Explanation Given: P ( Z > 2.27 ) Approach: Take values from table 2 in appendix D. Calculation: Consider the given probability, P ( Z > 2.27 ) Draw perpendicular from the x -coordinate equal to 2.27 which is parallel to the y -axis on the standard normal curve. The shaded area under the curve towards the right side from drawn perpendicular line is referred to the probability, P ( Z > 2.27 ) . Thus, the probability P ( Z > 2 To determine (b). The value of probability P ( Z > 2.27 ) of the standard normal variable Z corresponding to the shaded area under the standard normal curve.

Consider the function f(x) = x²-1. (a) Find the instantaneous rate of change of f(x) at x=1 using the definition of the derivative. Show all your steps clearly. (b) Sketch the graph of f(x) around x = 1. Draw the secant line passing through the points on the graph where x 1 and x-> 1+h (for a small positive value of h, illustrate conceptually). Then, draw the tangent line to the graph at x=1. Explain how the slope of the tangent line relates to the value you found in part (a). (c) In a few sentences, explain what the instantaneous rate of change of f(x) at x = 1 represents in the context of the graph of f(x). How does the rate of change of this function vary at different points?
