You attempt an obstacle course five times. the table shows the amounts of time that it takes you to complete the course on your first four attempts. for what values of x will you have a mean time no greater than 150 seconds? this is the table. time (seconds) 136 127 154 166 x

You first multiply 150 by 5 to get 750. Then you add 136, 127, 154, and 166 together. This would give you 583. Then you subtract 583 from 750 to get 167. This means to get no greater than 150 for a mean, you need to get 167 seconds or less.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
