4. There are o sets below, with a number to the left of each set. Create a number from these numbers based upon which sets are linearly dependent. For example, if the only sets that are linearly dependent are 2, 3, 7, and 8, then create the number 2378, and give this as your answer. 1 . 1 2 . 3. 4. 5. 6. 7 . is a linearly dependent set. Determine whether the second vector in the set can be written as a linear combination of the first and third vectors. If it can, then give the sum of the weights. If it cannot, then enter 999. is a linearly dependent set, and in fact, the fourth vector in this set can be written as a linear combination of the first 3 vectors. Give the sum of the
