The height of the missing rectangle measures 0.15. The image includes the mentioned histogram that outlines the relative frequencies for the categories [0,1], [1,2], [2,3], [4,5], and [5,6] for Silver in ppm. The rectangle for the class [3,4] is the only one that is missing. Each rectangle's height represents the relative frequency for its respective class. The total of the relative frequencies must sum to 1; this is determined by dividing the absolute class frequency by the total sample size. Therefore, by summing the known relative frequencies and subtracting from 1, we can find the missing relative frequency, which corresponds to the height of the absent rectangle. To find the known relative frequencies, we add: 0.2 + 0.3 + 0.15 + 0.1 + 0.1 = 0.85. The missing frequency turns out to be 1 - 0.85 = 0.15. Hence, the height of the missing rectangle is determined to be 0.15.

Answer:
Thirty-seven thousand fifteen point zero eight
Step-by-step explanation:
Duration = distance ÷ velocity
duration = (5 1/5) ÷ (8 2/3)
duration = (26/5) ÷ (26/3)
= 26/5 × 3/26
= 3/5 of an hour <===
