The following subsets you can be able to create are:
{1}
{2}
{3}
{1,2}
{1,3}
{2,3}
{1,2,3}
Therefore, there are 7 subsets in all. However, we don't have to list all these possible outcomes because we could waste our time doing this but there is a formula, that is 2^n - 1 where n is a number of elements.
In the given, since there are 3 elements inside the set then we use 2^3 - 1 = 8 - 1 = 7.
See...it's easy.
Answer:
We will divide the 15 days in five periods of 3 consecutive days each.
Now to solve this we will use the pigeonhole principle.
This states that if (N+1) pigeons occupy N holes, then some hole must have at least 2 pigeons.
So, we have n=300 pigeons and k=5 holes.
![[\frac{n}{k} ]=[\frac{300}{5} ]](https://tex.z-dn.net/?f=%5B%5Cfrac%7Bn%7D%7Bk%7D%20%5D%3D%5B%5Cfrac%7B300%7D%7B5%7D%20%5D)
Hence, there is a period of 3 consecutive days in which the website was hit at least 60 times.
That means 2*3* the sum of 5+8 which gives you 78 as your answer. Hope this helps and please select as the brainliest answer.
The train Chug-a-Lug must be going 153.5 miles to match the same speed as Old Steamy so they can arrive at the station at the same time.
Answer:
.125
Step-by-step explanation:
The volume of a cube is found by
V = s^3 where s is the side length
V = .5 ^3
V =.125 m^3
