The correct couples are:
1) Lurking variable
Lurking variables are random variables related to the variables you want to study and which affect them. Their effect is often unnoticed (that is why they are lurking), but they make stronger or weaker the relationship between the explanatory and responsive variables.

2) Line of best fit
The "line of best fit" is the straight line that best represents the data in a scatter plot. The least squares method provides the steps needed to find which line minimize the difference between the expected and the observed values. Therefore, "line of best fit" and "least squares regression line" are synonymous.

3) Correlation coefficient
A correlation coefficient is a number that represents the statistical relationship between two variables. Pearson's coefficient r is a measure of the strength and direction of the linear relationship between two variables.  

4) Correlation
An association is, in statistics, any relationship between two variables. A correlation is a measure of how strongly two variables have a linear relationship with each other. Therefore, "correlation" and "association" are synonimous.

5) Causation
The term "causation" means that there is a "cause and effect" relationship between two events, meaning that one event occurs because an other event has occured. Hence, <span>there is a causal relationship between the two events.</span>

Remote interior angles are the two angles of a triangle that are not adjacent to the exterior angle which is drawn by extending one of the sides. So when you draw out your triangle, the remote interior angles are the two angles that are the furthest away from your exerior angle.

In this case your exterior angle would be <6

I hope this helps

Ariane borrows $200 on a 5 year loan she is charged 5% simple interest how much interest is she charged for 5 years what is the
ycow [4]

Answer:

Interest: $50 | Total: $250

Step-by-step explanation:

You are going to want to use the simple interest formula for this. The one below is modified for solving the interest earned.

I = Prt

<em>I = interest amount </em>

<em>P = principal amount </em>

<em>r = interest rate (decimal form) </em>

<em>t = time</em>

<em />

Now we can plug in the values into the equation:

I = 200(.05)(5)

I = 50

This means that Ariane is charged $50 worth of interest. She has to pay back $250 total dollars.
