Step-by-step explanation:
The number of colonies will be given by
Where A is the final number of colonies, P is the initial number, r is the rate of growth in decimal and t is time
Taking r as 0.144 and t as 12 hours then P is given as 725
When t is 1 day, 24 hours then
The nth term of the arithmetic series is given by
Now find the first five terms
Thus the first five terms of the series is
Now find the partial sum of the series:
Answer: Symmetrical, Bell-shaped
Step-by-step explanation:
The Normal Probability Distribution is very popular among all because of its unique mathematical characteristics like
- Normal distributions are symmetric.
- They are unimodal (i.e. it has only one mode).
- All mean, median, mode are equal.
- It is symmetrical around center where mean, median and mode lies.
- Its curve is always a bell shaped curve.
Hence, the major characteristics of a normal probability distribution:
Symmetrical, Bell-shaped
