In exercise below, determine whether the set S is linearly independent or linearly dependent. S = {(1,-4,1), (6,3,2)} What is a non linear function? Define the term Ordered pair. Give an example of a scenario that can be modeled with a linear equation...
(Problem 2) Using the data from Problem #1 ? (a ? 4 points) Construct a histogram ? you may draw it by hand, if desired. (b ? 2 points) In what interval must the median lie? Assume the largest recorde Find x and y so that the ordered data set has a mean of 42 and a median...
As for the second situation “#2. IN and comma-separated list of values”: >SELECT * >FROM a >WHERE column IN (‘1, 2, 3’) Why quote all values at the same time? To achieve what you want one can write: SELECT * FROM a WHERE column IN (‘1’, ‘2’, ‘3’) So nothing...
