Student scores on exams given by a certain instructor have a mean of 74 and a standard deviation of 14. This instructor is about to give two exams, one to a class of size 25 and the other to a class of size 64. (a) Approximate the probability that the average test score in the class of size 25 exceeds 80. (b) Repeat part (a) for the class of size 64. (c) Approximate the probability that the average test score in the larger class exceeds that of the other class by over 2.2 points.

You have learned about the six trigonometric functions, their definitions, how to use them, and how to represent them graphically. the sine, cosine, and tangent trigonometric functions can be paired with their reciprocal functions, cosecant, secant, and cotangent, respectively. think about how each function is related to its reciprocal function.how are the graphs of the reciprocal functions related to their corresponding original functions? what happens to the graphs of the reciprocal functions as x approaches the zeros of the original functions? describe how you would teach friends with different learning styles (visual-spatial, aural-auditory, verbal-linguistic, physical-bodily-kinesthetic, logical-mathematical, social-interpersonal, and solitary-intrapersonal) how to graph the reciprocal functions
