test = 23 minutes
2. What is the z-score for the student?
z-score = (Time that a student finishes the test - Mean of time to finish a test)/Standard deviation of time to finish a test
Replacing with the real values:
z-score = (23 -60)/10 = -37/10 = -3.7
<u>z-score = -3.7 and p (-3.7) = 0.00011 or 0.011%</u>
