Arectangle has side lengths (x + 5) and (2x - 1) meters.

write and expression that represents the perimeter of the rectangle.

a. 3x +4
b. (x + 5) + (x + 5) + (2x - 1) + (2x - 1)
c. 6x + 8
d. (x + 5) (2x - 1)

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
