A forecaster would like to use the 2-period moving average method on data below to make forecasts. Before doing this, she would like to test the performance of this method on past data. Which of the following could represent past forecasts for this method? (In the options below note that F1 represents the forecast for time period 1, and so on.)

Select one:

a. F1 = 5543.2 F2 = 5543.2 F3 = 5543.2 F4 = 5543.2 F5 = 5543.2

b. F1 = 5582 F2 = 5244 F3 = 5330.5 F4 = 6037.5 F5 = 5736.5

c. F2 = 5244 F3=5244 F4 = 5330.5 F5 = 6037.5

d. F3 = 5330.5 F4 = 6037.5 F5 = 5736.5

e. F3=5244 F4 = 5330.5 F5 = 6037.5

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser

step-by-step explanation:

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
