Just did it on edgu
The proportion of waiting times in the sample that are greater than or equal to 18 minutes is 0.16.
<h3>What is a histogram?</h3>
A histogram is used to represent data graphically. The histogram is made up of rectangles whose area is equal to the frequency of the data and whose width is equal to the class interval.
Number of people whose wait time was equal or greater than 18 minutes / total number of people = (2 + 2) / (6 + 7 + 8 + 2 + 2)
4/25 = 0.16

Answer:
277.5 square units
Step-by-step explanation:
To find the volume of a rectangular prism you must multiply length times width times height. When you multiply 7.5 x 9.25 x 4 you get the answer 277.5. Hope this helps:))
The answer would have to be D
