To find √15, Ben found 3²-9 and 4²= 16. He said that since 15 is between 9 and 16, √15 must be between 3 and 4. He thinks a good estimate for √15 is 3+4= 3.5. Show the approximate in a 2 number line. Is Ben's estimate high, low or correct? Explain.

Create a graph for the demand for starfish using the following data table: quantity/price of starfish quantity (x axis) of starfish in dozens price (y axis) of starfish per dozen 0 8 2 6 3 5 5 2 7 1 9 0 is the relationship between the price of starfish and the quantity demanded inverse or direct? why? how many dozens of starfish are demanded at a price of five? calculate the slope of the line between the prices of 6 (quantity of 2) and 1 (quantity of 7) per dozen. describe the line when there is a direct relationship between price and quantity.
