Unit nine statistics and lesson seven displaying data graphically practice five questions. The first question is Geraldo surveyed group of people and asked him how many tattoos they had. His results are represented in the circle graph. How many people did he serve on the graph we have 11+7 on the right side we had 35 and 1-2 on the bottom we had 18 and 3-4 on the left side. We had 13 and 5-6.

Answer 1

To find the total number of people surveyed by Geraldo, we need to add up the numbers represented in the circle graph.

Number of people with 1-2 tattoos: 18
Number of people with 3-4 tattoos: 13
Number of people with 5-6 tattoos: 7
Number of people with 7 or more tattoos: 11

Total number of people surveyed = 18 + 13 + 7 + 11 = 49

Therefore, Geraldo surveyed 49 people.
