Consider the tire-testing data described in exercise 8-29. compute a 95% prediction interval on the life of the next tire of this type tested under conditions that are similar to those employed in the original test. compare the length of the prediction interval with the length of the 95% ci on the population mean.

The length of triangle base is 26. a line, which is parallel to the base divides the triangle into two equal area parts. find the length of the segment between triangle legs.

If f(x) = 2x + 8 and g(x) = x4, what is (gº)?

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
