an architecture student measured the heights of all the buildings downtown. building heights (meters) how many buildings are there in all? buildings
Answer
Explanation:
Step1: Read bar - height values
Read the height of each bar representing the number of buildings in each height - range. For 0 - 10: 1 For 11 - 20: 1 For 21 - 30: 9 For 31 - 40: 7 For 41 - 50: 9 For 51 - 60: 4 For 61 - 70: 2
Step2: Sum up the values
Add all the values together: $1 + 1+9 + 7+9 + 4+2$ $1+1 = 2$, $2+9 = 11$, $11+7 = 18$, $18+9 = 27$, $27+4 = 31$, $31+2 = 33$
