**FSOT Mathematics - Answer Key**

1. A. Mean represents the sum of all rates divided by the total number of rates. Median represents the number below and above which an equal number of numbers fall. Mode represents the most frequently occurring number.

2. D. definition

3. D. Probability is traditionally shown as a number between 0 and 1. For example when tossing a coin, the probability of heads and tails are equal at 0.5. However, it can also be shown as odds against or as a fraction.

4. D. Add all expenditures in pesos. Divide by 10.85 to convert back to American dollars.

5. B. Percentile ranking indicates the percentage of scores that ranking is above. A 90th percentile ranking means that score was higher than 90% of scores. This alone cannot be construed as proficient since it is only a measure of comparison, not a measure of performance to standards.

6. B. Weighed average would be calculated with this formula: (0.50)(4.5) + (0.10)(4.5) + (0.20)(4.25) + (0.20)(3.75) = Employee score

7. B. Apply numbers to formula to find that A=$4250.00. Subtract principle amount of $2000.00 to find simple interest earned.

8. C. Quotient is the result of division of one number into another.

9. B. Portion or year two sales = base or year one sales x rate. Rate is 123% or 1.23.

10. A. Rate = Portion or profit / base or total sales. Rate = 300,000/4,500,000.

11. C. definition

12. C. Range is the difference between the highest and lowest numbers in a set. In this case, the 100 point scale is irrelevant.

13. A. Independent variables are those that are manipulated in research or those variables used to assign subjects to experimental groups. Dependent variables are those that are simply measured or recorded.

14. D. Nominal variables are qualitative in nature and can not be quantified. Interval, ratio, and ordinal variables are all quantifiable in nature.

15. B. Algorithms are a precise set of operations or steps that produce a specific result. Example: 1. Door opens 2. 5 seconds pass 3. No code entered = Police notified

16. A. Total hours worked X hourly rate / widgets produced = widget per payroll dollar. John was $4/widget making him the most cost effective. Amy was $4.625/widget and Dave was $4.453/widget.

17. A. This is the basic formula for determining probability of an event occurring.

18. A. This is the best choice. The approximate conversion commonly used is 1 meter = about 1 yard. Exact is 1 = 1.0936... The approximate conversion commonly used is 1 meter = about 3 feet. Exact is 1 = 3.281.

19. B. Divide 100 by 30 to determine gallons needed = 3.33333. Multiply times 3.785 = 12.617.

20. D. Digits are only 0,1,2,3,4,5,6,7,8,9.

21. C. The order is Brackets, Parenthesis, Exponents, Multiplication or Division, Addition or Subtraction.

22. C. The area of a triangle is calculated by ½ base times height.

23. D. This can be calculated by determining 15% of 5300 (5300 X 0.15) which equals 795 and subtracting that from 5300 or by simply calculating 85% of 5300 (5300 X 0.85).

24. B. Rate = distance / time. Rate = 890 /60. Rate = 14.8

25. D. Total cost = 850,000/0.12 which equals 7,083,333.

26. A. Exponential growth is defined as that growth which is in direct proportion to amount present as is true with an investment in which interest is compounded continuously.

27. D. The simple fact of using qualitative data would not be reason enough to declare a statistical study ineffective. However, using too small of a sample can prevent your data from accurately reflecting the total population. Additional, misleading or misapplication of percentages, ratios, etc. can create inaccurate data about the total population as well.

28. B. Mode is the value in a set that appears most frequently. Bimodal or multimodal means there is more than one mode.

29. C. Calculate individual percentage raises by subtracting old salary from new salary, dividing the difference by the old salary, and dividing by 100. Add all percentage raises together and divide by 5.

30. A. Calculate total budget increase as 765,000 X 0.15 = 114,750. Calculate amount available for additional personnel as 114,750 X 0.85 = 97,538.

31. B. A kilogram is a measure of weight or mass and equals approximately 2.2 pounds. Although tons also measure weight or mass, it is a much larger tool. Inches measure length or distance and quarts measure volume.

32. D. Calculate reduction percentage as old number minus new number divided by old number times 100. 110 - 82 = 28 / 100 = 0.25 X 100 = 25%

33. D. Median is the middle number of a set of numbers arranged by size. If there are two middle numbers as with a set with an even number, the median is the mean or average of those numbers.

34. A. Multiply $1350 by 0.850 which equals 1148. Divide this by 6 for the daily rate.

35. C. There is a three hour difference between New York in EST and Lost Angeles in PST. Subtract three hours from 10:00 to obtain PST when flight departs and then add the five hour flight time to determine arrival time.

36. A. A parameter is a numerical measurement of one characteristic or quality of the population being studied.

37. B. Standard deviation is a common way to measure the statistical dispersion of data, or in other words, how spread out each is from the mean.

38. C. A permutation is the number of different ways a set of objects can be arranged.

39. A. Relative frequency can be described as the number of times an event occurs divided by the number of opportunities it had to occur.

40. A. $325,000 divided by 12 equals an average salary of about $27,000. This is $9,000 below the organization's average of $36,000. $9000 divided by $36,000 equals 0.25 times 100 equals 25%.
