Here is a sketch of y=x^2 +bx + c The curve intersects the x-axis at (2, 0) and point P the y-axis at (0,-14). Work out the x-coordinate of the turning point of the graph. You MUST show your working and your final line should begin with The x-coordinate of the turning point is …

Consider a bag that contains 220 coins of which 6 are rare indian pennies. for the given pair of events a and b, complete parts (a) and (b) below. a: when one of the 220 coins is randomly selected, it is one of the 6 indian pennies. b: when another one of the 220 coins is randomly selected (with replacement), it is also one of the 6 indian pennies. a. determine whether events a and b are independent or dependent. b. find p(a and b), the probability that events a and b both occur.
