Numerals and Sets

Use the following sets. Set = U = {0,1,2,3,4,5,6,7,8,9}; A = {1,2,3,4,5,7}; B = {0,2,4,6,7,8}; C = {1,3,4,8}, find B'

• {1,3,5,9}

• {0,2,4,6,7,8}

• {0,1,2,3,4,5,6,7,8,9}

• {0,1,3,5,8,9}

Use the Venn diagram to answer the question if the number in each set represents numbers of elements: How many are in C but not in B?

• 17

• 22

• 15

• 4

• True

• False

Match the graph with its inequality. hint: don't be tricked by the variable on the right.

• 11 < a

• 11 > a

• 11 ≤ a

• 11 ≥ a

Pick the correct letter for:
6 > x

• A

• B

• C

• D

What inequality does the number line graph represent?

• x ≤ 4

• x ≥ -4

• x < -4

• x < 4

Which graph matches the inequality 
¹/₂ > b?

• A

• B

• C

• D

Solve for x:

• x = 20

• x = 7

• x = 10

• x = 3

True or False: The ratio of red circles to green circles is 4:7.

• True

• False

• 1 - 2
