450 people are randomly selected at grocery stores across the state and surveyed on the amount of money they are spending at the store that day. How does finding the sample variance compare to investigating the sampling distribution of the variance?A.Since the state has at least 450 grocery stores, finding the variance of the sample is the same as investigating the sampling distribution of the variance.B.The sampling distribution of the variance requires repeating this process with the same sample several times. So this does not compare to the sampling distribution of the variance.C. Only 450 people are selected from all the shoppers, so the distribution is not even.D.The sampling distribution of the mean requires multiple samples to be compared. However, in this situation you are looking for the variance, so finding the sample variance is the same as investigating the sampling distribution of the variance.

A surveying instrument aimed at a location can “shoot” the distance to the location, giving the surveyor a measurement. A surveyor used such an instrument to record the distance to a point on a tree 60 m from his position. After rotating his surveying instrument 57° to the left, he measured the distance from his same position to a fence post 35 m away. a.) Draw the diagram and label the tree as point T, the surveyor as point S, and the fence post as point F.b.) Determine the distance between the point on the tree and the fence post. (Show the appropriate formula, substitutions, and work. Give the distance to the nearest tenth of a meter.)c.) Use the Law of Sines to find the measure of T.
