During a series of 100-meter races, the times of the runners are normally distributed with a mean of 12.5 seconds and a standard deviation of 0.3 seconds. Find the percent of runners that have a time between 11.6 seconds and 12.8 seconds. Explain how you got your answer. part 2. Find the probability that a randomly selected runner has a time greater than 12.8 seconds and less than 13.4 seconds

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
