Disaster data can be used to inform policy decisions to help reduce disaster risks and build resilience. Geological investigations and historical record of earthquakes in New Zealand show that the average number of earthquakes with magnitude 4-4.9 is 445 per year. We will assume the number of earthquakes of this magnitude per year follows a Poisson distribution. Approximate the probability that at least 505 earthquakes occur in a year. Give your answer with 4 digits, e. g. 0.1234

Which expression is equivalent to 4 square root 6 divided by 3 root 2

Which mathematical statements are true? 1) if 3 is an odd number, then 3 times 3 is an even number. 2) if 6 is less than 7, then 4 is greater than 7. 3) six is divisible by 3, and 10 is a multiple of 2. 4) the average of the data is greater than the largest value in the data, or it’s less than the largest value in the data. 5) the slope of a linear graph is its rate of change, and the graph’s y-intercept is the initial value. 6) if an equilateral triangle has equal angles, then all its angles will measure 45°.

Anumber cube is rolled two times in a row. find the probability it will land on 2 on the first roll and a number greater then 4 on the second roll
