20. A dietician prepares a diet specifying the amounts a patient should eat of the four basic food groups: group I, meats; group II, fruits and vegetables; group III, breads and starches; group IV, milk products. Amounts are given in "exchanges" that represent 1 oz (meat), 1/2 cup (fruits and vegetables), 1 slice (bread), 8 oz (milk), or other suitable measurements. Complete parts (a) through (c) below. a) The number of "exchanges" for breakfast for each of the four food groups, respectively, are 3,2,2, and3; for lunch,4,3,1, and 2; and for dinner, 5,4,3, and 2. Matrices are written as rows×columns. Fill in the rows or columns in the same order as the given data. Write a 3x4 matrix using this information. (b) The amounts of fat, carbohydrates, and protein (in appropriate units) per exchange in each food group, respectively, are as follows. Use this information to write a 4×3 matrix. c) There are 14 calories per exchange of fat, 8 calories per exchange of carbohydrates, and 13 calories per exchange of protein. Summarize this data in a 3×1 matrix. Write the 3x1 matrix. Again, remember to keep the order in which the data is given
