A certain store sells only sunglasses. Let the random variable x represent the number of sunglasses bought from the store on any day with mean 29 and standard deviation 11. Let the random variable y be the total revenue from this store on a randomly selected day. If the store charges $100 per pair of sunglasses, what are the mean and standard deviation of y? Mu Subscript y = $29 and Sigma Subscript y = $11
Mu Subscript y = $29 and Sigma Subscript y = $1,100
Mu Subscript y = $2,900 and Sigma Subscript y = $11
Mu Subscript y = $2,900 and Sigma Subscript y = $1,100
Mu Subscript y = $2,900 and Sigma Subscript y = $12,100
