Please help quicckkk! I'm going to be posting LOTSS of questions in a few minutes so please stay active guys! The equation of a curve is y = x^2 − 6x + k, where k is a constant. (i) Find the set of values of k for which the whole of the curve lies above the x-axis. [2] (ii) Find the value of k for which the line y + 2x = 7 is a tangent to the curve. [3]

Over the course of the school year, you keep track of how much snow falls on a given day and whether it was a snow day. your data indicates that of twenty-one days with less than three inches of snow, five were snow days, while of the eight days with more than three inches of snow, six were snow days. if all you know about a day is that it is snowing, what is the probability that it will be a snow day?
