The density function of the continuous random variable X, the total number of hours, in units of 100 hours, that a family runs a vacuum cleaner over a period of one year, is given. Find the average number of hours per year that families run their vacuum cleaners. f(x) = 9 5x, 6?5 9 5 5 0, The average number of hours per year that families run their vacuum cleaners is (Round to the nearest whole number as needed.) 0
The density function of the continuous random variable , the total number of hours, in units of 100 hours, that a family runs a vacuum cleaner over a period of one year, is given. Find the average number of hours per year that families run their vacuum cleaners. The average number of hours per year that families run their vacuum cleaners is (Round to the nearest whole number as needed)
Expert Answer
The given scenario involves a random variable X, which represents the total number of hours (in units of 100 hours) that a family runs their vacuum cleaner. To determine the average or mean number of hours per year that families run their vacuum cleaners, we use the concept of expectation. The average is calculated as ,limits are given in square brackets [].
