A is one of them i dont know the others
Answer:
Here we will use the relation:
Density = mass/volume.
We know that:
Mass = 1485g
Volume = 750L
Density = 1485g/750L = 1.98 g/L
We do not have the options in order to select the correct one, but knowing this density, we can suppose the possible gases.
Two "common" gases with densities similar to this one are:
Carbon Dioxide, with d = 1.977 g/L
Dinitrogen Monoxide, with d = 1.977 g/L
In both cases, if we round up we will get the same density that we calculated at the beginning, so either of these can be the correct option.
Answer:

Step-by-step explanation:
Given
---- 10 sided
--- 6 sided
Required

First, list out the sample space



--- total outcomes
The event that the outcome of both is greater than 4 is:


So, the probability is:



<em>they </em><em>both </em><em>would </em><em>have </em><em>2</em><em>4</em>
<em> </em><em>they </em><em>both </em><em>would </em><em>have </em><em>2</em><em> </em><em>successful</em><em> </em><em>shots.</em><em> </em><em>they </em><em>would </em><em>mean </em><em>that </em><em>the </em><em>older </em><em>brother</em><em> </em><em>added </em><em>4</em><em> </em><em>point </em><em>to </em><em>his </em><em>score </em><em>and </em><em>the </em><em>younger </em><em>brother</em><em> </em><em>would </em><em>have </em><em>added </em><em>6</em><em> </em><em>to </em><em>his </em><em>score</em>
