Deshad runs a river tubing company that serves 300 customers a day during sunny, summer days. He knows that 45% of the customers
rent life jackets. Suppose that Deshad calculates the daily proportion p ^ on top of customers who rent life jackets from his sample of 300. We can assume the customers each day represent a random sample.
First let as solve all unit pirce whistles 21.25 / 25 = $ 0.85 per unit 36 / 50 = $ 0.72 per unit 60 / 80 = $ 0.75 per unit kazoos 10 / 25 = $ 0.4 per unit 18.50 / 50 = $ 0.37 per unit 27.20 / 80 = $ 0.34 per unit a.) $ 0.85 - $ 0.72 = $ 0.13 b.) 10 / 25 = $ 0.4 per unit c.) he must order 80 kazoos she should order
To see if a table of values represents a linear function, check to see if there's a constant rate of change. If there is, you're looking at a linear function!
