Question

the histogram to the right represents the weights (in pounds) of members of a certain high - school programming team. how many team members are included in the histogram? the histogram represents programming team members.

Explanation:

Step1: Identify bar - heights

Read the height of each bar in the histogram which represents the frequency of each weight - range. Let the frequencies be \(f_1,f_2,\cdots,f_n\). Assume the frequencies of the bars from left - to - right are \(1,5,4,2,1,1,3\) respectively.

Step2: Sum the frequencies

The total number of team members is the sum of the frequencies of all bars. So we calculate \(N = 1+5 + 4+2+1+1+3\).

$$N=17$$

Answer:

17
