What are the dimensions of I? What are the dimensions of ˜I?Which is correct:A>=BA<=BA>BA<B A = Bor There isn't enough information to say definitively. Consider the following equation:\[ B = IA\tilde{I} \]where \( A \in \mathbb{R}^{3 \times 2} \) and \( I, \tilde{I} \) represent identity matrices.### ExplanationThis equation represents a matrix multiplication where:- \( B \) is the resulting matrix.- \( A \) is a matrix with dimensions \( 3 \times 2 \), which means it has 3 rows and 2 columns.- \( I \) and \( \tilde{I} \) are identity matrices. An identity matrix is a square matrix with 1s on the diagonal and 0s elsewhere. The dimensions of these identity matrices will depend on the context of matrix multiplication with \( A \), maintaining the compatibility of the multiplication.

d) the transpose of x. 2- If x= [2 8 5; 97 1], b=[2 4 5] find: a) find the maximum and minimum of x. b) add the vector b as a third row to x.
Hello, can you please help me with at least items d and e? I hope it's also explained well and has calculations if there are. I hope you don't do it in image form for easy copy. NOTE: Can you also not do it like this one: P(all three have disease)===≈P(D1∩D2∩D3)P(D1)·P(D2)·P(D3)(0.049)·(0.023)·(0.078)0.000088 Instead do it more simple like this: c)The probability that none of the three people have Alzheimer's =(1−0.049)*(1−0.023)*(1−0.078)=0.856655=(1-0.049)*(1-0.023)*(1-0.078)=0.856655 The probability that at least one of the individual have Alzheimer's =1−P(none of them have Alzheimers)=1−0.856655=0.143345
