Answer:
a). 8100 bacteria
b). 519 bacteria
c). Infinite
Step-by-step explanation:
Population growth of a bacteria is given by the exponential function,
f(x) =
Where f(x) = Population after time 't'
= Initial population
r = Growth rate
t = Duration after t hours
If "100 bacteria gets tripled every hour"
300 =
3 = 1 +
r = 100×(3 - 1)
r = 200
So the function is, f(x) =
a). Population after 4 hours,
f(4) =
= 8100 bacteria
b). Population after 90 minutes Or 1.5 hours
f(1.5) =
= 519.61
≈ 519 bacteria
c). Population after 72 hours,
f(72) =
= Infinite
It would help if we represent the information in form of two-ways table as shown below
The number of students who are not on probation is 104 students
There are 23 students who are not on probation and is satisfied is 81 students
The probability of students not on probation and is satisfied is 81/104
