INTRODUCTION TO OPERATIONS RESEARCH Introduction to operations research Question(Question 5) Solved a 3-variable maximisation Linear Program with the objective function ofz = 4x₁ + 3x₂ + 7x3. The Linear Program has two "<" constraints, and its optimal solutionis (x₁, x₂, x3, S₁, S₂ ) = (7, 0, 0, 2, 0), z* = 28.First situation: the objective function changes to maximisez = 4x₁ + 7x₂ + 7x3.Second situation: the objective function changes to maximise:z = 3x₁ + 3x₂ + 7x3.Analyse separately and specifically for each situation, what must be checked if were todetermine whether the current basis remains optimal after the change is made. Justify theanswers.

Given: The objective function of a linear program having two "≤" constraints is z=4x1+3x2+7x3. The…

The same study also took samples from ocean beaches. Five samples were taken from each of 18 different shorelines worldwide, for a total of 90 samples of size 250 mL. The mean number of plastic microparticles found per 250 mL of sediment was 18.3 with a standard deviation of 8.2. (a) Find a 90% confidence interval for the mean number of polyester microfibers per 250 mL of beach sediment. Round your answers to two decimal places.

Your Turn: The Gas Guzzler Tax is imposed on manufacturers on the sale of new-model cars (not minivans, sport utility vehicles, or pickup trucks) whose fuel economy fails to meet certain statutory regulations, to discourage the production of fuel-inefficient vehicles. The tax is collected by the IRS and paid by the manufacturer. The table (top right) shows the amount of tax that the manufacturer must pay for a vehicle's miles per gallon fuel efficiency. 12.5 13.5 MPG (M) 14.5 15.5 16.5 17.5 18.5 19.5 20.5 21.5 22.5 Tax per Car (T) $6400 $5400 $4500 $3700 $3300 $2600 $2100 $1700 $1300 $1000 $0 1.
