Explanation Given: The matrices are A : = [ 2 0 5 2 1 2 ] and B : = [ 1 − 1 2 0 3 − 2 ] . Approach: A matrix is a rectangular array of numbers arranged in rows and columns where the element in the i th row and j th column is a i j . Formally, the sum of two matrices is given by A + B = [ a i j ] + [ b i j ] = [ a i j + b i j To determine (b) To find: The difference of 7 A − 4 B .

Question 2 A nickel-titanium alloy is used to make components for jet turbine aircraft engines. Cracking is a potentially serious problem in the final part because it can lead to nonrecoverable failure. A test is run at the parts producer to determine the effect of four factors on cracks. The four factors are: pouring temperature (A), titanium content (B), heat treatment method (C), amount of grain refiner used (D). Two replicates of a 24 design are run, and the length of crack (in mm x10-2) induced in a sample coupon subjected to a standard test is measured. The data are shown in Table 2. 1 (a) Estimate the factor effects. Which factor effects appear to be large? (b) Conduct an analysis of variance. Do any of the factors affect cracking? Use a = 0.05. (c) Write down a regression model that can be used to predict crack length as a function of the significant main effects and interactions you have identified in part (b). (d) Analyze the residuals from this experiment. (e) Is there an…
