Answer:
The second one:
L∪J={i,j,k,l,m,n,o}
Step-by-step explanation:
The union is the elements listed in either set.
So since l,m,n, and o are elements of set L, they will also be elements of whatever it is "unioned" with.
Since i,j,k,l and m are elements of set J, they will also be elements of whatever it is "unioned" with.
When you write the union, just be sure to include each element that occurs in either set once.
So the union of L and J is {i,j,k,l,m,n,o}.
The answer is the second one.
The intersection would actually be that upside down U thing, the ∩ symbol. The intersection of two sets is a list of elements that both sets include. So here the intersection would just consist of the elements l amd m.
56 is what I got.
Hope this helps
Answer: 4 days (I think)
Step-by-step explanation:
One cat = 150*2 = 300g
Two cats = 600g
600*2 = 1200 (this is the total amount of food they both eat in a day)
5kg = 5000g
1200g/5000g = 4.17
The bag will last 4 days.
Answer:
52
Step-by-step explanation:
When asked such a question, try to use trial and error.
For example, the total is 202 and is made of of 4 integers which are <u>consecutive</u>(follow each other)
If you were to divide 202 by 4, you would get approximately 50
So, it would be best to try and add certain consecutive numbers(making sure 50 is one of them) till you get a total of 202
In this case, the integers would be, <em>49, 50, 51</em> and <em>52</em>
The question then further asks you ti find out which is the greatest of these integers. That would be <em>52</em>
