A scatter plot was made to show the record for the 100-meter dash over several years at Meander High

School. The equation of the scatter plot's trend line

is y = - 14x + 12.5 where y is the record in seconds

and x is the number of years since the year 2000.

Use the trend line equation to predict the year

that the record for the 100-meter dash was

11 8 seconds

step-by-step explanation:

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
