The data shows the speed, in miles per hour, of motorists on a stretch of road.

42, 35, 44, 31, 47, 41, 36, 34, 39, 18, 37, 32, 37, 33, 43, 41, 44, 47, 46

Which is/are true about the data? Select all that apply.

18 miles per hour is an outlier
47 miles per hour is an outlier
the outlier decreases the mean speed
the outlier decreases the median speed
if the outlier were changed to 35 miles per hour, the standard deviation would increase
if the outlier were changed to 35 miles per hour, the interquartile range would increase

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
