About This Quiz

Algebra is one of the broad areas of mathematics, together with number theory, geometry and analysis. In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols; it is a unifying thread of almost all of mathematics.

    In what year was the difference between  men’s and women’s enrollment the  greatest? - ProProfs

    In what year was the difference between  men’s and women’s enrollment the  greatest?

    • 2000

    • 2001

    • 2002

    • 2003

    Correct Answer
    A. 2001
    Explanation
    The explanation for the given correct answer, 2001, is not available.

    Look at the box-and-whisker plot below.  Between what values does the middle  half of the data fall? - ProProfs

    Look at the box-and-whisker plot below.  Between what values does the middle  half of the data fall?

    • 12 and 18

    • 12 and 30

    • 18 and 26

    • 22 and 30

    Correct Answer
    A. 18 and 26
    Explanation
    The box-and-whisker plot represents the distribution of data. The box portion of the plot represents the middle half of the data, with the lower boundary of the box indicating the lower quartile (25th percentile) and the upper boundary indicating the upper quartile (75th percentile). The middle half of the data falls between these two quartiles. In this case, the lower quartile is 18 and the upper quartile is 26, so the middle half of the data falls between 18 and 26.

    Which type of graph would best display  the change in the number of student  absences over the school year? 

    • Circle

    • Line

    • Bar

    • Double-bar

    Correct Answer
    A. Line
    Explanation
    A line graph would best display the change in the number of student absences over the school year because it allows for a clear representation of the trend and fluctuations in the data over time. The x-axis can represent the different time periods (e.g., months or weeks) while the y-axis represents the number of student absences. The line connecting the data points will show the increase or decrease in absences throughout the school year, making it easier to identify any patterns or changes.

    Rate this question:

  • 5. 

    For the set {1, 1, 2, 4, 5, 6, 7, 8, 10, } which would NOT be affected if another  value of 10 was included?

    • Range

    • Mean

    • Median

    • Mode

    Correct Answer
    A. Range
    Explanation
    The range of a set is determined by the difference between the highest and lowest values. In this set, the highest value is 10 and the lowest value is 1, so the range is 10 - 1 = 9. Adding another value of 10 to the set would not change the highest or lowest value, so the range would remain the same.

    Rate this question:

    What is the median? - ProProfs

    What is the median?

    • 72

    • 80

    • 82.5

    • 83.2

    Correct Answer
    A. 82.5
    Explanation
    The median is the middle value in a set of numbers when they are arranged in order. In this case, the numbers are already in order, so we can easily identify the middle value. The median is 82.5 because it is the number that separates the lower half (72 and 80) from the upper half (83.2).

    Rate this question:

  • 7. 
    What might someone be incorrectly  influenced to believe in the graph  below? - ProProfs

    What might someone be incorrectly  influenced to believe in the graph  below?

    • Prices have been increasing

    • Prices have been decreasing

    • Prices tripled between 1999 and 2004.

    • Prices decreased between the years 2003 and 2004.

    Correct Answer
    A. Prices tripled between 1999 and 2004.
    Explanation
    Based on the graph, the line representing prices shows a steep upward trend from 1999 to 2004, indicating a significant increase in prices. Therefore, someone might be incorrectly influenced to believe that prices tripled between 1999 and 2004.

    Rate this question:

  • 8. 
    What is the mean? - ProProfs

    What is the mean?

    • 72

    • 80

    • 82.5

    • 83.2

    Correct Answer
    A. 83.2
    Explanation
    The mean is a measure of central tendency that represents the average value of a set of numbers. In this case, the given set of numbers is 72, 80, 82.5, and 83.2. To find the mean, we add up all the numbers and divide the sum by the total count of numbers. Adding up 72, 80, 82.5, and 83.2 gives us a sum of 317.7. Dividing this sum by 4 (the total count of numbers) gives us the mean, which is 79.425. However, none of the given options match this calculated mean. Therefore, the correct answer is not available.

    If you organized the data in a frequency  table, which could be intervals?  - ProProfs

    If you organized the data in a frequency  table, which could be intervals? 

    • 70–80 and 80–90

    • 70–79 and 80–84

    • 70–79 and 80–89

    • 70–80 and 81–90

    Correct Answer
    A. 70–79 and 80–89
    Explanation
    The answer is 70-79 and 80-89 because these intervals cover the entire range of data without any overlap. The first interval (70-79) includes all values from 70 to 79, and the second interval (80-89) includes all values from 80 to 89. This ensures that each data point falls into one and only one interval, allowing for an accurate representation of the frequency distribution.

    Rate this question:

  • 10. 

    One type of car gets 70 mi/gal and 4  other cars get 30 mi/gal. Why is this  statement misleading: “The average  mi/gal for these 5 cars is 38”?

    • The sample size is too small

    • The sample is biased.

    • The median is equal to the mode.

    • The mean is not a good descriptor for this data.

    Correct Answer
    A. The mean is not a good descriptor for this data.
    Explanation
    The statement is misleading because the average (mean) is not an accurate representation of the data in this case. The mean is heavily influenced by outliers, and in this scenario, the one car that gets 70 mi/gal significantly skews the average. The median would be a better measure of central tendency in this case as it is not affected by outliers.
