Sorry, what exactly is the question?
Answer:
0.66
Step-by-step explanation:
What are you giving there is a confidence interval. You can obtain a confidence interval based on a sample you got. The length of the confidence interval is determined on how much confidence do you want for your interval (the probability of the real value being inseide the interval) and how big is the sample: the bigger the sample, the smaller the length of the confidence interval. Independently of the sample length, all intervals are centered on the average value you got for the sample, and that is your estimate. In this case, the center of the interval is 0.52+0.8/2 = 0.66.
Answer:
uhh I thought there were only 8 BAHAHA
The surface area of the object above can be calculated by summing up all the areas of the surfaces. Therefore, we will have 5 surfaces with rectangles as the shape. The volume would be the product of the length, width and the depth. We calculate as follows:
SA = 2(depth)(length) + 2(depth)(width) + (width)(length)
SA = 324 yd^2
VOlume = 30x10x.3
Volume = 90 yd^3
9 places should be moved towards left
here eight zeros after decimal point
7.2 × 10-9 = 0. 0000000072
