Select Is a Function or Is not a Function to correctly classify each relation. {(3, 2),(6, 4),(9, 6),(12, 8)}

{(2, 3),(2, 5),(3, 6),(9, 4)}

{(2, 4),(6, 3),(4, 8),(6, 6)}

{(3, 4),(5, 2),(6, 8),(6, 4)}

Which ones are functions and which ones aren't?

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1

Look at this pattern ; 1,4,9, number 10000 belongs in this pattern . what’s the place of this number?
