Rosie read 8 chapters in her book in four hours. if each chapter is 149 pages long, how many pages did rosie read in four hours? will give brainliest to either the first person to answer or the right answer

The random variable x is the number of occurrences of an event over an interval of ten minutes. it can be assumed that the probability of an occurrence is the same in any two-time periods of an equal length. it is known that the mean number of occurrences in ten minutes is 5.3. the appropriate probability distribution for the random variable

Find the solution of this system of equation -7x+y=-20 9x-3y=36

Determine the required value of the missing probability to make the distribution a discrete probability distribution. x p(x) 3 0.23 4 ? 5 0.51 6 0.08 p(4) = nothing  (type an integer or a decimal.)
