Question

The histogram to the right represents the weights​ (in pounds) of members of a certain​ high-school math team. How many team members are included in the​ histogram? A histogram has a horizontal axis labeled from less than 115 to 235 plus in intervals of 20 and a vertical axis labeled from 0 to 6 in intervals of 1. Vertical bars, 20 units wide and centered on the horizontal axis values, have heights as follows: 115, 1; 135, 4; 155, 3; 175, 1; 195, 5; 215, 2; 235, 3. 115 135 155 175 195 215 235 0 2 4 6 The histogram represents nothing math team members.

Answer 1

Answer:

19

Step-by-step explanation:

The vertical axis of a histogram indicates the total amount of people that meet the weights indicated in the x-axis in the analysed population.  From data we can construct the following table:

x-axis   y-axis  

115        1

135       4

155       3  

175        1  

195       5  

215       2  

235      3

So there are: 1+4+3+1+5+2+3 = 19 team members included in the​ histogram.
