Answer:
%55
Step-by-step explanation:
divide both values by 2, multiply by 10 to give you a percentage
Answer:
Step-by-step explanation:
Given that there are 3 sets such that there are 100 elements in A1, 1000 in A2, and 10,000 in A3
a) If A1 ⊆ A2 and A2 ⊆ A3
then union will contain the same number of elements as that of A3
i.e. 
b) If the sets are pairwise disjoint.
union will contain the sum of elements of each set

c) If there are two elements common to each pair of sets and one element in all three sets
We subtract common elements pairwise and add common element in 3
i.e. 
So, what I did was multiply 33*6 and got 198 and then 228-198 to find out that the initial fee was 30 dollars. then multiply 33*9+30 to get a 9 month total cost of $327. Hope from here you are able to set up your equation now you have all the information needed :)
Step-by-step explanation:
mean is always equal to additon of total no.s by total no.s
2 + 4 + 6 + 8 + 10 + 12
=42
total no.s = 6 no.s
42/6
=7
therefore 7 is the answer which is the mean deviation of the following no.s .
