Equation y = 94.38x + 38.17 fits the scatterplot of the values for stock ABC over the past month with an r-value of 0.9948. How much do you think ABC will be worth at x = 47 days?

A.$94.38 B

.$4474.03 C

.$4752.31

D.$38.17

Given the y = 94.38x + 38.17 with an r-value of 0.9948, it can predict the value of stock ABC in any x days. First, evaluate r^2. R^2 = (0.9948) (0.9948) = 0.98962704. R^2 is a statistical measure of the fitness of the data in a regression line. A value of almost 1 means, the scatter plot is almost liner. Fot this problem, by substitution the answer is B, $4474.03.
