Before Cole walks his dog, his activity tracker shows he has already walked 3.8 miles. He and his dog walk 2.6 miles per hour. Write a linear equation in slope-intercept form for the number of miles, y, after x hours of walking. Find the number of miles on Cole’s activity tracker after 1/2 hour of walking.

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
