A gas station earns $2.500 in revenue for each gallon of regular gas it sells, $2.550 for each gallon of midgrade gas, and $2.600 for each gallon of premium gas. Let X1, X2, and X3 denote the numbers of gallons of regular, midgrade, and premium gasoline sold in a day. Assume that X1, X2, and X3 have means μ1=1500, μ2=500, and μ3=300, and standard deviations σ1=180, σ2=90, and σ3=40, respectively.1) Find the mean daily revenue. 2) Assuming X1, X2, and X3 to be independent, find the standard deviation of the daily revenue. (Round the final answer to three decimal places.)
A gas station earns $2.60 in revenue for each gallon of regular gas it sells, $2.75 for each gallon of midgrade gas, and $2.90 for each gallon of premium gas. Let X1, X2, and X3 denote the numbers of gallons of regular, midgrade, and premium gasoline sold in a day. Assume that X1, X2, and X3 have means μ1 = 1500, μ2 = 500, and μ3 = 300, and standard deviations σ1 = 180, σ2 = 90, and σ3 = 40, respectively. a) Find the mean daily revenue. b) Assuming X1, X2, and X3 to be independent, find the standard deviation of the daily revenue.
