Which one of the following is a valid conclusion from this histogram?The median time between eruptions is between 70 and 80 minutesThe distribution of times between eruptions is roughly log normalShorter intervals between eruptions are more likely than longer intervalsThe geyser has two sources erupting at different rates

The histogram below shows the distribution of waiting times in minutes between 300 successive eruptions of a geyser.

Suppose that a volcano is erupting and readings of the rate r(t) at which solid materials are spewed into the atmosphere are given in the table. The time t is measured in seconds and the units for r(t) are tonnes (metric tons) per second. (Use 6 equal subintervals.)t 0 1 2 3 4 5 6r(t) 2 8 20 32 46 52 60(a) Give upper and lower estimates for the total quantity Q(6) of erupted materials after 6 seconds.Q(6) = tonnes (lower estimate)Q(6) = tonnes (upper estimate)(b) Use the Midpoint Rule to estimate Q(6). (Use 3 equal subintervals.)Q(6) = tonnes

21. These are expected to happen when there is a heavy rainfall after an eruption. It can cover an entire place. These can flood communities with ash and water mixture that can cause death.*2 pointslava flowsfloodingmudflowslateral blasts
