Some fireworks displays can reach heights of over 300 meters. The height of a firework shell, in meters, 1 seconds after launch can be modeled by the function f (t) = -4.912 + 80t. How many seconds does it take for the shell to first reach a height of 300 meters round to the
nearest tenth of a second.

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

step-by-step explanation:

where is the question is there is a formula or is there not one
