scZoUnD [109]

Answer:

10 buildings

Step-by-step explanation:

<em>Incomplete question: Missing Attachment</em>

<em>I will answer your question with the attached histogram</em>

<em></em>

Required

Determine the number of tall buildings that had more than 60 floors

The histogram can be interpreted as follows:

\begin{array}{cccccc}{Floors} & {1-20} & {21-40} & {41-60} & {61-80} \ \\ {Buildings} & {10} & {5} & {15} & {10} \ \end{array}

More than 60 floors is represented with the following group: 61 - 80

The frequency of group 61 - 80 is 10

<em>Hence, 10 buildings had more than 60 floors</em>
