Evaluate the expression below.
(8.1+7.9)x - (25 division 5)x

Add 1/7 + -1/7 your answer should be reduced to its smallest form and should not be an improper fraction

The line y = x + passes through (−3, 7) and is parallel to y = 4x − 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
