The tables below give the numbers of some species of threatened and endangered wildlife in the United States and in foreign countries in 2015. United States Mammals Birds Reptiles Amphibians Fishes Endangered 74 79 14 20 93 Threatened 27 21 23 15 70 Foreign Mammals Birds Reptiles Amphibians Fishes Endangered 253 214 69 8 19 Threatened 20 17 20 3 (a) Write a matrix A that contains the number of each of these species in the United States in 2015 and a matrix B that contains the number of each of these species outside the United States in 2015. (Place endangered species in the first row and threatened species in the second row.) Mammals Birds Reptiles Amphibians Fishes A= Mammals Birds Reptiles Amphibians Fishes B = (b) Find a matrix with the total number of these species. Assume that U.S. and foreign species are different.(c) Find the matrix B - A. What do the negative entries in matrix B - A mean? O) There are more endangered/threatened species of this type in the United States than all other countries combined. O The population of species of this type is declining. O The population of species of this type is growing. O) There are less endangered/threatened species of this type in other countries than in the United States. ) There are no endangered/threatened species of this type
