Step-by-step solution

2 steps

  1. Read the number of countries for each range of athletes from the histogram.

    • For 1-5 athletes, there are 30 countries.
    • For 6-10 athletes, there are 30 countries.
    • For 11-15 athletes, there are 40 countries.
    • For 16-20 athletes, there are 40 countries.
    • For 21-25 athletes, there are 50 countries.

  2. Sum the number of countries from all ranges to find the total number of countries that participated.

    Total countries=30+30+40+40+50\text{Total countries} = 30 + 30 + 40 + 40 + 50 Total countries=60+40+40+50\text{Total countries} = 60 + 40 + 40 + 50 Total countries=100+40+50\text{Total countries} = 100 + 40 + 50 Total countries=140+50\text{Total countries} = 140 + 50 Total countries=190\text{Total countries} = 190

    The total number of countries that participated in the competition is 190\boxed{\text{190}}.
