How large a sample is needed in order to be 98% confident that the sample proportion will not differ from the true proportion by more than 2%?

What is the solution of log2  (3x  -  7)  =  3? 4 5

Which expression do you get when you eliminate the negative exponents of 4a^2 b^216a^-3 b

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
