The answer cannot be determined from the information provided.

Answer: Option B.

<u>Explanation:</u>

A linear regression line has an equation in the form Y = a + bX, where X stands for the explanatory variable and Y is used to denote the dependent variable in the equation. The slope of the line is b, and a is the intercept (the value of y when x = 0).

A regression line (LSRL - Least Squares Regression Line) is a straight line that explains how a dependent variable y changes as an explanatory variable x changes. The line is a mathematical model used to predict the value of y for a given x. Regression requires that we have an explanatory and response variable.

Suppose that the pound is pegged to gold at 6 pounds per ounce, whereas the franc is pegged to gold at 12 francs per ounce. This
zmey [24]

Answer:

we can look at this problem from 2 different point of views:

if you have francs and wish to buy pounds: then you take 12 francs and purchase 1 ounce of gold, and then you sell it for 6 pounds. This way you will only spend 2 francs per each pound instead of 2.2.

if you have pounds and want to make a gain: you take 6 pounds and purchase 13.2 francs and you then buy 1.1 ounces of gold. Then you sell the 1.1 ounces of gold in exchange for 6.6 pounds.

Any of the scenarios does not include any transaction prices nor shipping costs, it is only theoretical.
