21. The answer is 453. I put it in the calculator and got 452.5, so I rounded to 453. If it's 5 or more round up, 4 or less round down.
22. 14.1 I did the same thing it came out as 14.06, but the 6 made me round to 1.
23. $4.1 I think you get the concept now.

Calculate this product to help you solve the problem
saveliy_v [14]

Answer:

7a

Step-by-step explanation:

We don't actually know the variable A and we don't have a final product to help us solve it, so the best we can do is make 7 a coefficient to the variable A, making the answer 7a.

Let A = {a, b, c, d, e} and B = {a, c, f, g, i}. Universal Set: ∪= {a,b,c,d,e,f,g,h,i}
mixer [17]

Answer:

1. { a, b, c, d, e, h }

2. { f, g, i }

Step-by-step explanation:

Given sets,

A = {a, b, c, d, e},

B = {a, c, f, g, i}

Universal set , ∪ = {a, b, c, d, e, f, g, h, i},

1. Since, B^c = elements of universal set which are not in set B

=  U - B

= { b, d, e, h },

Thus,

A\cup B^c = All elements of A and B^c

= { a, b, c, d, e, h }

2. B - A = elements of set B which are not in set A

= { f, g, i }
