Use inductive reasoning to predict the next line in the pattern.

1) (7 × 1) × (2 × 1) = 14

(7 × 10) × (2 × 2) = 280

(7 × 100) × (2 × 3) = 4200

Use inductive reasoning to predict the next number in the sequence.

2) 2, 8, 14, 20, 26

Estimate the answer by rounding.

3) 98 + 37 + 66 + 62 + 18

4)

32,478

476

Express the set in roster form.

5) {x|x is a whole number between 1 and 5}

Find n(A) for the set.

6) A = {6, 8, 10, 12, 14}

1

Construct a Venn diagram illustrating the following sets.

7) U = {2, 4, 6, 8, 10, 12}

A = {2, 6, 10}

B = {2, 4, 8}

C = {2, 8, 10, 12}

Solve the problem.

8) Monticello residents were surveyed concerning their preferences for candidates Moore and Allen in an upcoming

election. Of the 800 respondents, 300 support neither Moore nor Allen, 100 support both Moore and Allen, and

250 support only Moore. How many residents support Moore or Allen?

Solve the problem. Round to the nearest hundredth.

11) What is 82% of 203?

2

12) 110% of 385 is what number?

Solve the problem. Where appropriate, round to the nearest tenth of a percent.

13) The price of a printer was reduced from $400 to $ 300. What was the percent decrease?

Find the simple interest. (The rate is an annual rate unless otherwise noted. Assume 360 days in a year.)

14) p = $800, r = 7%, t = 1 years

Use the compound interest formula to compute the total amount accumulated.

15) $11,000 for 4 years at 3% compounded annually

Find the mean of the set of data. Round your answer to the nearest tenth.

16) 6, 16, 13, 18, 12, 13, 1, 2, 10

Find the median of the set of data.

17) 4, 7, 19, 24, 30, 39, 49

Find the mode or modes for the set of numbers.

18) 5, 9, 54, 3, 2, 8, 40, 1, 4, 16

Find the midrange of the set of data.

19) 14, 20, 2, 4, 19, 20, 22, 4, 12
