sergey [27]

Simple interest formula:

Total = principal x (1 + rate x years)

Total = $21,000

8 years:

Total = 15000(1+0.04x8)

Total = $19,800

Determine which of these sets are subsets of which other of these sets. Check ALL correct answers below.
noname [10]

The Set C is the subset of A and D.

According to the statement

we have given that the three sets which are A = {2, 4, 6}, B = {2, 6}, C = {4, 6}, and D = {4, 6, 8}.

And we have to find that the subsets of these sets.

So,

For a set S to be a subset of a set T, all of the elements of the set S need to be contained in the set T. Firstly, all of the sets are their own subsets, that is, A⊆A,B⊆B,C⊆C,D⊆D.

It follows that B⊂A because of 2∈A and 6∈A. Since 2 is not belongs to C and D. that's why B is not a subset of C and B is not a subset of D.

Taking into account that 4∈A and 6∈A, we conclude that C⊂A. By analogy, since 4∈D and 6∈D, we conclude that C⊂D.

Since |A|>|B|∣A∣>∣B∣ and |A|>|C|,∣A∣>∣C∣, we conclude that A is not a subset of B and A is not a subset of C.

Taking into account that |D|>|B|∣D∣>∣B∣ and |D|>|C|,∣D∣>∣C∣, we conclude that D is not a subset of B and D is not a subset of C. Since,2 not belongs to D that's why A is not a subset of D.

Since 8 not belongs to A, D is not a subset of A.

Overall, The Set C is the subset of A and D.
