If there is a relationship between dependent and independent variables represented in a scatterplot, The independent variable influences change in the dependent variable whether the points on the scatterplot go up or down from left to right.
The independent variable is the one that influences the dependent variable. If there is a relationship between them, it doesn't matter the direction of the points in the scatterplot, but the correlation coefficient.
If the points go up from left to right, the correlation is called direct correlation (increasing the value of the independent variable will increase the value of the dependent variable).
If the points go down from left to right, the correlation is called inverse correlation (increasing the value of the independent variable will decrease the value of the dependent variable)
Have a nice day.
Answer: Our required probability is 0.64.
Step-by-step explanation:
Since we have given that
Let A be the event that he upgrades his seat to first class.
Let B be the event that he checks in at least 2 hours early.
Let B' be the event that he does not checks in at least 2 hours early.
So,
By using Bayes' theorem, we get that
Hence, our required probability is 0.64.
Answer:
7/8 (seven eighths)
Step-by-step explanation:
add the numerators (top numbers) together, to get 7. Leave the denominator (bottom number) alone, since they are the same. Think about it like you're adding two different parts of a whole.
you should get 7/8
hope this helps
The answer is y=1.2x because you can plug in 1.2x4 and get 4.8
