Mark as false any statement that isnever true or that is not necessarily true. Be able to justify your answers.1.An “exercise” can be solved by simply applying a routine procedure, but a “problem” is notroutine and requires a well-thought-out plan of attack.2.If there are infinitely many numbers involved in a problem, the Guess and Test problem-solvingstrategy is indicated.3.If 12 coins are arranged in the shape of an equilateral triangle, then there are 5 coins alongeach side.4.If the fourth phase of problem solving, “Looking Back,” we should look for other ways to solvethe problem even if we got the ‘right’ answer.5.When you are asked to make a generalization, you should use the Guess and Testproblem-solving strategy.6.If a problem involves a large array or diagram, a good strategy to try is “Use a Variable.”7.If a problem involves a physical situation, the “Draw a Picture” strategy may be appropriate.8.If a problem involves a sequence of numbers or figures, the “Draw a Picture” strategy may beappropriate.9.If a problem asks you to make a prediction or generalization, the “Look for a Pattern” strategymay be appropriate.10.If a problem asks “in how many ways” the “Look for a Pattern” strategy may be appropriate.11.The fourth term in the sequence 3, 5, 7, . . . must be 9.12.If a large cube is made up of 64 smaller cubes, then it has 16 cubes showing on each face of thelarger cube.13.Patterns in data may be easier to see if we arrange the data in tables.Multiple Choice.Mark the letter of the single BEST response. Be sure to read all the choices foreach problem before deciding.14.George Polya presented a four step process for problem solving which is still used extensivelytoday. Which of the following is NOT a step in his basic process?(a)Devise a plan.(b)Understand the problem.(c)Carry out your plan.(d)Draw picture.(e)Look back to analyze your solution.15.The Guess and Test problem-solving strategy can be useful when(a)there are only a few possible solutions to a problem.(b)the problem suggests an equation.(c)you are trying to develop a formula.(d)you need to find the measures of the angles in a triangle.(e)there is an unknown quantity related to known quantities
