Which of the following shows the union of the sets? {3, 6, 9, 12, 15} {1, 6, 12, 18, 24}

A ∪ B = {1,3,6,9,12,15,18,24}

Step-by-step explanation:

Let A = {3,6,9,12,15}

B = {1,6,12,18,24}

So,

A ∪ B = {3,6,9,12,15} ∪ {1,6,12,18,24}

A ∪ B = {1,3,6,9,12,15,18,24}

{1,3,6,9,12,15,18,24}

Step-by-step explanation:

The union is joining of the elements of the sets

{3, 6, 9, 12, 15}U {1, 6, 12, 18, 24}

= {1,3,6,9,12,15,18,24}

A. the water level increased by 0.25 ft per day

D. even though it states how long it was measured for, it does not have anything important there

C. It tells us the initial water level but not if it increased or decreased over the 2 weeks

B. It tells us the maximum water level was 19.5 ft Yet it doesn't tell us what the water level was starting off with or what it ended off with.
