Abiologist doing an experiment has a bacteria population cultured in a petri dish. after measuring, she finds that there are 11 million bacteria infected with the zeta-virus and 5.2 million infection-free bacteria. her theory predicts that 50% of infected bacteria will remain infected over the next hour, while the remaining of the infected manage to fight off the virus in that hour. similarly, she predicts that 80% of the healthy bacteria will remain healthy over the hour while the remaining of the healthy will succumb to the affliction modeling this as a markov chain, use her theory to predict the population of non-infected bacteria after 3 hour(s).
(x + 4) - (x + 2) = x + 3 --> x = -1
the three numbers are:
-1, 1, 3
6/10 rounding to the nearest half would be 1, not 0.
reason for this: here is a number line to you!
left line = 0
middle line = 1/2
right line = 1
here is another rule!
0/10, 1/10, 2/10, 3/10, 4/10 = rounded to the nearest half would be 0
5/10, 6/10, 7/10, 8/10, 9/10, 10/10 = rounded to the nearest half would be 1.
so 6/10 rounded to the nearest half is 1.
hope this !
plz mark brainliest!
