Describe the sample space for this problem: 1200 students at a certain school, all with equal probability of being selected on a random draw.
Which outcome (or outcomes) of the sample space compose the event?
Sophie wins the bike. The chances that that will happen are 1/1200, or 0.00083...
By looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.
C= pi multiplied by diameter
Here is how I completed the problem:
I started by creating a ratio:

<em>Where 'x' is the desired amount of the 18% solution of sulfuric acid.
</em>From here, I solved for 'x':
<em>
</em>







∴You will need to add 1080ml of 18% Sulfuric Acid in order to obtain a 15% solution.
