Suppose the force acting on a column that to support a building is a normally distributed random variable x with mean value 15.0 (kips) and standard deviation 1.25 (kips). calculate the following probabilities: (1) (2 points) p(x ≥ 17.5). (2) (2 points) p(14 ≤ x ≤ 18).

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.
