Alan and austin are truck drivers. the dot plots show the number of deliveries they made per week during 14 weeks that were randomly selected from the previous year. the interquartile range of alan's data is , and the interquartile range of austin's data is . comparing the values of the interquartile range for alan’s and austin's data, data shows more variation in the data values.

Recall the definition of a polynomial expression. find two polynomial expressions whose quotient, when simplified,is. use that division problem to determine whether polynomials are closed under division. then describe how theother three operations-addition, subtraction, and multiplication-are different from division of polynomials.
