Consider two sequences of random variables {xn) and {yn} such that xn x and yn4 y. let a and b be two real constants. define a new random sequence zn = axn + byn. does this sequence converge in mean-square and if so, to what limit?

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
