(T/F) If the linear system Az = b is consistent, then bis in the span of all the column vectors of A. (T/F) Suppose ₁, 2, ₁, 2 E R². Suppose (₁, 2) is linearly independent, (₁, ₂) is linearly independent. Then (₁+₁, 2+2) is linearly independent. (T/F) Let A be a matrix. If N(A) = Span(₁,...), then = ₁,..., are all solutions to the homogeneous equation Az = 0.

Define interset.

A) A class of 2018 graduates  were 1250 students, 40% of them were female students and the rest were Male, 10% of the female students  got a grade of A and 10 students of the female grades A were international students.  Class of 2019 had 875 Male students,  also 10 female students  got an A in their grade in class 2019, where the total number of students  did not change from last year. Calculate the following. Show your calculations step by step.  The number of female students. The number of Female students with a grade A  The percentage of the female international students graded A out of the total number of  female students with a grade A. What is the percentage increase  or decrease in the number of Male students in comparison to class 2018? What is the percentage of female students  who got A out of the female students? B) 23, 30, 1,49, 2, 36, 7, 23, 13,9, 30, 17, 20. Calculate the mean, median and mode.
