Answer: LAST OPTION
Step-by-step explanation:
The formula for calculate the volume of a cone is:
Where r is the radius and h is the height.
The formula for calculate the volume of a cylinder is:
Where r is the radius and h is the height.
As you can see, the difference between the the formulas is that <em>r²hπ</em> of the cone is divided by 3. Therefore, if you know the volume of the cone and you know that cylinder has the same base and height as the cone, you have to multiply the volume of the cone by 3.
Therefore, the result is:
Answer:
Step-by-step explanation:
Notation
Total = n= 4+7+5=16 people
We are going to select 3 people and will be given gift certificates to a local restaurant so then r =3.
Determine the probability that two of those selected will be from the accounting department and one will be from the sales department.
For this case we can use combinatory nCx, since the selection is without replacment.
Where (nCx) means combinatory and it's given by this formula:
So then the definition of probability is given by :
Let's begin with the total outcomes, we have a total of n=16 people and we wan't to select 3 of them, so the possible outcomes are:
And now let's analyze the possible outcomes, we need that the group of 3 would be conformed by two people from the accounting department and one from the sales deparment. So then the possible outcomes are:
And the reason is because we have a total of 5 people at the accounting and we want to select 2. And we have a total of 4 people at the sales department and we want to select just 1. And the multiplication it's because the order on the selection no matter (we assume this).
So then replacing into our formula of probability we got:
