the histogram to the right represents the weights (in pounds) of members of a certain high - school debate team. how many team members are included in the histogram?
Answer
Explanation:
Step1: Identify frequencies for each class
The frequencies for the weight - classes are: For the class 105 - 115, the frequency is 4; for 115 - 125, the frequency is 1; for 125 - 135, the frequency is 5; for 135 - 145, the frequency is 4; for 145 - 155, the frequency is 2; for 155 - 165, the frequency is 5.
Step2: Sum up the frequencies
$4 + 1+5 + 4+2 + 5$ $= (4 + 1)+5+(4 + 2)+5$ $= 5+5 + 6+5$ $=10 + 6+5$ $=16 + 5$ $= 21$
Answer:
21
