Match the following. given a = {1, 2, 3, 4, 5} b = {2, 4, 6} c = {1, 3, 5} 1. a ∪ b {1, 2, 3, 4, 5, 6} 2. a ∪ c {2, 4} 3. a ∩ b {1, 3, 5} 4. a ∩ c null, or empty set 5. b ∩ c {1, 2, 3, 4, 5}

Given sets,

A = {1, 2, 3, 4, 5},

B = {2, 4, 6},

C = {1, 3, 5}

1. A ∪ B = all elements of sets A and B

= {1, 2, 3, 4, 5, 6}

2. A ∪ C = all elements of sets A and C,

= {1, 2, 3, 4, 5}

3. A ∩ B = common elements of sets A and B

= { 2, 4 }

4. A ∩ C = common elements of sets A and C

= { 1, 3, 5}

5. B ∩ C = common elements of sets B and C

= ∅ ( null or empty sets )

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
