    You are trying to decide from what company to buy your next 5-year supply of light bulbs. Would you look to the company whose light bulbs have the greatest mean or greatest median life?

    1) Mean - having a value intermediate between the values of other quantities.
    Ex. A mean diameter.
    2) Median - the middle number of a series. If the sequence has an even number of values, the median is the average of the two middle values. (Examples:) the median of 1, 3, 4, 8, 9 is 4. The median of 1, 3, 4, 8, 9, 10 is 6.
    One cannot answer your question
    based only on the above definitions.
    You would need to have more information about the company.

    Timmy has 180 marbles, some plain and some colored IF there are 32 more plain marbles than colored marbles, how many colored marbles does he have?

    Let x be the number of coloured marbles.

    Then, the number of plain marbles is x + 32.

    The sum of those two gives 180, that is:

    x + (x + 32) = 180

    Find x. :)

    And next time, start your own thread instead of piggybacking another one. Thank you!

    In December 1994, geologists found that the Bering glacier had come to a stop. Until that time, the glacier had been rushing forward at a rate of up to 300 feet per day. If the retreat resumes at the old rate, what integer represents how far the glacier will have moved after 28 days?

    Simply take your 28 days times 300 feet to get your answer.
