If a scope sits above a rifle barrel, how can it ever be accurate, except for a very specific distance? Wouldn't there be only one point that two straight lines with different origins could ever intersect each other? Free points - no answer needed!

Abby is collecting rainfall data. she finds that one value of the data set is a high-value outlier. which statement must be true? abby will use a different formula for calculating the standard deviation. the outlier will increase the standard deviation of the data set. the spread of the graph of the data will not change. abby will not use the mean when calculating the standard deviation.
