Answer:
A. There is a moderately good fit between the regression line and the individual data points on the scatterplot.
Explanation:
A -.5 correlation coefficient indicates a moderate negative correlation, which means that as the x variable increases in value, the y value decreases in value, but only in around half of the situations.
In a scatter plot, this will look like a small cloud of data points that fit more or less well around the regression line. The regression line slopes downward because the variables are inversely proportional (hence the negative coefficient).

Answer:
He has lost the previous files as he has been replacing them.
Explanation:
When you save a file in your computer, you need to save it with a name that is different from the names of the other files you have in the computer. If you save file with the same name of another file, you will replace that file and will lose the information you had. So according to this, as Jack is saving all his work for the class with the name of the course, it means that he has saved everything with the same name and he has lost the previous files because everytime he saves a new file he replaces the previous one.
