The total number of thousands of tons of coal produced per year over a​ 10-year period for a certain region is provided in the accompanying dataset. Use double exponential smoothing to determine which pairs of values for alpha and beta minimize MAD for this dataset. alphaequals0.1​, betaequals0.9​; alphaequals0.4​, betaequals0.2​; alphaequals1​, betaequals0.7

Drag the tiles to the correct boxes to complete the pairs. match the cart-coordinates with their corresponding pairs of y-coordinates of the unit circle

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough

If you prove that ∆wxz is congruent to ∆yzx, which general statement best describes what you have proved?
