Well, there is 10 marbles in total and there is 2 black marbles. So, you get 2/10 but you need to simplify it and then you get 1/5.
31 and 15
31+15=46
31-15=16
A compass and straightedge are supposed to be part of the required equipment for your class. You are expected to use them here. Your assignment paper should be complete with pencil marks and holes from the compass point. Nobody can do it for you on-line.
Here is a picture of the first one worked. The remaining ones are just like it. The whole assignment should take about 3 minutes, tops.
Answer:
She need need 0.5 more cups of water.
Step-by-step explanation:
If you do 5 - 4.5 it will equal 0.5.
Considering the situation described, the confidence interval is given by:
(0.35, 0.51).
<h3>What is a confidence interval?</h3>
It is given by the <u>estimate plus/minus the margin of error</u>.
For this problem, we have that:
- The margin of error is half the range of the observations, hence M = (0.48 - 0.32)/2 = 0.08.
Then, the bounds of the interval are given by:
