Answer:
Empirical probability
Step-by-step explanation:
An empirical probability also known as experimental probability is the ratio of the number of outcomes in a trial/experiment of a specific event to the total number of trials.
Theoretical probability is probability based on reasoning not experiment.
Since an experiment was carried out 6000 times to determine the number of times 5 shows up, its an empirical probability.
7.3 km/y
at least if i did this correctly but that's always a stretch.
because it takes 50 days to complete a km
so 365/50 = 7.3

Two ways:
1) guess factors(trial and error)
2) use quadratic formula.
If you use this method then a = -3, b = -6 and c = -1
x = -b +/- [sqrt(b^2 -4ac)/2a]
substituting a, b, and c into our equation we get:
x = - (-6)+/- [sqrt ((-6)^2) - 4(-3)(-1))/2 (-3)]
x = + 6 +/- [sqrt (36 -4 (3)/-6)] if I didnt make a mistake in my signs
x = + 6 +/- [sqrt (36 -12)/-6)]
x = 6 +/- [sqrt (24)/-6] but sqrt 6 x sqrt of 4 = sqrt 24 hence
x = 6 +/- [ sqrt 6 x sqrt 4 /-6] that is:
x = 6 +/- [sqrt 6 x 2 /-6 ]
so x = 6 + [sqrt 6 x 2/-6] and x = 6 - [sqrt 6 x 2/-6]
