Suppose that A = (2, 4) are the coordinates of a point in the xy-plane. a) Find the coordinates of the point if A is shifted 2 units to the right and 3 units down.
b) Find the coordinates of the point if A is shifted 1 unit to the left and 7 units up.
a) The coordinates of the point are if A is shifted 2 units to the right and 3 units down.
(Simplify your answer. Type an ordered pair.)

Which answer goes into the box? (90° clockwise rotation, 90° counter clockwise rotation, translation, or glide reflection)

Acell phone company offers two plans to its subscribers. at the time new subscribers sign up, they are asked to provide some demographic information. the mean yearly income for a sample of 40 subscribers to plan a is $45,000 with a standard deviation of $9,200. for a sample of 25 subscribers to plan b, the mean income is $64,300 with a standard deviation of $7,100. at the 0.025 significance level, is it reasonable to conclude the mean income of those selecting plan b is larger? assume unequal population standard deviations. hint: for the calculations, assume the plan a as the first sample. what is the decision rule?
